Book excerpt: The purpose of this research was to achieved selective hydrogenolysis of glycerol to 1,2-PDO (1,2-propanediol). Hydrogenolysis of glycerol was investigated in batch and trickle flow fixed bed continuous reactors. Raney catalysts and carbon supported precious catalysts were tested in the batch reactor. Ru/C and oxide-supported catalysts were tested in a continuous reactor. Parametric studies were performed and kinetics parameters were estimated with Raney copper catalyst in a batch reactor and with Cu/Al2O3 in a continuous reactor. The network of glycerol hydrogenolysis was studied on Cu/Al2O3. Cu/Al2O3 was investigated in the continuous reactor. Preparation methods, Cu loading and Cu catalyst support effects were studied. Catalyst characterization was performed to find out the factors that affected catalyst performance. Cu/Al2O3 catalyst was further modified by adding small amounts of Co and Ni to enhance the activity. The factors that affect the catalyst deactivation were also investigated. Raney Cu in the batch reactor and Cu/Al2O3 in the continuous reactor were the catalysts most selective to 1,2-PDO for glycerol hydrogenolysis. Cu catalyst on Al2O3 support of 18 wt % Cu loading prepared by co-precipitation method with ammonia is the most efficient catalyst for glycerol hydrogenolysis to 1,2-PDO. Catalyst characterization shows that the Cu/Al2O3 activity is related to the active Cu surface area on alumina support and the selectivity to 1,2-PDO is constant for the Cu/Al2O3 with different Cu surface area. Small amounts of Ni or Co improve the Cu/Al2O3 activity. The most effective deactivation factor for Cu/Al2O3 is coking or oxygenates on the spent catalyst.

Book excerpt: "Bioglycerol is the by-product which is produced largely from the microbial fermentation, hydrogenolysis of glucose in the mixture of polyols, fatty ester, soap manufacturing process and fatty acid production. Hydrogenolysis of glycerol is one of the most promising ways to convert glycerol and many work has been done towards 1,3-propanediol, 1,2-propanediol and 1-propanol using various metals and mixed-metal oxides such as W, Ru, Rh, Pt, Pd, Cu, Ni and different zeolites have been extensively used as the active components. It has been well documented that the presence of Bronsted acid sites leads to the formation of acrolein, while Lewis acid sites, and even basic catalysts, gives rise to hydroxyacetone as the main product. However, there is little research on the use of H-Beta zeolite as the catalyst and metals support for hydrogenolysis of glycerol. The investigations conducted in this study consist of the development of active catalysts as well as optimize process conditions, in the dehydration of glycerol to value-added chemicals. The use of different H2 pressures above 600-1200 psi, reaction temperatures 180-220 °C, reaction times (5-10 h), and the optimum catalyst/reactant ratios leads to significant impact of the liquid-phase reactions and the formation of products. Various bi-metallic catalysts based on W, Cu, Ni, Sr, Zr and Zn are studied with regard to the dependence of activity and stability in hydrogenolysis of glycerol with H-Beta zeolite support. All prepared catalysts are characterized using various analysis techniques such as N2 sorption, XRD, FTIR, and NH3-TPD and the obtained organic products are then further analyzed with the help of GC-FID and GC-MS"--Abstract, page iii.

This book was released on 2016 with total page 208 pages. Available in PDF, EPUB and Kindle. Book excerpt: Biodiesel is an attractive alternative fuel obtained from renewable resources and glycerol is produced as a major byproduct in the biodiesel industry. Upgrading glycerol to other valuable chemicals will contribute to an economic sustainability of the biodiesel industry. Valuable commodity chemicals such as 1,2-propanediol (1,2-PD), 1,3-Propanediol (1,3-PD) and 1-Propanol (1-PO) could be produced by catalytic hydrogenolysis. Although much work has been done towards the conversion of glycerol to 1,2-PD and 1,3-PD, the direct conversion of glycerol to 1-PO has not received much attention. From an industry point of view, the production of 1-PO is very interesting. 1-PO has potential applications as a solvent, organic intermediate and can be dehydrated to produce “green“ propylene for the production of polypropylene. Therefore, the development of a new process for the efficient conversion of glycerol to 1-PO will contribute to new “green” chemicals which will benefit the environment and make biodiesel processes more profitable as 1 kg of glycerol is produced for every 10 kg of biodiesel. In this research, heterogeneous hydrogenolysis of glycerol to 1-PO was carried out in a batch reactor using a bi-functional catalyst (prepared by a sequential impregnation method) in water, a green and inexpensive liquid medium. It was found that a bi-functional solid catalyst consists of a non-noble metal Ni for hydrogenation and an acidic function of silicotungstic acid (HSiW) supported on alumina (Al2O3) to be an active catalyst for the one-pot synthesis of 1-PO from glycerol and H2 in a liquid phase reaction. A systematic study has been carried out to assess the effects of operating conditions on the glycerol conversion. The catalysts were characterized using BET, XRD, NH3-TPD, TPR, TGA and FTIR techniques. The effect of different metals (Cu, Ni, Pd, Pt and Cs) supported 30HSiW/Al2O3 catalyst, heteroatom substitution (HSiW, HPW and HPMo) on NiHPA/Al2O3 catalysts and 10Ni/30HSiW supported on different supports (Al2O3, TiO2 and MCM-41) were studied to determine to what extent these components affect the catalytic activity of the NiHPAs/Al2O3 catalysts for the hydrogenolysis of glycerol. The effect of the preparation process on the catalytic activity and the structure of the catalyst was also studied. It was found that 1%Pt is the best promoter for the production of 1-PO in a stainless steel batch reactor (the selectivity to 1-PO was 59.2% at 45.3% conversion of glycerol). 1%Ni, a much cheaper metal, has fairly comparable reactivity to 1%Pt (the selectivity to 1-PO was 54.7% at 39.2% converison of glycerol). It was reported that the catalytic activity and thermal stability towards decomposition of the catalyst dependends on heteroatom substitution. Using NH3-TPD, XRD and FTIR it was found that while the Keggin-structure of HSiW and HPW supported catalyst is stable up to a treatment temperature of 450oC, the Keggin-structure of a HPMo supported catalyst was decomposed even at a treatment temperature of 350oC; the decomposition of HPMo into MoO3 is likely to be responsible for the inactivity of the NiHPMo catalyst for glycerol conversion. HPW and HPMo lost their acidity much more readily than HSiW, and a HSiW supported catalyst was the best candidate for 1-PO production. The catalytic activity and the acidity of 10Ni/30HSiW supported catalyst are influenced strongly by supporting 10Ni/30HSiW on different supports. Using XRD and FTIR it was found that the thermal treatment during the preparation process indeed affected the structure and the activity of the catalyst to some extent. The loss in activity of the catalyst, the decomposition in Keggin-structure of HPAs occur if the treatment temperature is higher than 450oC. It is important to note that this is the first report on a 10Ni/30HSiW suported catalyst developed for the one-pot hydrogenolysis of glycerol in a water media with high conversion of glycerol (90.1%) and high selectivity to 1-PO (92.9%) at 240oC and 580PSI hydrogen using a Hastelloy batch reactor. The activation energy Ea of this reaction is 124.1kJ/mol. Reaction pathways for the hydrogenolysis of glycerol using a bifunctional catalyst 10Ni/30HSiW/Al2O3 is proposed. It is believed that acidity plays an important role for the dehydration and Ni plays an important role for the hydrogenation. It is suggested that with acidic catalysts, the main route for the formation of 1-PO from glycerol is via either the hydrogenation of acrolein or further hydrogenolysis of 1,2-PD (and 1,3PD) where 1,2-PD (and 1,3-PD) and acrolein are the intermediate species in the formation of 1-PO from glycerol. The formation of 1,2-PD and 1,3-PD takes place through an initial dehydration of the primary or secondary hydroxyl groups on glycerol to give acetol or 3- hydroxylpropanaldehyde (3-HPA). The hydrogen activated on the metal facilitates the hydrogenation of acetol or 3-HPA to release 1,2-PD or 1,3-PD respectively. However, dehydration of 3-HPA on the acid sites forms acrolein. Further hydrogenolysis of diols or hydrogenation of acrolein produces 1-PO. 1,3-PD that is a very high value-added chemical can also be obtained from hydrogenolysis of glycerol using a Ni-HSiW supported catalyst. To improve the selectivity of 1,3-PD it is suggested that the catalyst should have high hydrogenation activity for the intermediate 3-HPA. The equilibrium between acrolein and 3-HPA in the hydration-dehydration step is important, so it is essential to tune the bi-functional catalyst and the conditions of the reaction to form 1,3-PD from 3-HPA. A study of promoter effects for the activity of catalyst to form 1,3-PD is recommended.

This book was released on 2014 with total page 282 pages. Available in PDF, EPUB and Kindle. Book excerpt: Biodiesel has shown great promise to supplement the fossil diesel since it is a renewable energy resource and is environmentally friendly. However, the major obstacle to biodiesel large scale commercialization is the high production cost; so converting glycerol, the by-product of a biodiesel process, into value-added products is an efficient way to promote biodiesel production. 1,2-propanediol (1,2PD), also known as propylene glycol, is an important commodity chemical used for many applications such as polyester resins, liquid detergents and anti-freeze. It can be produced via dehydration of glycerol into acetol followed by hydrogenation of acetol into 1,2PD using a bi-functional catalyst. Currently high pressure gaseous hydrogen added for hydrogenation causes safety issues as well as additional costs of hydrogen purchasing, transportation and storage. Therefore, the utilization of the in situ hydrogen produced by steam reforming of a hydrogen carrier could be a novel route for this process. In this work, processes of glycerol hydrogenolysis to produce 1,2PD have been developed using different hydrogen sources, i.e. molecular hydrogen and in situ hydrogen produced by steam reforming. Three different preparation methods were attempted to prepare a Cu/ZnO/Al2O3 catalyst in a glycerol hydrogenolysis process, which were oxalate gel-coprecipitation, Na2CO3 coprecipitation and impregnation. The catalyst prepared by oxalate gel-coprecipitation showed the highest activity for production of 1,2PD. It was also found that the addition of alumina did not only improve the activity but also enhanced the stability of the Cu/ZnO catalyst as shown by the catalyst recycling experiments. The morphological and chemical properties of the catalysts were characterized via XRD, NH3 TPD, TGA and TEM. Compared with other preparation methods, the Cu/ZnO/Al2O3 catalyst prepared by oxalate gel-coprecipitation exhibited a well-mixed form for all the metals as suggested by the XRD and TGA results; the particle size of the Cu/ZnO/Al2O3 catalyst was smaller as shown in the XRD and TEM results, and also based on NH3 TPD analysis the Cu/ZnO/Al2O3 catalyst showed stronger acidic sites. When Ni was loaded onto the Cu/ZnO/Al2O3 catalyst by oxalate gel-coprecipitation, it was found that the activity for acetol hydrogenation was improved but the overall glycerol hydrogenolysis reaction was slower. This was mainly due to the reduced amount of strong acidic sites caused by the addition of Ni as observed from the NH3 TPD results. 2wt% Pd supported on a Cu/MgO/Al2O3 catalyst was used in this process. Higher reaction rate and higher 1,2PD selectivity could be obtained compared with a Cu/ZnO/Al2O3 catalyst. However, a significant deactivation was observed when the spent catalyst was used. The catalyst deactivation was mainly due to catalyst sintering during the reaction resulting in a larger particle size as suggested by XRD results. The activation energies for the glycerol hydrogenolysis reaction using Cu/ZnO/Al2O3 and Pd supported on Cu/MgO/Al2O3 catalysts have been calculated. The activation energy was calculated to be 69.39kJ/mole using a Cu/ZnO/Al2O3 catalyst and 113.62kJ/mol using a Pd supported on Cu/MgO/Al2O3 catalyst. It is suggested that the reaction was chemically kinetically controlled using both catalysts and the reaction using the Pd supported on Cu/MgO/Al2O3 catalyst was more temperature dependent. It was found that the 1,2PD selectivity was strongly dependent on hydrogen pressure. The low 1,2PD selectivity at lower hydrogen pressure was due to the formation of by-products caused by side reactions with acetol. The kinetic data of acetol hydrogenation suggested that the acetol hydrogenation step was significantly faster than the overall reaction and hence the glycerol dehydration step was the rate-determining-step. In the glycerol hydrogenolysis process using in situ hydrogen, the activities of the Cu/ZnO/Al2O3 catalysts prepared by different methods were determined and the experimental results show that the catalyst prepared by oxalate gel-coprecipitation has the best catalytic activity for glycerol conversion and 1,2PD selectivity. With Ni loaded onto a Cu/ZnO/Al2O3 catalyst, the 1,2PD selectivity was improved and the glycerol conversion was lower. It might be because Ni could improve the steam reforming activity to produce more hydrogen, but due to the reduced strong acidic sites based on the NH3 TPD results glycerol conversion was decreased. Cu/MgO/Al2O3 catalysts prepared by oxalate gel-coprecipitation were used in this process and the activity was found to be higher, i.e. higher glycerol conversion and 1,2PD selectivity, compared with the Cu/ZnO/Al2O3 catalyst due to a higher amount of acidic sites based on the NH3 TPD results; the Cu/Mg/Al composition was optimized. When Ni was added into a Cu/MgO/Al2O3 catalyst, it was found that with only 1mole% Ni loaded, the glycerol conversion was lower than that without Ni loaded and the 1,2PD selectivity was slightly improved; when the Ni loading was increased to 5mole%, the catalyst was almost completely inactive, since when 5mole% Ni was loaded, the acidic sites were almost completely eliminated as observed from the NH3 TPD results. When Pd was added onto a Cu/MgO/Al2O3 catalyst the 1,2PD selectivity was significantly improved. When Pd was loaded, more surface hydrogen atoms were provided as observed from the H2 TPD results. Cu/ZnO/Al2O3 and Cu/MgO/Al2O3 catalysts have been recycled and reused to investigate the stability of the catalysts. All the catalysts were deactivated after they were recycled and reused, since it was apparent that catalyst sintering occurred during the reaction resulting in a larger particle size based on the XRD results. The deactivation of the spent catalyst was also possibly due to the formation of carbonate when the metals were contacted with CO2 which was formed via steam reforming.

Available in PDF, EPUB and Kindle. Book excerpt: The increase in the amount of glycerin in the market is a burden for all producers, especially those operating in the biodiesel sector: reuse options are in fact limited for the management of this by-product. Glycerol enhancement has therefore become a priority to improve the sustainability of the biodiesel industry. Nevertheless, the multifunctionality of glycerol makes it a promising precursor for different types of production (fuel/biofuel, chemical products). This conversion has therefore become a subject of multifaceted research that requires an exchange of knowledge across many sectors. In this book, different disciplines (chemistry, biology, engineering, etc.) have been taken into consideration to propose an interdisciplinary point of view on different aspects.
