Download or read book Conversion of Crude Glycerol from the Biodiesel Industry to Value Added Products written by Bijaya Kumar Uprety and published by . This book was released on 2017 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Crude glycerol is a major by-product of the biodiesel industries. For every 100 kg of biodiesel produced, approximately 10 kg of the byproduct glycerol is generated. With the large increase in biodiesel production, there is a glut in the glycerol produced. Presently crude glycerol is purified to its purer marketable form, burnt as a fuel or mixed with animal feed. However, none of these options contribute considerable revenues to the concerned biodiesel industry. Additionally, some of these routes are not environmentally friendly. It has thus become imperative to find ways to convert crude glycerol to some value-added products. Bioconversion of crude glycerol to microbial lipids is one possible way to valorize it. However, impurities like methanol, salts and soap present in crude glycerol inhibit the growth of microbes used for such conversions. The research work carried out in this thesis addressed these issues and developed tangible alternatives to overcome these problems. Initially the possible use of a heterogeneous catalyst Calcium oxide (CaO) attached to support alumina (Al2O3) for the production of biodiesel was studied. We found that the use of such a catalyst improves the purity of biodiesel and the glycerol produced. Crude glycerol obtained using such insoluble catalysts contained lower levels of impurities and can be converted relatively easily to other useful products. With CaO anchored on Al2O3 as catalyst, the purity of biodiesel and glycerol were found to be 97.66% and 96.36% respectively. The unanchored heterogeneous catalyst CaO resulted in purities of 96.75% and 92.73% respectively. As the byproduct glycerol containing smaller amount of impurities, the use of anchored heterogeneous catalyst is recommended. The potential use of ash from various sources as a cheap alternative heterogeneous catalyst was also studied. With the use of ash from birch bark and fly ash from wood pellets as catalysts, biodiesel and glycerol with purity in the ranges of 88.06%-99.92% and 78.18%-88.23% respectively were obtained. Since such catalysts are cheap and reusable, their application can reduce expenses and the use of environmentally unsafe compounds. The crude glycerol used in all experiments was obtained from a biodiesel producer in Ontario (Canada). It was found to contain 44.56 wt.% glycerol and many impurities including 13.86 wt.% methanol, 32.97 wt.% soap and 4.38 wt.%. After the characterization of the sample it was converted to microbial lipids using an oleaginous yeast Rhodosporidium toruloides ATCC 10788. When this strain was grown on crude glycerol, double the biomass (21.16 g/L) and triple the lipid concentration (11.27 g/L) was obtained compared to growth on pure glycerol media. The capacity of this strain to grow on crude glycerol with high levels of impurities and produce large amounts of lipids proves its robustness. Investigation of the effect of individual components on the lipid production ability of this strain showed it to be capable of using soap as a sole carbon source. This was also the reason for enhanced lipid production even in the presence of other impurities present in crude glycerol. The lipids obtained were rich in oleic acid (47.16%), a mono-unsaturated fatty acid (MUFA). Feedstock rich in MUFA are considered suitable for biodiesel production. Thus, the process of conversion of crude glycerol to microbial lipids can be integrated to existing biodiesel plants. This will help in the management of crude glycerol produced during biodiesel production, save transportation and disposal costs and contribute to the revenues of such industries.

This book was released on 2014-04-01 with total page 100 pages. Available in PDF, EPUB and Kindle. Book excerpt: Renewable energy sources and biofuel, including biodiesel, have been gaining increasing attention recently as a replacement for fossil fuels. However, their implementation in the general market depends on making these fuels more competitive. A convenient way to lower the cost of biofuel is to use the by-products as a potential source of energy, rather than treating them as waste. The industrial conversion of renewable resources into useful compounds, namely bio-based materials, has been receiving much attention from the environmental point of view. The crude glycerol from biodiesel production represents an abundant and inexpensive carbon source. Glycerol is yielded at about 10% as a by-product during the process of biodiesel production. The global biodiesel market is estimated to reach 39 billion gallons by 2020, growing at an average annual growth of 42%. Therefore, microbial conversion of raw glycerol into value added fermented products were investigated aiming to facilitate the utilization of waste glycerol.

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.

Available in PDF, EPUB and Kindle. Book excerpt: Rapid expansion of biodiesel industry has generated a huge amount of crude glycerol. This thesis aimed to explore utilization of glycerol for the production of solketal as an oxygenated fuel additive and 1, 2-propanediol as a pre-polymer via catalytic conversion. The thesis work may be divided into two major parts. In the first part, the thermodynamics and kinetics of the glycerol ketalization for the synthesis of solketal were investigated in a batch reactor. From this information, a continuous-flow process was designed, developed and optimized using pure glycerol. Crude glycerol (13 wt% purity) was successfully upgraded into a purified crude glycerol product (> 96 wt% purity) and was used as feedstock in a modified reactor for the synthesis of solketal whose economical feasibility was demonstrated. In the second part, B2O3 promoted Cu/Al2O3 catalysts were used for selective hydrogenolysis of glycerol to 1, 2-propanediol in a flow reactor. Surface properties, acidity, crystallinity, and reducibility of the catalysts were measured using N2 adsorption, NH3-temperature programmed desorption (TPD), X-ray diffraction (XRD), and H2-temperature programmed reduction (TPR), respectively. The fuels/chemicals products obtained were analyzed by GC-MS/FID and Fourier-transformation infrared spectroscopy (FTIR). he ketalization reaction equilibrium constants were determined experimentally in the temperature range of 293-323 K. The activation energy of the overall reaction was determined to be 55.6 ± 3.1 kJ mol-1. Langmuir-Hinshelwood equation was used to model the rate law. The activity of all catalysts tested in the flow reactor follows the order: Amberlyst wet Zeolite Amberlyst dry > Zirconium Sulfate > Montmorillonite > Polymax. At optimum conditions (25 ̊C, 500 psi, acetone-to-glycerol molar ratio of 4 and 2 h-1 WHSV), the maximum solketal yield from pure glycerol was 94±2% over Amberlyst wet. Ketalization of purified crude glycerol over Amberlyst wet, led to 93± 3% glycerol conversion with 92 ±2% solketal yield at the optimum conditions. In the glycerol hydrogenolysis process with 10 wt% aqueous solution of glycerol as the feed, 5Cu-B/Al2O3 catalyst demonstrated a very high activity, yielding 98 ±1% glycerol conversion and 98±1% 1,2-propanediol selectivity at the optimum conditions (250 ̊C, 6 MPa H2, and 0.1h-1 WHSV).

Book excerpt: HANDBOOK of BIOMASS VALORIZATION for INDUSTRIAL APPLICATIONS The handbook provides a comprehensive view of cutting-edge research on biomass valorization, from advanced fabrication methodologies through useful derived materials, to current and potential application sectors. Industrial sectors, such as food, textiles, petrochemicals and pharmaceuticals, generate massive amounts of waste each year, the disposal of which has become a major issue worldwide. As a result, implementing a circular economy that employs sustainable practices in waste management is critical for any industry. Moreover, fossil fuels, which are the primary sources of fuel in the transportation sector, are also being rapidly depleted at an alarming rate. Therefore, to combat these global issues without increasing our carbon footprint, we must look for renewable resources to produce chemicals and biomaterials. In that context, agricultural waste materials are gaining popularity as cost-effective and abundantly available alternatives to fossil resources for the production of a variety of value-added products, including renewable fuels, fuel components, and fuel additives. Handbook of Biomass Valorization for Industrial Applications investigates current and emerging feedstocks, as well as provides in-depth technical information on advanced catalytic processes and technologies that enable the development of all possible alternative energy sources. The 22 chapters of this book comprehensively cover the valorization of agricultural wastes and their various uses in value-added applications like energy, biofuels, fertilizers, and wastewater treatment. Audience The book is intended for a very broad audience working in the fields of materials sciences, chemical engineering, nanotechnology, energy, environment, chemistry, etc. This book will be an invaluable reference source for the libraries in universities and industrial institutions, government and independent institutes, individual research groups, and scientists working in the field of valorization of biomass.

Download or read book Glycerol written by Claudio J. A. Mota and published by Springer. This book was released on 2017-06-15 with total page 116 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is aimed at providing a concise discussion on the use of glycerol as a renewable raw material for the chemical industry. With the increasing use of biodiesel produced from oils and fats, there is a surplus of glycerol in the world. This abundant and rather cheap raw material can be transformed in commodities and specialty chemicals, as well as in fuels. The book describes the main processes of chemical transformation of glycerol, highlighting those that are currently in commercial use and pointing out potential processes to be used in the future. The first chapter introduces the concept of biofuel and briefly describes the production of biodiesel. It also highlights glycerol as the main byproduct of biodiesel synthesis and presents some numbers regarding the world production of glycerol. The second chapter shows the common uses of glycerol and addresses the point whether or not they can drain the large amounts of glycerol produced from biodiesel. The chapter addresses pros and cons of each use. The third chapter covers the main biotechnological processes of glycerol transformation. The fourth chapter thoroughly describes the main thermochemical processes to transform glycerol into commodities, products that will be further used in the chemical industry to produce polymers, for instance. The fifth chapter covers the production of glycerol derivatives of high added-value. The sixth chapter addresses the use of glycerol in the context of a biorefinery. The main idea is to show that many of the processes described in the previous chapters could be entirely green, using exclusively renewable raw materials.
