This book was released on 2015 with total page 59 pages. Available in PDF, EPUB and Kindle. Book excerpt: Currently, energy has become the most demand for human needed. The utilization of future energy that is clean and sustainable becomes increasingly urgent because of dwindling petroleum reserves and mounting environmental concerns that are associated with fossil fuel. Hydrogen has been considered as the most suitable alternative for future energy aiming to reduce the dependence on fossil fuel and carbon based emission. Previously, non-renewable resources mainly coal, fossil fuel, petroleum coke, and petroleum residues has been widely used as the main feedstock for syngas (H2 and CO) production. However, due to the various factors such are global warming, the unstable price and availability of petroleum-based oil as well as the environmental pollution, the desirability towards biomass (glycerol) as the alternative energy feedstock has attract the world's attention. Glycerol which a by-product of biodiesel production is one of the most promising renewable sources associated environmental impacts from the usage of the fossil fuels in which it minimal carbon dioxide (CO2) emission and more preferable in fuels production. In recent years, the production of hydrogen from glycerol via steam reforming widely investigated, only a few studies on dry reforming with CO2. Therefore, this project was attempted to study the production of hydrogen via glycerol dry reforming over nickel (Ni) catalyst supported on silica oxide (SiO2) and alumina (Al2O3) modified with lanthanum (La). This works aims to synthesis, characterize, and screening Ni catalyst supported on SiO2 and Al2O3 with promoted in La solution using various techniques such are Scanning Electron Microscopy (SEM), X-Ray Diffraction (XRD) analysis , Mastersizer 2000 Ver.5.60 and elemental analysis. The catalyst characterization includes their porosity, structure, crystalline behaviour, and a physiochemical property is investigated. It shows that the promoted catalyst possessed smaller metal crystalline size, hence higher metal dispersion compared than both Ni/Al2O3 and Ni/SiO2 catalyst. In addition, the particle size distribution measured by Mastersizer measurement for promoted alumina catalyst gave higher size distribution which about 0.452 m2/g compared than silica oxides support. The reaction studies for syngas production at T=973 K for 3 hour reaction time with the inlet flowrate and carbon to to glycerol ratio is 0.03 ml/min and 1 had successfully produced H2 with glycerol conversion and H2 yield that peaked at 5.8% and 28% respectively over 3% La content. The catalyst screening shows that the alumina support gave excellent catalytic performance compared than silica oxide due to the larger surface area and smaller crystallite size that ensured accessibility of active catalytic area.

Download or read book Solid Base Catalysis written by Yoshio Ono and published by Springer Science & Business Media. This book was released on 2012-08-31 with total page 431 pages. Available in PDF, EPUB and Kindle. Book excerpt: The importance of solid base catalysts has come to be recognized for their environmentally benign qualities, and much significant progress has been made over the past two decades in catalytic materials and solid base-catalyzed reactions. The book is focused on the solid base. Because of the advantages over liquid bases, the use of solid base catalysts in organic synthesis is expanding. Solid bases are easier to dispose than liquid bases, separation and recovery of products, catalysts and solvents are less difficult, and they are non-corrosive. Furthermore, base-catalyzed reactions can be performed without using solvents and even in the gas phase, opening up more possibilities for discovering novel reaction systems. Using numerous examples, the present volume describes the remarkable role solid base catalysis can play, given the ever increasing worldwide importance of "green" chemistry. The reader will obtain an overall view of solid base catalysis and gain insight into the versatility of the reactions to which solid base catalysts can be utilized. The concept and significance of solid base catalysis are discussed, followed by descriptions of various methods for the characterization of solid bases, including spectroscopic methods and test reactions. The preparation and properties of base materials are presented in detail, with the two final chapters devoted to surveying the variety of reactions catalyzed by solid bases.
Book Synopsis Steam Reforming of Oxygenated Hydrocarbons for Hydrogen Production Over Metal Catalysts by : Sushil Adhikari
Download or read book Steam Reforming of Oxygenated Hydrocarbons for Hydrogen Production Over Metal Catalysts written by Sushil Adhikari and published by . This book was released on 2008 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: With the increase in production of biodiesel, a glut of glycerol has resulted in the world market. Glycerol, once a valuable chemical, has become a recalcitrant byproduct. It is also a potential renewable feedstock for hydrogen production. This study is focused on hydrogen production from glycerol steam reforming. During the initial stage, effect of process variables, such as system pressure (1-5 atm), temperature (327-727 °C) were calculated by the method of Gibbs free energy minimization. The study revealed that the best conditions for producing hydrogen is at temperature> 627 °C, atmospheric pressure, and water/glycerol molar ratio (WGMR) 9:1. As a part of catalysts screening, 14 catalysts were prepared on monoliths and tested for their activity. Effects of those catalysts on hydrogen selectivity and glycerol conversion in temperatures ranging from 600-900 °C were discussed. Ni/Al2O3 and Rh/CeO2/Al2O3 were found to be the best performing catalysts based on hydrogen selectivity and glycerol conversion under the conditions investigated in this study. Also, the effect of WGMR, metal loading, and feed flow rate (FFR) were analyzed for the two best performing catalysts. Subsequently, effect of CeO2, MgO, and TiO2 supported Ni catalysts on hydrogen production from glycerol was studied. Effects of reaction temperature, FFR, and WGMR on hydrogen selectivity and glycerol conversion were also analyzed. Ni/CeO2 was found to be the best performing catalyst when compared to Ni/MgO and Ni/TiO2 under the experimental conditions investigated. The activation energy of glycerol reforming reaction was found to be 103 kJ/mol, and the reaction order with respect to glycerol was 0.23 over Ni/CeO2 catalysts based on the power law.
