Download Catalytic Co-conversion of Glycerol and Proton-donor Species to Gasoline-range Aromatics Over Alumina Book in PDF, ePub and Kindle
Glycerol is the main by-product of the biodiesel production process. Saturation of this by-product in the market would negatively affect the growth of biodiesel production industry. Due to complexities in the purification processes of crude-glycerol, less costly chemical conversion of glycerol to value-added products and feedstocks such as propenal and aromatics has gained more attention recently. In this work, the influence of co-feeding proton-donor and olefin-donor species on the catalytic conversion of glycerol over alumina catalyst to gasoline-range aromatics is studied. During the individual catalytic conversion of glycerol over alumina, because of the shortage of proton-donor intermediates in the process and high activity of glycerol on alumina at 470°C, glycerol mostly leads to form high carbon deposit content and aqueous phase stream, but less liquid organic production. Introducing methanol and ethanol as compound models of alcohols, and dodecane and hexadecane as compound models of long-chain alkanes next to glycerol remarkably decreases the formation of undesired stream, while selectivity to aromatics substantially increases. In terms of liquid aromatics generation and restricting the excessive carbonization on the catalyst surface, co-feeding 25 wt.% hexadecane with 75 wt.% glycerol has the highest efficiency among the selected compound models; with increasing the liquid aromatics selectivity from 17.7% to 42.5%. Additionally, Co-processing the latter compound model, noticeably shifts the distribution of produced aromatics from heavy undesired aromatics range to the gasoline-range aromatics such as xylenes and toluene. The potential influence of hexadecane on the glycerol to aromatics reaction pathway over alumina catalyst is also proposed, and the effective reactions between glycerol and hexadecane intermediates are discussed. It is also found that selecting a very high or low operational temperature would inversely affect the optimization of aromatics formation through the co-processing runs of glycerol and hexadecane.

Download Hydrogen Transfer Reactions Book in PDF, ePub and Kindle
The series Topics in Current Chemistry Collections presents critical reviews from the journal Topics in Current Chemistry organized in topical volumes. The scope of coverage is all areas of chemical science including the interfaces with related disciplines such as biology, medicine and materials science. The goal of each thematic volume is to give the non-specialist reader, whether in academia or industry, a comprehensive insight into an area where new research is emerging which is of interest to a larger scientific audience. Each review within the volume critically surveys one aspect of that topic and places it within the context of the volume as a whole. The most significant developments of the last 5 to 10 years are presented using selected examples to illustrate the principles discussed. The coverage is not intended to be an exhaustive summary of the field or include large quantities of data, but should rather be conceptual, concentrating on the methodological thinking that will allow the non-specialist reader to understand the information presented. Contributions also offer an outlook on potential future developments in the field.

Download The Role of Catalysis for the Sustainable Production of Bio-fuels and Bio-chemicals Book in PDF, ePub and Kindle
The Role of Catalysis for the Sustainable Production of Bio-fuels and Bio-chemicals describes the importance of catalysis for the sustainable production of biofuels and biochemicals, focused primarily on the state-of-the-art catalysts and catalytic processes expected to play a decisive role in the "green" production of fuels and chemicals from biomass. In addition, the book includes general elements regarding the entire chain of biomass production, conversion, environment, economy, and life-cycle assessment. Very few books are available on catalysis in production schemes using biomass or its primary conversion products, such as bio-oil and lignin. This book fills that gap with detailed discussions of: Catalytic pyrolysis of lignocellulosic biomass Hybrid biogasoline by co-processing in FCC units Fischer-Tropsch synthesis to biofuels (biomass-to-liquid process) Steam reforming of bio-oils to hydrogen With energy prices rapidly rising, environmental concerns growing, and regulatory apparatus evolving, this book is a resource with tutorial, research, and technological value for chemists, chemical engineers, policymakers, and students. Includes catalytic reaction mechanism schemes and gives a clear understanding of catalytic processes Includes flow diagrams of bench-, pilot- and industrial-scale catalytic processing units and demonstrates the various process technologies involved, enabling easy selection of the best process Incorporates many tables, enabling easy comparison of data based on a critical review of the available literature

This monograph consists of the proceedings of the Fifth International Symposium on the Activation of Dioxygen and Homogeneous Catalytic Oxidation, held in College Station, Texas, March 14-19, 1993. It contains an introductory chapter authored by Professors D. H. R. Barton and D. T. Sawyer, and twenty-nine chapters describing presentations by the plenary lecturers and invited speakers. One of the invited speakers, who could not submit a manuscript for reasons beyond his control, is represented by an abstract of his lecture. Also included are abstracts of forty-seven posters contributed by participants in the symposium. Readers who may wish to know more about the subjects presented in abstract form are invited to communicate directly with the authors of the abstracts. This is the fifth international symposium that has been held on this subject. The first was hosted by the CNRS, May 21-29, 1979, in Bendor, France (on the Island of Bandol). The second meeting was organized as a NATO workshop in Padova, Italy, June 24-27, 1984. This was followed by a meeting in Tsukuba, Japan, July 12-16, 1987. The fourth symposium was held at Balatonfured, Hungary, September 10-14, 1990. The sixth meeting is scheduled to take place in Delft, The Netherlands (late Spring, 1996); the organizer and host will be Professor R. A. Sheldon.
