Book excerpt: Fischer-Tropsch (FT) synthesis converts syngas into liquid hydrocarbons over cobalt catalyst for new ultraclean alternative fuels. The syngas can be produced from both fossil and renewable resources. The catalysts for FT synthesis are currently prepared by chemical ways like impregnation etc. All these routes involve toxic solvents and high temperature retreatment. Because of lower cost, reduced energy requirements and environmental pollution, the mechano-chemistry has a number of advantages for the synthesis of heterogeneous catalysis compared to conventional techniques. In this study, the mechano-chemical method was used to prepare alumina supported cobalt catalysts for FT synthesis. Differently to the conventional catalyst preparation, the deposition of active phase did not involve any solvent in the proposed method. The goal of this work is to obtain efficient FT catalysts and to simplify catalyst synthesis by reducing the number of preparation steps. The project involves innovative method of synthesis of catalysts in three different mechanical working processes in dry context. The process of mechano-chemistry to synthesize the catalyst for FT reaction was developed. The operating conditions for the control of the coating technique were identified through optimal conditions study by statistical analysis. Moreover, characterizations were studied to understand the basic mechanisms behind deposition of particles on the interface. Catalytic performance tests were estimated in a mili-fixed bed reactor; Optimization algorithm of parameters in a mechanical process was carried out via deriving target formula about energy and material size.

Available in PDF, EPUB and Kindle. Book excerpt: The goal of the proposed work is the development of iron-based Fischer-Tropsch catalysts that combined high activity, selectivity and life with physical robustness for slurry phase reactors that will produce either low-alpha or high-alpha products. The catalyst that is developed will be suitable for testing at the Advanced Fuels Development Facility at LaPorte, Texas or similar sized plant. Previous work by the offeror has produced a catalyst formulation that is 1.5 times as active as the 'standard-catalyst' developed by German workers for slurry phase synthesis. The proposed work will optimize the catalyst composition and pretreatment operation for this low- alpha catalyst. In parallel, work will be conducted to design a high- alpha iron catalyst that is suitable for slurry phase synthesis. Studies will be conducted to define the chemical phases present at various stages of the pretreatment and synthesis stages and to define the course of these changes. The oxidation/reduction cycles that are anticipated to occur in large, commercial reactors will be studied at the laboratory scale. Catalyst performance will be determined for 5 catalysts synthesized in this program for activity, selectivity and aging characteristics.

Download or read book Technology Development for Iron and Cobalt Fischer-Tropsch Catalysts written by and published by . This book was released on 1999 with total page 86 pages. Available in PDF, EPUB and Kindle. Book excerpt: The simple polymerization mechanism for the Fischer-Tropsch synthesis produces products which follows an Anderson-Schulz-Flory distribution. Thus, plotting the logarithm of the mole fraction versus carbon number will produce a straight line whose slope is related to alpha which is determined by the chain termination and propagation probabilities. In contrast, the products from laboratory and large commercial plants exhibit a two-alpha plot. Vapor-liquid calculations show that product accumulation cannot be responsible for the two-alpha plot when the alpha value is large enough to produce liquid products at the reaction temperature. Only in the case where alpha is small and all products are in the vapor phase, allowing evaporation of the startup solvent and a drying out of the reactor can a product accumulation produce a two-alpha plot. Results of filtration successes and failures from runs with the CSTR are described.

This book was released on 2007-10-31 with total page 119 pages. Available in PDF, EPUB and Kindle. Book excerpt: Waste minimisation has a number of aims which include enhancing the intrinsic selectivity of any given process, providing a means of recovering reagents in a form which allows easy regeneration and the replacement of stoichiometric processes with catalytic ones. Solids, as catalysts or as supports for other reagents, offer potential for benefit in all these areas. This monograph provides an overview of the properties of the more useful solid catalysts and supported reagents, and highlights their most valuable applications in the preparation of organic chemicals in liquid phase reactions. Clean Synthesis Using Porous Inorganic Solid Catalysts and Supported Reagents is concerned with the use of solid catalysts in the clean synthesis of organic chemicals. The emphasis is on chemical processes of importance to the manufacture/preparation of fine and speciality chemicals, chemical intermediates and pharmaceutical intermediates, especially where catalysis is not currently used or where current catalysts are homogeneous, leading to difficult separation procedures and unacceptable levels of waste. This book focuses on solid catalysts based on inorganic supports and covers the emerging area of chemically modified mesoporous solid catalysts.

This book was released on 2012-04-16 with total page 324 pages. Available in PDF, EPUB and Kindle. Book excerpt: For far too long chemists and industrialists have relied on the use of aggressive reagents such as nitric and sulphuric acids, permanganates and dichromates to prepare the massive quantities of both bulk and fine chemicals that are needed for the maintenance of civilised life — materials such as fuels, fabrics, foodstuffs, fertilisers and pharmaceuticals. Such aggressive reagents generate vast quantities of environmentally harmful and often toxic by-products, including the oxides of nitrogen, of metal oxides and carbon dioxide.Now, owing to recent advances made in the synthesis of nanoporous solids, it is feasible to design new solid catalysts that enable benign, mild oxidants to be used, frequently without utilising solvents, to manufacture the products that the chemical, pharmaceutical, agro- and bio-chemical industries require. These new solid agents are designated single-site heterogeneous catalysts (SSHCs). Their principal characteristics are that all the active sites present in the high-area solids are identical in their atomic environment and hence in their energy of interaction with reactants, just as in enzymes.Single-site heterogeneous catalysts now occupy a position of growing importance both academically and in their potential for commercial exploitation. This text, the only one devoted to such catalysts, dwells both on principles of design and on applications, such as the benign synthesis of nylon 6 and vitamin B3. It equips the reader with unifying insights required for future catalytic adventures in the quest for sustainability in the materials used by humankind.Anyone acquainted with the language of molecules, including undergraduates in the physical and biological sciences, as well as graduates in engineering and materials science, should be able to assimilate the principles and examples presented in this book. Inter alia, it describes how clean technology and ‘green’ processes may be carried out in an environmentally responsible manner.

Book excerpt: There is a strong national interest in the Fischer-Tropsch synthesis process because it offers the possibility of making liquid hydrocarbon fuels from reformed natural gas or coal and biomass gasification products. This project explored a new approach that had been developed to produce active, attrition-resistant Fischer-Tropsch catalysts that are based on glass-ceramic materials and technology. This novel approach represented a promising solution to the problem of reducing or eliminating catalyst attrition and maximizing catalytic activity, thus reducing costs. The technical objective of the Phase I work was to demonstrate that glass-ceramic based catalytic materials for Fischer-Tropsch synthesis have resistance to catalytic deactivation and reduction of particle size superior to traditional supported Fischer-Tropsch catalyst materials. Additionally, these novel glass-ceramic-based materials were expected to exhibit catalytic activity similar to the traditional materials. If successfully developed, the attrition-resistant Fischer-Tropsch catalyst materials would be expected to result in significant technical, economic, and social benefits for both producers and public consumers of Fischer-Tropsch products such as liquid fuels from coal or biomass gasification. This program demonstrated the anticipated high attrition resistance of the glass-ceramic materials. However, the observed catalytic activity of the materials was not sufficient to justify further development at this time. Additional testing documented that a lack of pore volume in the glass-ceramic materials limited the amount of surface area available for catalysis and consequently limited catalytic activity. However, previous work on glass-ceramic catalysts to promote other reactions demonstrated that commercial levels of activity can be achieved, at least for those reactions. Therefore, we recommend that glass-ceramic materials be considered again as potential Fischer-Tropsch catalysts if it can be demonstrated that materials with adequate pore volume can be produced. During the attrition resistance tests, it was learned that the glass-ceramic materials are very abrasive. Attention should be paid in any further developmental efforts to the potential for these hard, abrasive materials to damage reactors.
