Book Description
Natural-gas fuelled catalytic heaters are commonly used in heating industrial space and remote location operations. Industrial units typically contain platinum that provides methane combustion at lower temperatures than non-catalytic burning. This work aimed to find a cost-efficient alternative to monometallic platinum catalyst by replacing some of platinum with less expensive palladium, which is also known for methane combustion activity. The task is complicated by non-uniform reactant profiles across the catalytic pad. Several Pd:Pt bimetallic catalysts were prepared by dry impregnation of commercial pads with metal precursors and tested in methane combustion with 5% water presence at two different methane-to-oxygen molar ratios (0.2 and 0.02). Pt1.6Pd catalyst (molar ratio) is recommended to replace monometallic platinum: it provides higher activity than monometallic Pt catalyst at 0.02 CH4-to-O2 ratio. At the 0.2 ratio, its activity is lower than that of Pt, but is sufficient for adequate heater operation.

Book Description
The increase of greenhouse gases in the atmosphere and the decrease of the available amount of fossil fuels necessitate finding new alternative and sustainable energy sources in the near future. This book summarizes the role and the possibilities of catalysis in the production of new energy carriers and in the utilization of different energy sources. The main goal of this work is to go beyond those results discussed in recent literature by identifying new developments that may lead to breakthroughs in the production of alternative energy. The book discusses the use of biomass or biomass derived materials as energy sources, hydrogen formation in methanol and ethanol reforming, biodiesel production, and the utilization of biogases. Separate sections also deal with fuel cells, photocatalysis, and solar cells, which are all promising processes for energy production that depend heavily on catalysts.

Book Description
Climate change is an issue that is highly debated around the globe. This book brings together the papers that were presented at a conference dedicated to this issue, held in Kyoto in October 2002. Covering a broad range of areas, the topics presented will benefit both those working in the field of carbon dioxide recovery and sequestration, and those looking at the effects of non carbon dioxide greenhouse gases. An overview of the Research and Design technologies which aid in mitigating climate change is included, which will be invaluable to those researching new opportunities for dealing with this problem. An area of research that has seen a rapid rise in worldwide spend Will benefit both researchers in climate change, and those looking at new technologies to help deal with the problem Presents papers from contributors spread around the globe means that this book has world wide relevance

Book Description
The increasing demand for energy and the related environmental concerns are the main drivers for the strong interest in Biomass Fermentation towards usage in Fuel Cells. The integration of Biomass Fermentation (BF) and Fuel Cells (FC) technology creates a new and interdisciplinary research area. Due to their high efficiency Fuel Cells are therefore considered as a strategic technology for future energy supply systems. The fact that biomass is a renewable source of energy in combination with the most efficient energy conversion system (FC) makes this combination unique and advantageous. This book has a clear orientation towards making products of our waste. Biofuels for Fuel Cells comes at a time when this field is rapidly developing and there is a need for a synthetising book. The holistic and multidisciplinary description of this topic, including discussion of technological, socio-economic, system analysis and policy and regulatory aspects, make this book the definitive work for this market. Biofuels for Fuel Cells will cross-link scientists of all fields concerned with Biomass Fermentation, Fuel Upgrading and Fuel Cells at European and World level.

Book Description
Coal, still used to generate more than half of the electric power in the U.S., will likely be part of any future global energy plan. But this finite resource is also responsible for 80 percent of the CO2 emissions from power production, and its continued use will require improved processing techniques that are less damaging to the environment and l

Book Description
This book examines the issues on noble metal influence on gaseous combustion. The book focuses on the new data on combustion processes having practical applications and includes fire safety issues in the use of noble metals in hydrogen recombiners for NPP, as well as in catalytically stabilized (CS) combustion technology including stimulation of combustion of hydrogen-blended hydrocarbons, synthesis of carbon nanotubes, and determination of catalytic ignition limits in noble metal-hydrogen-hydrocarbon systems to meet the challenges of explosion safety.

Book Description
This proceedings volume comprises the invited plenary lectures, contributed and poster papers presented at a symposium organised to mark the successful inauguration of the world's first commercial plant for production of gasoline from natural gas, based on the Mobil methanol-to-gasoline process. The objectives of the Symposium were to present both fundamental research and engineering aspects of the development and commercialization of gas-to-gasoline processes. These include steam reforming, methanol synthesis and methanol-to-gasoline. Possible alternative processes e.g. MOGD, Fischer-Tropsch synthesis of hydrocarbons, and the direct conversion of methane to higher hydrocarbons were also considered.The papers in this volume provide a valuable and extremely wide-ranging overview of current research into the various options for natural gas conversion, giving a detailed description of the gas-to-gasoline process and plant. Together, they represent a unique combination of fundamental surface chemistry catalyst characterization, reaction chemistry and engineering scale-up and commercialization.
