![]() ![]() The operating temperature, residence time and type of feedstock are other factors that can also affect the gas yield and quality. Introducing a catalyst to these processes increases the rate reactions and hence the number of successful reactions. The concentration of each component affects the rate of reaction for each product. These processes contribute to complex kinetics of the overall process involving a series of reactions, including: CO + H2O ͍ CO2 + H2, CO + 3H2 → CH4 + H2O, C + H2O → CO + H2, CH4 + 2H2O → CO2 + 4H2, CO2 + 4H2 → CH4 + 2H2O, C + 2H2O → 2H2 + CO2, CO + 2H2 → CH3OH, C + CO2 → 2CO, 2C + H2 → C2H2, & C + 2H2 → CH4. Steam gasification and reforming of tar involves thermal decomposition of tar and the reaction of tar with steam and fuel gases. This study focuses on catalytic destruction of tar in a hot gas stream, at different operating conditions to improve the gas yield and quality. Tar is one of the major impurities found in streams, and can foul and block equipment. ![]() ![]() The fuel gas often requires cleaning and upgrading ahead of combustion in advanced technologies such as gas engines, fuel cells and turbines. Thermal conversion of organic materials through gasification yields gaseous fuel. ![]()
