Release of gaseous products in oil shale pyrolysis by microwave heating
摘要
Abstract
The release of gaseous products in oil shale pyrolysis by microwave heating was investigated in a microwave heating test device. The effects on release of gaseous products in oil shale pyrolysis by microwave heating with different microwave powers from 30 percent to 80 percent of 1600W,heating temperature from 773K to 1173K,different pyrolysis temperature stages and different catalysts were studied. Microwave heating enhanced the release of H2,CO and C2H4. The release amount of hydrocarbons had a maximum at 50 percent microwave power of 1600W. A large amount of pyrolysis gas released at low temperature from 423K to 623K came from release of adsorbed gas and breakage of unstable branches and groupes. With increasing temperature,more gas was released from dehydrogenation,aromatization,condensation and free radical reaction of organic matter. Catalysts promoted gas release. However,different catalysts had different effects on pyrolysis gas composition. adsorption of molecular sieve (5A and 13X) promoted secondary decomposition and polymerization of organic matter. Clay catalysts (bentonite and activated clay) enhanced catalytic hydrogenation of organic matter under proton acid,sped up breakage of organic chains and improved groups stability.Metal catalysts (MoS2,FeS and Ni2O3) firstly increased heating rate and enhanced pyrolysis,secondly, promoted generation and transfer of hydrogen free radicals.关键词
