Research Progress on Influence of Reaction Atmosphere on Pyrolysis Process of Oil Shale
China's oil shale resources are extremely rich.At present,shale oil and pyrolysis gas are mainly produced by oil shale pyrolysis to realize resource utilization of oil shale.The essence of oil shale pyrolysis is the pyrolysis process of kerogen and inorganic minerals,including the primary reaction of kerogen and inorganic mineral decomposition,and the secondary reaction of asphaltene cracking and carbon residue polycondensation.The reaction mechanism is very complex,involving pyrolysis,polycondensation,dehydrogenation,hydrogenation,isomerization and other reactions.Therefore,the pyrolysis process of oil shale is affected by many factors such as reaction atmosphere,pyrolysis temperature,pyrolysis time,heating method and catalyst.Among them,the reaction atmosphere can greatly change the distribution and characteristics of oil shale pyrolysis products,such as shale oil yield and content of light components,thus affecting the utilization efficiency of oil shaleresources.To this end,the research status of the influence of reaction atmospheres such as H2,CO2,N2,ethanol and water vapor on the pyrolysis process of oil shale was elaborated,which provided new ideas and explored new ways to improve the yield and quality of oil shale pyrolysis products and further improve the comprehensive utilization value of oil shale resources.
