Research progress on synergistic conversion of coal/coal char and natural gas
摘要
Abstract
The synergistic conversion of coal and natural gas can help to achieve complementary carbon and hydrogen elements of the two energy resources and to achieve energy conservation and reduction of consumption,which has great value and significance for the development of an energy system based on coal with multi-energy integration.China is rich in low-rank coal resources,and with the development of coal classification and graded utilization industry via medium-low temperature pyrolysis,a large number of coal pyrolysis semi-coke(referred to as"coal char")is in urgent need of high-value conversion and utilization.Especially,the conversion of coal char is usually the decisive step of coal conversion,which limits its application paths to some extent.Based on the main characteristics of thermal conversion of coal and natural gas,the process features and the related works about synergistic conversion of coal and natural gas were briefly described,focusing on the research of synergistic conversion of coal char(as an intermediate of coal conversion)and natural gas for co-production of carbon materials and hydrogen/syngas.A comprehensive review was conducted from three aspects:Integrating coal char conversion and methane cracking,integrating coal char conversion and methane dry reforming,and synergistic conversion of coal char and coal pyrolysis gas obtained at medium-low temperature.The future development direction was also prospected.关键词
