Oxygen-enriched Gasification Process Used 5A Molecular Sieve

Oxygen-enriched gasification is a thermochemical process of coal. It is a process that uses coal or coal coke as raw materials and oxygen (air, oxygen-enriched or industrial pure oxygen) as a gasifying agent to convert the combustible part of coal or coal coke into combustible gas through chemical reactions under high temperature and pressure. The combustible gas obtained during gasification becomes coal gas. The coal gas used as a chemical raw material is generally called synthesis gas (in addition to coal as raw material, synthesis gas can also use natural gas, heavy petroleum components, etc. as raw materials). The equipment for gasification is called a gasifier or gasifier. According to the characteristics of different components and different reaction stages of coal, the implementation of coal pyrolysis, gasification, and combustion staged conversion can simplify coal gasification technology and effectively solve the problem of removing pollutants in coal. Based on the idea of ​​staged conversion, Zaozhuang bituminous coal was used as the main raw material on a small fluidized bed test bench to study the effects of oxygen concentration and air-coal ratio on the gasification process, and compared and analyzed the results with air gasification, which can provide a theoretical basis for studying partial coal gasification and semi-coke combustion integration.
