With CO ₂ As Raw Material Entrained Flow Gasification Of High Concentration CO Syngas Research

Scientific research shows that, the earth’s temperature gradually increased due to the large number of emissions of greenhouse gases in recent years, the ecological environment of the earth suffered catastrophic destruction. Carbon dioxide is a harmful greenhouse gas, is also a valuable resource. At present, Carbon dioxide is widely used in food preservation, CO2flooding, CO2gas shielded welding and chemical synthesis and other fields, and achieved good economic benefit. But compared with the growing capacity of carbon dioxide, the amount of carbon dioxide for the production consumption accounted for only a small part of total output each year, large amounts of carbon dioxide cannot be fully utilized and emissions into the atmosphere, further intensify the greenhouse effect. No matter from protect environment or rational utilization of resources, Development more of carbon dioxide utilization technologyis is imperative. The utilization of carbon dioxide as raw material for the production of synthesis gas of high concentration of carbon monoxide, is a new technology development from entrained flow gasification for using carbon dioxide,this technology can be continuous and large-scale use of carbon dioxide.Entrained flow gasification to produce high concentrations of carbon monoxide synthesis gas process is carbon dioxide and oxygen mixture as gasifying agent,hydrocarbon substances as raw material, such as coal, coke, petroleum coke. The gasifying agent and gasification cocurrent flow to enter the reactor to generate high concentrations of carbon monoxide synthesis gas. The paper studies on the entrained flow gasification syngas high concentration of carbon monoxide, studied emphatically from the gasification reaction principle, gasification and gasification test, exploration Entrained Flow Gasification Production Syngas high concentrations of carbon monoxide.With traditional oxygen, steam for the production of synthesis gas gasification agent than,using carbon dioxide and oxygen mixture for the production of synthesis gas gasifying agent, Effective gas content in synthesis gas is increased by1-2%, The ratio of coal consumption, oxygen consumption index decreased.
