Technological process for technology of preparing coal chemical chain oxygen carrier to synthesis gas

The invention discloses a technological process for a technology of preparing a coal chemical chain oxygen carrier to synthesis gas. In the process, coal is not directly contacted with air; vapor is adopted as a fluidization and gasification medium; the transfer of oxygen and heat is realized through the circular conversion of oxygen carrier particles between a gasification furnace R1001 and a regeneration furnace R1002; then the gasification reaction of not contacting the coal dust with the air is finished. Main equipment of the complete technological process comprises the gasification furnace R1001, the regeneration furnace R1002, a return valve L1001, cyclone separators (X1001, X1002), afterheat recoverers (E1001, E1002) and the like. The process avoids or reduces the conversion of sulfur in the coal to sulfurous gas, and decreases the emission of Sox. The technology of preparing the coal chemical chain oxygen carrier to the synthesis gas adapts to coal types with high sulfur, high ash specification and hi
