Entrained-flow pulverized coal hydrogasification method

An embodiment of the invention provides an entrained-flow pulverized coal hydrogasification method, belongs to the field of coal gasification, and can stably realize the coal hydrogasification process, obtain high-quality products and realize efficient utilization of coal resources. The entrained-flow pulverized coal hydrogasification method comprises steps as follows: pulverized coal and heated feed gas are mixed and then sent into a gasifier through a gasifier nozzle; the pulverized coal and the heated feed gas are mixed at a reaction section of the gasifier and have a hydrogasification reaction to produce semi-coke, synthesis gas and gaseous oil; the synthesis gas and the gaseous oil are subjected to dust removal and heat exchange after cooled by a cooling device at an outlet of the reaction section, and a gaseous product and a liquid oil product are obtained; the semi-coke is discharged out of the gasifier. The method can be applied to the coal hydrogasification process.
