Method for making gas, supplementing carbon and increasing methanol yield by chopped coke with 7-24mm

The invention belongs to the technical field of comprehensive utilization of coke-oven gas, and concretely relates to a method for making gas, supplementing carbon and increasing methanol yield by chopped coke with 7-24mm. By aiming the component characteristic of coke-oven gas, the disadvantages that hydrogen component utilization is insufficient in prior art can be solved, by combing real condition of good quality, low price and difficult sale of self-produced 7-24 chopped coke in a coking enterprise, production flow can be improved and optimized, and full utilization of the effective component of the coke-oven gas can be realized. The rich H2 in the coke-oven gas is taken as a reference for supplying carbon source, the self-produced chopped coke with 7-24 mm in the coking enterprise is taken as a raw material, a continuous oxygen-rich normal pressure gas making furnace is used for producing gas, a gas purifying processing system is cooperated, methanol production capability in current enterprise is increas
