The present invention discloses a thermal plasma coal cracking-gasification coupling process and reaction unit, which pertains to the technical field of coal chemical industry. The present invention introduces a fast gas-solid separator and coal gasification reactor behind the plasma coal cracking reaction unit. This unit may realize the coupling of plasma coal cracking and coal gasification, comprehensively utilizes the high-level energy in gas cooling stage, particularly the high level energy of coal powder, forms a large amount of gaseous byproducts and raises the overall conversion rate of coal and the comprehensive value of the process. The present invention may make full use of the high-level energy carried by the reaction products during plasma coal cracking, particularly the post-reaction coal powder, increases the reaction time and course of coal powder, may increase the overall conversion rate of coal, and obtain the gaseous byproducts like CO and H2 from the added coal gasification reactor during c
