Disclosed relates to the field of high gravity technology, and is a method for directly synthesizing a synthesis gas into a low-carbon olefin. The present method directly converts and synthesizes a synthesis gas into a low-carbon olefin with the effect of a catalyst and a high gravity environment. During the reaction process, a catalyst bed layer rotates at a certain rotational speed; the reaction material is a coal-based synthesis gas, natural gas-based synthesis gas, coal bed methane-based synthesis gas, or biomass-based synthesis gas; the high gravity of a high gravity reactor is from 2 to 400g, the reaction temperature is from 180°C to 500°C, the reaction pressure is from 1 to 100 atm, and the gas space velocity is from 100 to 100,000h -1 . The present invention can produce a targeted low-carbon olefin product, has good mass transfer performance and heat conductivity, and the catalyst thereof has a long service life. |
