The invention discloses a method for preparing low-carbon olefins from synthetic gas, and belongs to the field of olefins. In order to solve the problems that due to a backmixing phenomenon, the retention time is inconsistent, reaction products are widely distributed, and side reactions of olefin secondary reaction and water gas reaction and the like are intensified so as to influence the economy of the process in the traditional process for preparing low-carbon olefins from synthetic gas, a rotating packed bed reactor is used as a reactor, a solid Fischer-Tropsch synthesis catalyst is used or a catalyst is prepared into slurry, and the synthetic gas is converted into the low-carbon olefins. By the method, the selectivity of the low-carbon olefins can be greatly improved, and reaction heat can be quickly removed to stabilize the temperature of a reaction bed. |
