Description

technical field [0001] The present invention relates to a kind of method of selective regulation and control Fischer-Tropsch synthesis product, specifically, relate to a kind of method that utilizes supergravity reactor to carry out Fischer-Tropsch synthesis under supergravity condition, comprise directional synthesis olefin, alkyne, gasoline, diesel oil , paraffin, mixed alcohol and other products. Background technique [0002] Fischer-Tropsch synthesis (Fischer-Tropsch process), also known as F-T synthesis, is based on synthesis gas (CO, CO 2 and H 2 The mixed gas) is used as the raw material to synthesize the paraffin-based liquid fuel process under the catalyst and appropriate conditions. The traditional Fischer-Tropsch synthesis products are mainly linear alkanes, olefins, a small amount of aromatics and aldols, as well as by-products of water and carbon dioxide. The product composition is complex, the selectivity is poor, and there are few light liquid hydrocarbons. ...
