Abstract

Disclosed is a process for oriented synthesis of gasoline and diesel by Fischer-Tropsch synthesis. The process belongs to the field of supergravity technology. The process consists in performing oriented synthesis of a syngas into gasoline or diesel under the combined action of a supergravity environment and a catalyst; during the reaction, the catalyst bed is rotated at a certain rotation speed; the reaction materials are coal-based syngas, natural gas-based syngas, coal bed gas-based syngas or biomass-based syngas; the supergravity level of the supergravity reactor is 20-300 g; the reaction temperature is 180°C-500°C; the reaction pressure is 5-100 atm; and the space velocity of the gas is 100-100000h-1. The process of the present invention has the features of oriented production of gasoline and diesel products, good mass-transfer and heat-transfer performance, and long service life of the catalyst.

Description

technical field [0001] The invention relates to a method for directional synthesis of gasoline and diesel by Fischer-Tropsch synthesis, in particular to a method for directional synthesis of gasoline or diesel by using a high-gravity reactor in a high-gravity environment and under the action of a catalyst. 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. [0003] The Fischer-Tropsch synthesis reaction has a history of more than 80 years, and Sasol,...
