Problems solved by technology

However, these methods do not focus on how to obtain high-octane gasoline; or require the addition of conventional petroleum components, which destroy the cleaning properties of Fischer-Tropsch oils
[0007] From the prior art disclosed in this field, the processing about the Fischer-Tropsch synthetic oil product mainly concentrates on the process of producing gasoline by the Fischer-Tropsch synthetic oil product or producing light olefins by the Fischer-Tropsch synthetic oil product. There are few reports on the co-production of low-carbon olefins in the process of producing gasoline from oil products

Abstract

The invention provides a method for co-producing high-octane gasoline and low-carbon olefin from a Fischer-Tropsch synthesis oil product, and a device for implementing the method. Specifically, the method comprises the following steps: feeding a Fischer-Tropsch synthesis oil product in two parallel reactors respectively, carrying out catalytic cracking and aromatization reaction on the Fischer-Tropsch synthesis oil product in a first reactor, carrying out catalytic cracking reaction on the Fischer-Tropsch synthesis oil product in a second reactor, carrying out settling separation on the obtained product, and carrying out fractionation to co-produce the high-octane gasoline and the low-carbon olefin at the high yield,. The feeding of the two reactors can be flexibly adjusted according to requirements, and the low-carbon olefin content can be effectively increased through the cyclic utilization of the regenerated high-temperature regeneration catalyst. The process method adopted by the invention is simple, and good economic benefits can be realized.
