INTEGRATED CATALYTIC CRACKING PROCESS WITH LIGHT OLEFIN UPGRADING

摘要

There is provided a fluid catalytic cracking (FCC) process in which olefinic light gas produced in the FCC reactor unit (2), is separated from the FCC unit effluent (8). The separated light gas is then upgraded in a catalytic reactor (40) to increase gasoline production. By-product light parafinic gas (56) from reactor unit (40) is recycled to the FCC reactor as a lift gas (18).
