Document Type and Number:
WIPO Patent Application WO/2022/083714
Kind Code:
A1
Abstract:
Provided are a multi-phase combination reaction system and reaction method. The system comprises at least one fixed bed hydrogenation reactor. The fixed bed hydrogenation reactor comprises, arranged from top to bottom, a first hydrogenation reaction area, a gas-liquid separation area, a second hydrogenation reaction area, and a third hydrogenation reaction area. The gas-liquid separation area is provided with a raw oil inlet. A hydrogen inlet is provided between the second hydrogenation reaction area and the third hydrogenation reaction area. The present system and method are capable of simultaneously obtaining two fractions in one hydrogenation reactor, which are used for gasoline, diesel products, aviation kerosene products, ethylene raw materials, etc., and are also capable of preventing flooding in the hydrogenation reactor.
