Catalytic conversion method for directly processing high chlorine raw material

Abstract

The present invention relates to a catalytic conversion method for directly processing a high chlorine raw material. The method comprises that a pre-heated high chlorine raw material and a first catalytic conversion catalyst are subjected to a first contact reaction to make the chlorine-containing compound in the high chlorine raw material be adsorbed on the first catalytic conversion catalyst and decompose less than or equal to 30% by weight of the chlorine-containing compound to obtain a first contacting product; and the first contacting product and a second catalytic conversion catalyst are subjected to a second contact reaction to remove the chlorine-containing compound, wherein the reaction temperature of the second contact reaction is higher than the reaction temperature of the first contact reaction. With the method of the present invention, the high chlorine raw material can be directly processed while the high dechlorination rate can be obtained, the high chlorine raw material conversion rate can be improved, the product selectivity can be improved, and the dry gas yield and the coke yield can be reduced.

Description

Technical field

[0001] The invention relates to a method for catalytic conversion of hydrocarbon oil, in particular to a method for catalytic conversion of directly processing high-chlorine raw materials. Background technique

[0002] my country’s oil resources are relatively short. In 2012, the Swiss Bank released a report on the status of the global oil sector. China’s oil reserves are about 15 billion barrels, accounting for 1.1% of the world’s oil reserves, which is only enough for 10 years. The deterioration of crude oil has become more and more serious around the world. Especially in the past ten years, water injection has been the mainstay. The application of multiple oil extraction technologies has made the composition of crude oil and reinjected water complicated, which not only caused difficulties in the treatment of crude oil and sewage, but also The stable operation of oil refining equipment, equipment corrosion, and product quality have serious impacts. Among them, c...
