Problems solved by technology

Therefore, when using the above hydrocracking processes alone, you can only choose different types of hydrocracking catalysts according to your needs, or use two molecular sieve composite catalysts, or use two kinds of hydrocracking catalysts in grades, but these processes only It can produce tail oil products of one nature, that is, the operation flexibility is relatively poor

Abstract

The invention discloses a flexible hydrocracking process. A wax oil raw material is subjected to hydrogenation pretreatment and then enters a hydrocracking reactor, and the material passing through anupper hydrocracking catalyst bed layer is divided into two streams; one material stream is extracted out of the hydrocracking reactor through the middle of the bed layer and enters a hydroisomerization cracking reactor for an isomerization cracking reaction; the other material stream flows downwards through a hydrocracking catalyst bed layer at the lower part; and an obtained hydrocracking reaction material and an obtained hydroisomerization cracking reaction material are subjected to gas-liquid separation and fractionation separately to obtain naphtha, aviation kerosene, diesel oil and tailoil products with different specifications. The invention provides the hydrocracking process for simultaneously producing more than two different-specification light naphtha, heavy naphtha, aviation kerosene, diesel oil and tail oil products on one set of hydrogenation process equipment for the first time, heat carried by part of cracked materials can be fully utilized, and coupling operation of the hydrocracking reactor and the hydroisomerization cracking reactor can be realized.

Description

technical field [0001] The invention belongs to the field of petroleum refining, and in particular relates to a hydrocracking process for flexibly producing high-quality light naphtha, heavy naphtha, jet fuel, diesel oil and tail oil products with different properties. Background technique [0002] Hydrogenation technology is an important processing method for lightening heavy oil and upgrading the quality of light oil. Hydrocracking technology has developed rapidly due to the advantages of strong feed oil adaptability, good product flexibility, high liquid product yield, and high product quality. The existing hydrocracking technology can be divided into three types according to the processing flow: one-stage series hydrocracking process, single-stage hydrocracking process and two-stage hydrocracking process. According to whether the tail oil is recycled or not, it can be divided into three types: one-way one-pass process, partial cycle process and full cycle process. Hydr...
