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 hydrocracking process for flexibly producing diesel oil. After the wax oil raw material is pretreated by hydrogenation, it enters the hydrocracking reactor, and the obtained hydrocracking material is divided into two streams, one of which enters the hot high-pressure separator to separate the gas phase and liquid phase; the one that does not enter the high-pressure separator The hydrocracked material is mixed with the gas phase separated by the hot high-pressure separator for gas-liquid separation and fractionation to obtain hydrocracked naphtha, jet fuel, diesel oil and tail oil; the liquid phase separated by the hot high-pressure separator and / or After all the hydrocracking tail oil is mixed, continue to mix with hydrogen for hydroisomerization cracking reaction, and the hydroisomerization cracking material undergoes gas-liquid separation and fractionation to obtain hydroisomerization cracking naphtha, jet fuel, diesel oil and tail oil . The invention provides for the first time a hydrocracking process for simultaneously producing more than two types of jet fuel, diesel oil and tail oil products of different specifications, especially diesel oil with different freezing points, on a set of hydrogenation process equipment.

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 naphtha, jet fuel, diesel oil and tail oil products of different properties from wax oil. 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. Hydrocracking ...
