Problems solved by technology

This method is to hydrocrack all the coking distillate oil, which has a great influence on the yield of diesel oil. At the same time, the whole coking fraction, especially the distillate, contains more olefins and diolefins, and it is carried out at a higher temperature. During hydrocracking, these components are easy to coke, which affects the stable operation of the production unit

Embodiment 1-4 and comparative example 1

[0028] See the flowchart of Examples 1 to 4 figure 1 , The comparative example is that the coking whole distillate raw material directly enters the hydrorefining reaction zone without fractionation. The hydrorefining catalyst is filled with a hydrogenation protective agent, and its filling volume is 20% of the volume of the hydrorefining catalyst. The subsequent process is the same figure 1 .

[0029] The hydrorefining catalyst used in the examples and comparative examples is FH-98 (FH-98 is the catalyst grade) produced by the Wenzhou Catalyst Plant developed by Fushun Petrochemical Research Institute, and the hydrocracking pretreatment catalyst is Fushun Petrochemical Research Institute Developed 3996 (3996 is the catalyst grade) produced by Fushun Petrochemical Company Catalyst Plant. The hydrogenation protective agent is FZC-102 (FZC-102 is the catalyst grade) produced by the pilot base of Fushun Petrochemical Research Institute. The hydrogenation protective agent is filled i...

Abstract

This invention discloses a method for processing whole fraction oil of coking. The method comprises: separating whole fraction of coking into light fraction oil of coking (containing part of light diesel oil fraction) and heavy fraction oil of coking (containing heavy diesel oil fraction), hydrogenation-cracking heavy fraction oil of coking, hydrogenation-refining light fraction oil of coking, and separating the products in the same fractionation system. The method can obtain high-yield and high-quality clean diesel oil and naphtha, and has such advantages as simple process and low energy consumption.

Description

Technical field [0001] The present invention relates to a method for processing coking full distillate oil, in particular to a method for processing coking full distillate oil using a combined hydrogenation process, which is used to produce heavy naphtha and diesel products. The produced heavy naphtha can be used as high-quality catalytic heavy oil. The whole raw material, the obtained diesel product has low sulfur and nitrogen content, high cetane number, and good storage stability. Background technique [0002] At present, the international and domestic crude oil has a tendency to become heavier and deteriorate faster, and the range of oil fields involved is becoming wider and wider. In addition to the continuous development of the world economy and the increasingly stringent environmental regulations, it is necessary to produce a large number of light clean fuels. All these require the improvement and improvement of the existing oil refining technology to produce products that...
