Embodiment 1

[0102] This embodiment is used to illustrate the method for the mixed processing coal tar and Fischer-Tropsch synthetic oil of the present invention, produces solvent oil, and the method of this embodiment is based on figure 1 The flowchart shown proceeds, specifically, as follows:

[0103] In this example, mixed oil 1 is used as the raw material oil, which enters the hydrogenation protection reactor and the hydrofinishing reactor successively, and is sequentially combined with the hydrogenation protection catalysts RGC-20, RGC-30E, RGC-30A, RGC-30B, RGC-1 Contact and react with the hydrofining catalyst RTC-2, the hydrofinishing reaction effluent enters the separation system for separation, and the separated liquid effluent enters the fractionation tower to cut out naphtha fraction, solvent oil fraction and tail oil. The tail oil fraction enters the hydrocracking reactor as the raw material of the hydrocracking reaction and contacts with the hydrocracking catalyst RCF-1 for fu...

Embodiment 2

[0119]This embodiment is used to illustrate the method for the mixed processing coal tar and Fischer-Tropsch synthetic oil of the present invention, produces jet fuel, and the method of this embodiment is based on figure 1 The flowchart shown proceeds, specifically, as follows:

[0120] In this example, the mixed oil 2 is used as the raw material oil, which enters the hydrogenation protection reactor and the hydrofinishing reactor in turn, and is sequentially combined with the hydrogenation protection catalysts RGC-20, RGC-30E, RGC-30A, RGC-30B, RGC-1 Contact and react with the hydrofining catalyst RTC-2, the hydrofinishing reaction effluent enters the separation system for separation, and the separated liquid effluent enters the fractionation tower to cut naphtha fraction, jet fuel and tail oil. The tail oil fraction enters the hydrocracking reactor as the raw material for hydrocracking and contacts with the hydrocracking catalyst RCF-1 for further hydroconversion. The hydroc...

Embodiment 3

[0131] This embodiment is used to illustrate the method for the mixed processing coal tar and Fischer-Tropsch synthetic oil of the present invention, produces diesel product, and the method of this embodiment is based on figure 1 The flowchart shown proceeds, specifically, as follows:

[0132] In this example, the mixed oil 3 is used as the raw material oil, which enters the hydrogenation protection reactor and the hydrofinishing reactor in turn, and is sequentially combined with the hydrogenation protection catalysts RGC-20, RGC-30E, RGC-30A, RGC-30B, RGC-1 Contact and react with the hydrofining catalyst RTC-2, the hydrofinishing reaction effluent enters the separation system for separation, and the separated liquid effluent enters the fractionation tower to cut naphtha fraction, diesel fraction and tail oil. The tail oil fraction enters the hydrocracking reactor as the raw material for hydrocracking and contacts with the hydrocracking catalyst RHC-131 for further hydroconver...

Abstract

The invention relates to the field of petrochemical industry, and discloses a method for mixing and processing coal tar and Fischer-Tropsch synthetic oil. Reaction in the refining reaction zone to obtain the hydrofining reaction effluent, wherein the weight ratio of the Fischer-Tropsch synthetic oil and coal tar is 1:0.01-1.50; (2) separating the hydrofining reaction effluent and any Selected mixture with the effluent from the hydrocracking reaction zone to obtain a liquid effluent; (3) fractionating the liquid effluent to obtain the target product and naphtha and tail oil, optionally the tail Oil is introduced into the hydrocracking reaction zone for reaction. The method can overcome the defects of high temperature sensitivity and low product yield caused by secondary cracking in the process of processing Fischer-Tropsch synthetic oil in the prior art.

Description

technical field [0001] The invention relates to the field of petrochemical industry, in particular to a method for mixing and processing coal tar and Fischer-Tropsch synthetic oil. Background technique [0002] At present, the main source of fuel used by various means of transportation in the world is petroleum, and various derivatives of petroleum provide a strong driving force for economic and social development. However, petroleum, as a non-renewable energy source, is facing the crisis of depletion day by day, and the quality of crude oil is getting worse and worse, and the non-ideal components such as polycyclic aromatic hydrocarbons, sulfur and nitrogen in the composition of its derivatives are increasing day by day. Before becoming a fuel commodity, it needs to go through an increasingly complex processing process to remove components that affect the environment, resulting in a substantial increase in production and processing costs. Therefore, there is a need to find...
