Abstract

The invention discloses a Fischer-Tropsch synthetic oil processing technology. The technology comprises the following steps: (1) Fischer-Tropsch synthetic oil enters a hydrogenation pretreatment reactor for a reaction; (2) the material flow in the step (1) enters a hydrocracking reactor, a hydrocracking reaction zone and a hydrocracking product fractionation zone are arranged in the hydrocracking reactor, and the hydrocracking reaction zone is at least provided with two hydrocracking catalyst bed layers, the material flow after the hydrofining reaction in the step (1) enters a hydrocracking reactor from the bed layer of the hydrocracking catalyst for hydrocracking reaction; and (3) obtaining hydrocracked unconverted oil from the bottom of the hydrocracking reactor in the step (2), obtaining diesel oil from a side line of a hydrocracking product fractionation area, and fractionating a material flow at the top of the hydrocracking reactor to obtain hydrogen and naphtha. According to the method, the condensation point of the diesel oil produced by hydrocracking the full-fraction boiling-Tropsch synthetic oil is improved, and meanwhile, the diesel oil selectivity is improved.

Description

technical field [0001] The invention relates to a Fischer-Tropsch synthetic oil processing technology, in particular to a Fischer-Tropsch synthetic oil hydrocracking process for producing diesel oil. Background technique [0002] my country is short of petroleum resources, and its dependence on foreign crude oil exceeds 70%. Relatively speaking, my country's coal resources are relatively rich. In addition to being used for power generation and heating, coal chemical industry has developed rapidly in my country in recent years. [0003] Among them, the Fischer-Tropsch synthesis process has been widely developed in my country because it can convert coal into Fischer-Tropsch synthetic oil. The hydrocarbon structure of Fischer-Tropsch synthetic oil is mainly composed of paraffins, which is a very good hydrocarbon resource. High-cetane, low-sulfur diesel components and / or premium lubricating oils can be produced by hydrocracking or hydroisomerization. [0004] Chinese patent CN...
