Abstract

The invention relates to a hydrogenation processing method of Fischer-Tropsch synthetic oil full cut and the method is that the Fischer-Tropsch synthetic oil full cut is subjected to two-step hydrogenation processing and then enters a first separation system; the tail oil obtained by separation undergoes hydrogen cracking and the hydrogen cracking products acquired enter a second separation system. The invention can acquire high-quality clean diesel oil with cetane value higher than 75 and excessively low-freezing clean oil with solidifying point lower than 50 DEG C below zero, meanwhile, naphtha acquired is high-quality raw material used for producing ethylene by steam cracking.

Description

technical field [0001] The invention relates to a hydrogenation processing method of full fraction Fischer-Tropsch synthetic oil, in particular to a hydrogenation processing method for effectively processing full fraction Fischer-Tropsch synthetic oil into high-quality motor fuel and high-quality chemical raw material. Background technique [0002] Fossil fuels mainly include coal and petroleum. From a global perspective, the reserves of coal far exceed the reserves of petroleum. Therefore, how to replace petroleum with coal is an important topic in the energy field. The important process for coal to replace petroleum is the liquefaction process of coal and the further processing process of coal liquefaction products. [0003] According to different routes of chemical processing, coal liquefaction can be divided into two categories: direct liquefaction and indirect liquefaction. Coal direct liquefaction is the direct conversion of coal into liquid products. The main proce...
