Abstract

The invention provides a catalyst for processing shale oil, a preparation method thereof, a shale oil processing system and a processing method thereof. The catalyst is in the form of a porous catalyst composed of SiO2, Al2O3 and an adsorption auxiliary agent. The catalyst is prepared by the following materials in weight percentage: 65-90 wt% of pseudo-boehmite, 0-30 wt% of clay, 2-20 wt% of binder and 1-15 wt% of adsorption auxiliary agent. According to the technical scheme of the invention, the shale oil is subjected to adsorbing and cracking by adopting the catalyst of high adsorption performance. On the premise that nitride, colloid, and heavy metal in the shale oil are removed, the diesel yield and the total liquid yield are improved. Meanwhile, the yield of dry gas and coke is reduced. Since the contents of colloid, nitride and heavy metal are reduced, shale oil processed products are higher in stability. The coking condition of shale oil processing equipment is improved. Based on the method, products of high economic value can be produced by reasonably utilizing the shale oil.

Description

technical field [0001] The invention belongs to the field of petrochemical industry, and relates to a catalyst for shale oil processing and a preparation method thereof, a shale oil processing system and a processing method thereof. Background technique [0002] my country's oil shale resources are very rich, with reserves of about 16 billion tons, ranking fourth in the world. The shale oil industry is an important part of the energy industry and a supplementary energy source to natural oil. Compared with conventional crude oil, shale oil has a high content of polycyclic aromatic hydrocarbons, nitrogen compounds, especially basic nitrogen compounds, which are 5-10 times higher than conventional crude oil, colloid content 2-8 times higher than conventional crude oil, diesel fraction ( 200~350°C), the mass yield is twice that of crude oil, and in addition to many non-hydrocarbon compounds such as sulfur, nitrogen and oxygen, it also contains a large amount of impurities such ...
