Abstract

The invention discloses a catalytically cracked oil slurry furfural extracted oil hydrogenation catalyst, and a preparation method and applications thereof. The catalytically cracked oil slurry furfural extracted oil hydrogenation catalyst comprises a carrier and an active component; the active component is loaded by the carrier; the carrier is a composite carrier comprising TS-1 molecular sieve,gamma-Al2O3, ZrO2, and graphene; the active component is loaded onto the carrier through one time or multiple time dipping; an adopted dipping solution is a heteropoly acid solution; 100wt% of the catalytically cracked oil slurry furfural extracted oil hydrogenation catalyst comprises 1 to 30wt% of TS-1 molecular sieve, 20 to 50wt% of gamma-Al2O3, 1 to 10wt% of ZrO2, 1 to 5wt% of graphene, and 30to 40wt% of the active component. The catalytically cracked oil slurry furfural extracted oil hydrogenation catalyst is high in hydrodesulfurization and denitrification activity, and is suitable to betaken as a catalytically cracked oil slurry furfural extracted oil hydrogenation catalyst.

Description

technical field [0001] The invention relates to a catalytic cracking oil slurry furfural refined oil hydrogenation catalyst, which is suitable for the hydrogenation process of catalytic cracking oil slurry furfural refined oil in the field of petroleum refining. Background technique [0002] Using furfural as a solvent, the alkanes and aromatics in the catalytic cracking oil slurry are separated to obtain aromatic-rich extracted oil and alkane-rich raffinate oil. High-purity heavy aromatics can produce high value-added aromatics products, and the alkane-rich part is a high-quality catalytic cracking raw material, which can be re-smelted to significantly improve economic benefits. [0003] However, the sulfur and nitrogen content in the extracted oil and raffinate oil are relatively high, and subsequent processing has certain difficulties. After hydrofining the raffinate oil as a high-quality catalytic cracking raw material, it can not only produce low-sulfur gasoline and di...
