Abstract

The invention relates to novel carboxylic acid functional rhenium iron liquid and a preparation method and application thereof. The preparation method of the ion liquid comprises the following steps: carrying out reaction between alkyl imidazole and ethyl chloroacetate to generate an ion liquid intermediate, acidifying the ion liquid intermediate by concentrated hydrochloric acid to decompose ester into carboxylic acid, and reacting the acidified ion liquid intermediate with silver perrhenate to obtain a product. The rhenium iron liquid is used for FCC gasoline oxidative desulfurization, the detected sulfur content of the oil phase is lower than 100ppm, and meanwhile, other performance indexes of the oil product do not significantly change, and the Euro V standard is reached basically.

Description

technical field

[0001] The invention belongs to the field of chemical catalysis and desulfurization of gasoline and diesel oil, and in particular relates to the synthesis of a novel ionic liquid catalyst and a method for catalytic oxidation desulfurization of FCC gasoline by using the ionic liquid. Background technique

[0002] With the increasingly stringent environmental protection regulations in the world, the oil refining industry is facing huge challenges in terms of production and environmental protection in response to new fuel standards. Petroleum companies at home and abroad are also actively researching and developing clean fuel oil production technologies. Vehicle fuel oil desulfurization technologies mainly include hydrodesulfurization, catalytic cracking desulfurization, adsorption desulfurization, extraction desulfurization, biological desulfurization, etc. Hydrodesulfurization (HDS) is the most mature desulfurization process at present, but because dibenzothio...
