Problems solved by technology

However, metal oxides and organic polymers have disadvantages such as low specific surface area, which is not conducive to the dispersion of ionic liquids, resulting in low loading efficiency and low catalytic activity.
Although the specific surface area of ​​mesoporous silicon material is low, its pores are easily blocked, making it difficult to recycle.

Abstract

The invention discloses a preparation method of a graphene-like boron nitride (G-BN) loading ionic liquid (IL) catalyst. The catalyst takes graphene-like boron nitride as a carrier, and an ionic liquid is carried in a solid state to the catalyst which is synthesized on graphene-like boron nitride, wherein the graphene-like boron nitride is a single-layer or less-layer boron nitride, the ionic liquid is a metal-matrix polyacid ionic liquid, and the molecular formula thereof is Q2 [M6O19], where M is a central atom which is tungsten and molybdenum, Q is a cation which is a quaternary phosphonate cation(I) or a quaternary ammonium cation (II), and R1, R2, R3 and R4 are linear chain alkyls. The catalyst disclosed by the invention has the advantages of having high sulfur removal efficiency, short reaction time, simple reaction system, mild reaction conditions, easy separation and convenient recycling and requiring no pressurization equipment.

Description

technical field [0001] The invention relates to a catalyst, in particular to a preparation method of a supported ionic liquid catalyst with graphene-like boron nitride as a carrier and its use in the oxidative desulfurization reaction of gasoline and diesel (fuel oil). Background technique [0002] The design and synthesis of catalysts have always been the core of modern chemical research and industrial catalytic production. Catalysts can be classified into homogeneous catalysts and heterogeneous catalysts according to the relationship between catalysts and reaction systems. Homogeneous catalysts have the advantages of high reactivity and mild reaction conditions, but there are difficulties in recovery and recycling of homogeneous catalysts. Although the heterogeneous catalyst is a kind of catalyst that is easy to recover and separate, its catalytic activity is not high, and the loss of catalytic active centers is the disadvantage of heterogeneous catalysis. Therefore, fin...
