A catalyst for the desulfurization and deodorization of gasoline, which is expressed by the formula: QBH[AMO], where: Q denotes a quaternary ammonium cation consisting of RRRRN, in which R, R, R, and Reach denotes independently a Cto Csaturated alkyl group, respectively, provided that at least one of R, R, R, and Rdenotes a Cto Csaturated alkyl group; B denotes a metal cation of Naor/and K; H denotes a hydrogen atom; A denotes a central atom of B, P, As, Si or Al; M denotes a coordinated atom of W or Mo; O denotes an oxygen atom; 1&#x2266;l&#x2266;10, 0&#x2266;m&#x2266;3, 0&#x2266;n&#x2266;3, l+m+n&#x2266;14, x=1 or 2, 9&#x2266;y&#x2266;18, 34&#x2266;z&#x2266;62, and l, m, n, y and z all are integers. A method of the desulfurization and deodorization of gasoline by using the catalyst comprises the steps of: mixing the catalyst and an aqueous solution of hydrogen peroxide, and then adding the gasoline to react them with stirring under conditions of 25 to 90&#xb0; C. and 0.1 to 1 MPa for 10 to 180 min. An odorless gasoline can be obtained through settlement or centrifugation, and the catalyst is recovered.

Catalyst for desulfurization and deodorization of gasoline and method for preparation of the same and use thereof

A catalyst for ultra-deep desulfurization of diesel via oxidative distillation is an amphiphilic oxidative catalyst, which is expressed as Q[XMO], wherein 1&#x2266;m&#x2266;12; 9&#x2266;n&#x2266;18; 34&#x2266;q&#x2266;62; Q is a quaternary ammonium cation; X is P, Si, As or B; and M is Mo) or W. A desulfurization method comprises a) mixing well a diesel, the amphiphilic catalyst, and hydrogen peroxide, reacting for 10-300 minutes at ambient temperature and normal pressure, transforming the sulfur-containing compounds in the diesel into sulfone to obtain an oxidized diesel; b) distilling the oxidized diesel obtained in step a) under reduced pressure to obtain the ultra-low sulfur diesel having a sulfur content of less than 10 ppm; and c) separating and recovering the catalyst and sulfone.
