Abstract
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≦l≦10, 0≦m≦3, 0≦n≦3, l+m+n≦14, x=1 or 2, 9≦y≦18, 34≦z≦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° 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.
