Patent number: 8501657Abstract: A catalyst for the desulfurization and deodorization of gasoline, which is expressed by the formula: QlBmHn[AxMyOz](1+m+n)?, where: Q denotes a quaternary ammonium cation consisting of R1R2R3R4N+, in which R1, R2, R3, and R4 each denotes independently a C1 to C20 saturated alkyl group, respectively, provided that at least one of R1, R2, R3, and R4 denotes a C4 to C20 saturated alkyl group; B denotes a metal cation of Na+ or/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.Type: GrantFiled: November 20, 2008Date of Patent: August 6, 2013Assignee: Dalian Institute of Chemical Physics, Chinese Academy of ScienceInventors: Can Li, Zongxuan Jiang, Yongna Zhang, Hongying Lv, Boyu Zhang
