CATALYST FOR GASOLINE DESULFURATION DEODORIZATION, ITS PREPARATION METHOD AND UTILIZATION

摘要

An catalyst for gasoline desulfuration deodorization, the formula of the catalyst is QlBmHn[AxMyOz](l+m+n)-, wherein: Q denotes a cation of a quaternary ammonium salt,its constitute is R1R2R3R4N+, and R1, R2, R3 and R4 respectively denote a saturated alkyl group of C1-C20, a proviso is at least one of R1,R2, R3 and R4 denotes a saturated alkyl group of C4-C20; B denotes a cation of metal Na+ or / and K+; H denotes a hydrogen atom; A denotes a central atom B, P, As, Si or Al; M denotes a ligand atom 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 are integers. A method for gasoline desulfuration deodorization using the catalyst, comprises : mixing the catalyst and hydrogen peroxide, and then adding gasoline, and reacting for 10-180 minutes under the conditions of 25?-90?and 0.1-1MPa, then obtaining an odorless gasoline by standing or centrifugal separation, and recycling the catalyst.
