An catalyst for gasoline desulfuration deodorization, the formula of the catalyst is Q l B m H n [A x M y O z ] (l+m+n)- , wherein: Q denotes a cation of a quaternary ammonium salt,its constitute is R 1 R 2 R 3 R 4 N + , and R 1 , R 2 , R 3 and R 4 respectively denote a saturated alkyl group of C 1 -C 20 , a proviso is at least one of R 1 , R 2 , R 3 and R 4 denotes a saturated alkyl group of C 4 -C 20 ; 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. |
