| description | The invention relates to a catalyst for hydrocarbon conversion reaction, which is characterized in that the catalyst is formed by combining an inner substance and an outer substance with different properties, the inner first layer substance has lower porosity, the outer second layer substance has a first type of pores and a second type of pores, and the maximum value of the pore size distribution of the first type of pores is 4-50nm, and the maximum value of the pore size distribution of the second type of pores is 100-1000nm. The catalyst has relatively low permeability of a first layer of noble metal carrier, is beneficial to recovery of noble metal, has outstanding selectivity and activity in a long-chain hydrocarbon conversion reaction, especially in a process of preparing monoolefine by dehydrogenation of C10-C15 long straight-chain alkane and a selective hydrogenation reaction of C10-C15 long-chain diolefin, and also has relatively good stability; selectivity can be obviously improved, side reactions ar |
