The invention belongs to the technical field of chemistry and chemical industry, in particular to a composite catalyst containing spinel structure oxides and its application in one-step synthesis of olefins from synthesis gas. high problem. The catalyst is a composite catalyst containing spinel structure oxide, which is characterized by comprising spinel structure oxide and phosphorus-aluminum molecular sieve, and can realize the one-step production of olefin with high selectivity of synthesis gas. The catalyst better solves the above problems, can efficiently, continuously and stably prepare C 2 -C 4 olefin products, and can be used in the industrial production of synthetic gas to light olefins. |
