| titleOfInvention | Catalyst for preparing methyl acetate by methanol carbonylation and application thereof |
| abstract | The invention provides a catalyst for preparing methyl acetate by methanol carbonylation, belonging to the technical field of catalysts. The catalyst for preparing methyl acetate by methanol carbonylation provided by the invention comprises a metal modified molecular sieve, an insulating material and a multi-metal oxide; the metal element in the metal modified molecular sieve comprises at least one of iron, cobalt, nickel, copper, silver and zinc; the metal elements in the multi-metal oxide include at least two of magnesium, aluminum, manganese, copper, zinc and cerium. The polymetallic oxide in the catalyst for preparing methyl acetate by methanol carbonylation provided by the invention converts water generated by methanol dehydration into H 2 And CO 2 The adverse effect of water on the carbonylation reaction is avoided, the carbonylation reaction is promoted to be carried out, the catalyst has the selectivity of more than 90 percent when being used for preparing the methyl acetate by the conversion of the methanol, and the service life of the catalyst for preparing the methyl acetate by the carbonylation of the methanol can be prolonged by the carbon burning regeneration circulation; does not contain halide catalyst and has no corrosion to equipment. |
