摘要： The present invention provides a method for preparing acetic acid by carbonylation of methanol, which comprises: passing a raw material containing methanol, carbon monoxide and water through a reaction region loaded with a catalyst containing an acidic molecular sieve with an adsorbed organic amine, and carrying out a reaction under the following conditions to prepare acetic acid. The method in the present invention offers high acetic acid selectivity and good catalyst stability. The catalyst in the present invention does not contain noble metals such as rhodium or iridium, and does not need additional agent containing iodine, and thus does not generate a strong corrosive hydroiodic acid and the like.

摘要： An alkylation catalyst having a zeolite catalyst component and a binder component providing mechanical support for the zeolite catalyst component is disclosed. The binder component is an ion-modified binder that can include metal ions selected from the group consisting of Co, Mn, Ti, Zr, V, Nb, K, Cs, Ga, B, P, Rb, Ag, Na, Cu, Mg, Fe, Mo, Ce, and combinations thereof. The metal ions reduce the number of acid sites on the zeolite catalyst component. The metal ions can range from 0.1 to 50 wt % based on the total weight of the ion-modified binder. Optionally, the ion-modified binder is present in amounts ranging from 1 to 80 wt % based on the total weight of the catalyst.
