Provided are a supported catalyst, a preparation method therefor and use thereof, and a method for the preparation of isobutylene from halomethane. The catalyst is characterized in that it comprises a carrier and a metallic active component supported on the carrier, wherein the metallic active component comprises zinc oxide and zinc halide. On the basis of the total amount of the catalyst, by weight content, the content of zinc oxide is 0.5%-20%, the content of zinc halide is 10%-50%, and the content of the support is 40%-88%. Compared with the prior art, the catalyst of the present invention can convert halomethane into isobutylene with a high selectivity. With the reaction for preparing of isobutylene by converting bromomethane according to the method of the present invention, the conversion of bromomethane is not less than 90% and the selectivity of isobutylene is not less than 80%.

Supported catalyst, preparation method therefor and use thereof, and method for preparation of isobutylene from halomethane

The present invention discloses a catalyst for paraffin isomerization, as well as a preparation method and use thereof. The catalyst comprises a TON molecular sieve modified by rare earth, an inorganic refractory oxide modified by zirconium oxide and a noble metal of group VIII. The weight ratio of the TON molecular sieve modified by rare earth to the inorganic refractory oxides modified by zirconium oxide is 10:90 to 90:10, and the content of the metal of group VIII is 0.1 to 10 wt % based on the metal. When used in the process of isomerization dewaxing of various raw materials containing paraffins, the catalyst can not only decrease the solidifying points of raw oil containing paraffins, but also increase the yield of liquid products. Particularly, when used in the process of isomerization dewaxing of lubricating oil distillates, the catalyst is advantageous in producing base oil for lubricating oil with a high a higher yield, a lower pour point (solidifying point) and a higher viscosity index.
