摘要：
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%.
摘要（中）：
提供负载型催化剂，其制备方法及其用途，以及由卤代甲烷制备异丁烯的方法。 该催化剂的特征在于它包含载体和负载在载体上的金属活性组分，其中金属活性组分包含氧化锌和卤化锌。 以催化剂总量为基准，按重量计，氧化锌含量为0.5％〜20％，卤化锌含量为10％〜50％，载体含量为40％〜88％ ％。 与现有技术相比，本发明的催化剂可以高选择性地将卤代甲烷转化为异丁烯。 根据本发明的方法通过转化溴甲烷制备异丁烯的反应，溴甲烷的转化率不小于90％，异丁烯的选择性不小于80％。
