摘要: A method for preparing a polyolefin resin powder has the steps of a) heat dissolving a polyolefin resin in an organic solvent having a solubility parameter less than or equal to the solubility parameter of the polyolefin resin to obtain a polyolefin resin solution; b) cooling the polyolefin resin solution to precipitate a solid, thereby obtaining a solid-liquid mixture; c) optionally adding an adjuvant to the solid-liquid mixture and mixing; and d) conducting solid-liquid separation and drying to obtain a polyolefin resin powder suitable for selective laser sintering. The difference between the solubility parameters of the organic solvent and of the polyolefin resin is within 0-20% of the solubility parameter of the polyolefin resin.
The polyolefin resin powder obtained according to this method has good antioxidant property, good powder flowability, moderate size, smooth surface, suitable bulk density, and suitable dispersibility and particle size distribution.-

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%.
