摘要： The invention discloses a method for the pervaporation and vapor-permeation separation of a gas-liquid mixture or a liquid mixture by a SAPO-34 molecular sieve membrane prepared in a dry gel process, comprising: 1) synthesis of SAPO-34 molecular sieve seeds; 2) coating the SAPO-34 seeds on a porous support; 3) preparation of a mother liquor for dry gel synthesis of SAPO-34 molecular sieve membrane; 4) supporting the mother liquor for dry gel synthesis on the porous support coated with SAPO molecular sieve seeds and drying; 5) placing the porous support prepared in step 4) into a reaction vessel, adding a solvent, performing crystallization of the dry gel; 6) calcining; 7) using the SAPO-34 molecular sieve membrane obtained from step 6) to perform separation of a gas-liquid mixture or a liquid mixture by a process of pervaporation separation or vapor-permeation separation. The invention has the advantages of very high methanol selectivity and permeation flux, lowering synthesis cost of molecular sieve membrane and lowering environment pollution.

摘要： A cobalt carbide-based catalyst for direct production of olefin from synthesis gas, a preparation method therefor and application thereof are disclosed. The method for preparing the catalyst comprises the following steps: 1) mixing a cobalt source with water, or mixing a cobalt source, an electron promoter and water to obtain a first solution; and mixing a precipitant with water to obtain a second solution; 2) adding the first solution and the second solution to water, or water and a structure promoter for precipitation, crystallizing, separating, drying and calcination; and 3) reducing a solid obtained in Step 2) in a reducing atmosphere, and then carbonizing in a carbonizing atmosphere. The prepared catalyst has high activity and high selectivity to olefins for direct production of olefins via syngas conversion.
