Other AbstractProvided are a catalyst applied to producing methane and co-producing low carbon olefin by converting syngas and processes for preparing the catalyst and producing the methane and co-producing the low carbon olefin by converting the syngas. The catalyst is composed of ACuFe2O3, the active component is transition metal oxide ferric oxide, and the total content of ferric oxide accounts for 78.0-98.5wt% of the total weight of the catalyst. A promoter A is manganese (Mn), kalium (K), zinc (Zn) and/or zirconium (Zr), and the content of the promoter A accounts for 1.0-15.0wt% of the total weight of the catalyst. The content of an assistant cuprum (Cu) accounts for 0.5-7.0wt% of the total weight of the catalyst. The preparation of the catalyst adopts a coprecipitation method, ammonia water solution with a certain concentration serves as a precipitator, and metal salt serves as a raw material. The catalyst is obtained by aging, drying and roasting the precipitate at the temperature of 400 DEG C to 800 DEG C. The syngas serving as a raw material is wide in source and can be obtained from coal or biomass. The catalyst is low in cost, simple in preparation process, high in reaction activity and suitable for continuous large-scale production. | 一种经合成气制甲烷并联产低碳烯烃反应所用的催化剂、其制备及合成甲烷联产烯烃的工艺。催化剂组成为ACuFe2O3,活性组分为过渡金属氧化物氧化铁,氧化铁的总含量为催化剂总重量的78.0-98.5wt%;A为助催化剂Mn、K、Zn、Zr,含量为催化剂总重量的1.0-15.0wt%;助剂Cu含量为催化剂总重量的0.5-7.0wt%。催化剂的制备采用共沉淀法,一定浓度的氨水溶液作为沉淀剂,金属盐作为原料。所得沉淀经老化、干燥、400-800℃焙烧1~20小时而得到。本发明的原料为合成气,其来源广泛,既可从煤也可从生物质得到,催化剂成本低廉,制备过程简单,反应活性很高,适合连续大规模生产。
