Abstract：
 The present invention belongs to the field of catalyst preparation in chemical technology. The samarium nitrate or samarium chloride is prepared into the samarium oxide catalyst through the steps of dissolving in deionized water, dropping into ammonia water solution as precipitant, ageing, washing, drying and roasting to obtain the samarium oxide catalyst of Sm2O3-B, Sm2O3-C, Sm2O3-D, Sm2O3-B*, Sm2O3-D* or Sm2O3-E*. The catalyst is used in the isomerized synthesis with mixed CO and H2 material under heating and pressurized condition in a fixed bed reactor to obtain isomerized C4 hydrocarbon product. It has CO converting rate of 3-8 %, isomerized C4 hydrocarbon mixture gas selectivity of 42-69 %, the ratio between the C4 hydrocarbon to isomerized C4 hydrocarbon mixture gas of 35-77 %, and the ratio of isobutylene and isobutane to isomerized C4 hydrocarbon of 44-100 %.
