摘要 |
Hydrogenation of benzene comprises two stages: (a) the charge-contg. benzene and a H2-rich gas is progressively introduced to a reaction zone contg. a liq. phase rich in cyclohexane, and a Ni-based catalyst in suspension in this phase. The zone is maintained at 100-250<0> C and 0.5-10 MPa, and a gaseous phase is recovered contg. cyclohexane, H2 and benzene; (b) the gaseous effluent from (a) is directed to a reactor contg at least one fixed bed of a solid Ni-based hydrogenation catalyst and operating at 100-300<0> C, 0.5-10 MPa and vol. velocity 1-10 h<-1>. After expansion and cooling pure cyclohexane is obtd. The catalyst used in stage (a) is a prod. resulting from the redn. of at least one nickel carboxylate, R<4>.COO Ni. R<4> = 1-24(pref. 6-12)C hydrocarbyl and at least one sodium carboxylate, R<5>.COO Na; R<5> = 1-24 hydrocarbyl Ämolar ratio of Ni:Na = 2:1 to 1000:1Ü by at least one trialkyl-aluminium, AlR<1>R<2>R<3>; R<1>,R<2>,R<3> (independently) = 1-12C alkyl, in soln. in an hydrocarbon or hydrocarbon mixt. Also claimed is the Ni-based catalyst prepared as above. |
