| titleOfInvention | A kind of method for preparing cyclohexane by hydrogenation of benzene |
| abstract | The invention belongs to the field of chemical industry, and specifically discloses a method for preparing cyclohexane by hydrogenation of benzene. The method is carried out in two-stage reactors connected in series, wherein the first-stage reactor is filled with a metal-polymer composite catalyst, and the first-stage reactor is filled with a metal-polymer composite catalyst. The secondary reactor is filled with a composite hydrogenation catalyst; the metal-polymer composite catalyst comprises a polymer matrix cross-linked by a polybasic acid and a metal active component platinum, and the polymer matrix is a polymer containing nitrogen-containing heterocyclic side groups; The composite hydrogenation catalyst includes continuous phase carbon and dispersed phase Raney alloy particles, wherein the dispersed phase Raney alloy particles are uniformly or inhomogeneously dispersed in the continuous phase carbon. In the present invention, the metal-polymer composite catalyst and the composite hydrogenation catalyst are used for hydrogenation successively, so that benzene is completely converted into cyclohexane. |
