Method of preparing methyl cyclo pentane by continuous hydrogenation of methyl cyclo pentadiene

The continuous methyl cyclopentadiene hydrogenating process to prepare methyl cyclopentane is one continuous catalytic hydrogenation reaction of the mixture of methyl cyclopentadiene, solvent and hydrogen in a fixed bed catalyst bed. The catalyst includes gamma-Al2O3 as carrier and Pa as active component. The solvent is any one of methyl cyclopentane, cyclopentane, n-hexane, benzene, toluene, cyclohexane, methanol, tertiary amyl alcohol and tertiary butyl alcohol. The reacted liquid is discharged partially and externally circulated partially with the weight ratio being 1 to 6-10, and the externally circulated liquid after being cooled is mixed with methyl cyclopentadiene material and solvent before being mixed with hydrogen in venturi ejector, atomized into gas-liquid mixture and reacted in the catalyst bed. The catalyst load is 2-3/hr accounted in liquid phase material, and the reacted heat is transferred via external circulation. The present invention has high yield.
