PROCESS FOR HYDROGENATING BENZENE TO CYCLOHEXANE

摘要

the invention relates to a process for the hydrogenation of benzene to cyclohexane in the presence of the catalyst of nickel promotat type medium at temperatures of 165...260 degree c and at pressures ranging between 8 and 15 at two steps, in which at least the first reactor heat multitubular fickle and was like,in order diminuarii content of hydrogen in a hydrogen purge using molar ratio of 3.2 to 1,0 to aromatic volumara speed over 1,2 i / m3 benzene liquid cubic catalyst per hour and at a flow rate of the flow of reactants in the fixed bed of catalyst over 0,2m / s secure by construction dilutia reactors and hydrogen with inert.
