Cyclohexane

Abstract

Benzene and hydrogen-rich gas are fed to a liquid-phase reactor in which raney nickel catalyst is maintained in uniform dispersion at a temperature below 2500C and a pressure above 3 bar. Overheads are sent to a finishing reactor where the remaining benzene is converted Use of the second reactor allows the main liquid-phase reactor to be kept to a reasonable size. Effl uent pressure be used. from the second reactor is cooled and liquid separated in a high drum. Benzene from hydroxyalkyl at i on or RTX extract i on feeds may Hydrogen feeds must have low sulphur and carbon oxide levels.
