Benzene to Cyclohexane

Benzene is an undesirable carcinogenic impurity in gasoline. The RD process developed by CR&L, shown in Fig. 1.5, uses a supported nickel catalyst at high temperature (260-280 °C) and high pressure (6 atm) and offers several advantages apart from highly selective separation. RD facilitates efficient contact of hydrogen with benzene, substantial removal of heat of reaction, good temperature control, and in-situ catalyst washing to increase its life [63, 64],
