ABSTRACT:
Cycloalkylaromatics are produced from aromatic hydrocarbons in the presence of hydrogen and an aqueous HF-treated ruthenium halide-active clay catalyst which has been promoted with at least one compound of iron, cobalt, and nickel. Preferably the catalyst has not been heated under calcination conditions prior to use. In a specific embodiment, benzene is converted to cyclohexylbenzene with good selectivity over an active clay impregnated with ruthenium chloride and hydrogen fluoride and at least one compound of iron, cobalt, and nickel.
