An aspect of the present disclosure relates to a process for preparing a composite hydroalkylation catalyst including: (a) effecting impregnation of a hydrogenation metal on an inorganic oxide to form a metal impregnated inorganic oxide; (b) effecting calcination of the metal impregnated inorganic oxide to obtain a calcined metal impregnated inorganic oxide; (c) preparing a composite mixture comprising a molecular sieve, the calcined metal impregnated inorganic oxide and a binder; (d) preparing an extruded catalyst; and (e) effecting calcination of the extruded catalyst to obtain the composite hydroalkylation catalyst. The composite hydroalkylation catalyst prepared using this process affords dramatic improvement in conversion of mononuclear aromatic hydrocarbon and the yield of the hydroalkyled mononuclear aromatic hydrocarbon (e.g. CHB).

Hydroalkylation of mononuclear aromatic hydrocarbons to mono cycloalkyl aromatic hydrocarbons

In accordance with the present subject matter there is provided a process for catalytic decomposition of lower hydrocarbons to produce carbon oxides free hydrogen and bamboo shaped carbon nanotubes over a catalyst composition. The process for catalytic decomposition of lower hydrocarbons comprises contacting lower hydrocarbon over a catalyst composition, where the catalyst composition comprising, a catalyst, at least one modifying agent and a support material.
