Accordingly, the present invention provides a catalyst composition suitable for converting light naphtha comprising one or more of C5 to C8 carbon atoms to aromatic compounds ranging from C6 to C10 carbon atoms, said catalyst composition comprising: (a) a medium pore size zeolite; (b) 0.1 to 5.0 wt % of zinc; and (c) 0.1 to 5 wt % of gallium. Also, the present invention provides a process for converting light naphtha comprising one or more of C5 to C8 carbon atoms to aromatic compounds ranging from C6 to C10 carbon atoms, said process comprising the step of contacting a feedstock comprising the light naphtha with a catalyst composition comprising (a) a medium pore size zeolite; (b) 0.1 to 5.0 wt % of zinc; and (c) 0.1 to 5 wt % of gallium in presence of carrier gas at temperatures ranging from 400&#xb0; to 600&#xb0; C.

Catalyst composition for converting light naphtha to aromatic compounds and a process thereof

The present disclosure relates to a process for the preparation of isomers of xylene. The process includes method step of contacting an activated alkylation catalyst composite with toluene and methanol in the presence of an inert gas, at a temperature of 300 to 500&#xb0; C. to obtain isomers of xylene. The alkylation catalyst composite used in accordance with the present disclosure comprises a molecular sieve loaded with at least one metal ion. The metal loaded on the molecular sieve is at least one alkali earth metal selected from the group consisting of barium, strontium, magnesium and calcium.
