| Abstract: | Utilization of CO2 for the alkylation of aromatic hydrocarbons is one of the green and sustainable routes for the production of valuable alkylated aromatics like xylenes. The present invention deals with the development of single-step catalytic process for the production of alkylated aromatics using CO2 as a carbon source & alkylation reagent and methylcyclohexane as a hydrogen atom donor as well as source of toluene. In presence of the metal functionalized zeolite catalyst, methylcyclohexane undergoes dehydrogenation to produce toluene and hydrogen; hydrogen reacts with CO2 to form active alkylating species which triggers the alkylation of toluene. Here, we disclosed a novel process for the production of xylene-rich alkylated aromatics from methylcyclohexane and CO2 using single multi-functional catalyst possessing dehydrogenation, hydrogenation and acid functionalities. |
