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. Aspects of the present invention deal with the development of single-step catalytic process for the production of alkylated aromatics using CO2 as a carbon source and 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. Additionally, a novel process is disclosed for the production of xylene-rich alkylated aromatics from methylcyclohexane and CO2 using single multi-functional catalyst possessing dehydrogenation, hydrogenation and acid functionalities.

More particularly, the disclosure provides for the co-location of a biomass reactor unit and an aromatization reactor unit to produce benzene from a renewable source such as plant mass. Hexane produced from cellulose in the biomass reactor unit can be converted to benzene in the aromatization reactor unit and hydrogen produced in the aromatization reactor unit can be used in the biomass reactor unit. Also described is the use of a mixture of bio-derived hexane produced from cellulose and naphtha in an aromatization process.

Abstract: This disclosure relates to the production of xylenes from syngas, in which the syngas is converted to an aromatic product by reaction with a Fischer-Tropsch catalyst and an aromatization catalyst. The Fischer-Tropsch catalyst and aromatization catalyst may be different catalysts or combined into a single catalyst. The aromatic product is then subjected to selective alkylation with methanol and/or carbon monoxide and hydrogen to increase its p-xylene content.
