Two-Stage Catalytic Conversion of Carbon Dioxide Into Aromatics Via Methane.

ABSTRACT: In the refinery of the future, the input shifts from crude oil to biomass, plastic, and CO₂. Therefore, we need to find alternative routes to produce chemical building blocks, such as aromatics, which are used in products like, for example, fuels. In this study, we investigated a two-stage route to produce benzene from CO₂. In two sequential reactions, CO₂ is first converted into methane over a Ni/TiO₂ catalyst, and methane is further reacted to yield benzene using a Mo/ZSM-5 catalyst via the methane dehydroaromatization (MDA) reaction. Through a combination of thermodynamic calculations and experiments, we found the goldilocks conditions for performing this two-stage process. The unreacted CO₂ and H₂ from the first reaction
