Design of Transition-Metal/Zeolite Catalysts for Direct Conversion of Coal-derived CO2 to Aromatics
- Georgia Inst. of Technology, Atlanta, GA (United States). Georgia Tech Research Institute
This project introduces a lab-scale, stand-alone process to produce aromatics from CO2. Besides reducing the amount of coal-derived CO2 emission, this process can provide new approaches to produce valuable chemicals such as benzene, toluene, and xylene (BTX). These chemicals are the starting material in various industries such as pharmaceuticals, polymers, paints, and coatings. The focus of the project is on developing a suitable reaction configuration, feed composition, and catalyst combination that leads to high aromatics selectivity and CO2 conversions. To achieve these objectives, computational catalysis will accompany hands-on experiments to provide insights to potential transition metals or alloys that may serve as optimal active sites for different steps of the reaction mechanism, such as reduction of CO2 and dehydration (in the case of alcohol intermediates) and oligomerization (in the case of paraffins or olefins) of intermediate hydrocarbons.
