The Bio-Alcohols were converted into value added products such as BTX and C9 Aromatics over Metallo ZSM-5 catalysts. The mechanism of aromatization includes dehydration, oligomerization, dehydrogenation, cyclization, and cycloaromatization according to the literatures. Among these complicated multi-steps, dehydrogenation step seems to be the biggest hurdle, in which CO2 is expected to be consumed by removing hydrogen and helps to form aromatic chemicals via Reverse Water Gas Shift Reaction (RWGS) of intruded CO2 and by-produced hydrogen. Aromatization reaction was run over various metallo ZSM-5 catalysts which include Ga and Zn under CO2 stream and the enhancements in aromatics yields were observed when CO2 was flowed in the catalysts. More CO was formed when olefin/paraffin ratio increased as CO2 consumes H2 in between, and it was also confirmed in RWGS reaction. |
