Cr- and Ga-Modified ZSM-5 Catalyst for the Production of Renewable BTX from Bioethanol.

Light aromatics (benzene, toluene, and xylene, collectively known as BTX) are essential commodity chemicals in the petrochemical industry. The present study examines the aromatization of bioethanol with Cr- and Ga-modified ZSM-5. Both Cr and Ga were incorporated by the ion-exchange method.
