제목 Role of CO2 in Aromatization of Isobutanol/Isopropanol over Metal/ZSM-5
초록     The value added aromatics from low alkane and bioalcohol are evoking much interests as well as the demand of aromatics due to the configuration change on petrochemistry induced by the shake or natural gas. The industrial developed the Cyclar process has been suffered because of the problem of serious coke formation whereas the Ga-ZSM-5 catalyst has high activity for aromatization from low alkanes. When CO2 was co-fed with alcohols, the decreased deactivation rates within higher aromatics yield were maintained because of the role of the CO2 as a scavenger of hydrogen formed during dehydrocyclization after dehydration of alcohols. These phenomena seems to be mainly due to the role of CO2 by removing hydrogen and reducing the coke formation and sustaining of metallic oxidation states during the aromatization. The Zn or Ga species on ZSM-5 could be enhanced the aromatic yield and to decrease the coke formation by CO2. The isobutanol could be one of the useful sources which convert into aromatics over metal/ZSM-5. We calculated energy states of CO2 and bioalcohols adsorbed on surface of metal/ZSM-5.
