This study employed HZSM-5 (SiO2/Al2O3 = 280 mol/ mol) to produce hydrocarbons from reagent-grade isopropanol and mixed alcohols made from lignocellulosic biomass (waste office paper and chicken manure) using the MixAlco (TM) process. All studies were performed at P=5000 kPa (abs). The experiments were conducted in two sets: (1) vary temperature (300-450 degrees C) at weight hourly space velocity (WHSV) 51.92 h 21, and (2) vary WHSV (1.92-11.52 h 21) at T=370 degrees C. For isopropanol at higher temperatures, the olefins undergo more cracking reactions to produce smaller molecules and more aromatics. At low temperatures, the molecules have less energy so they do not crack and therefore form larger molecules. At T=300 degrees C, the carbon distribution is bimodal at C9 and C12, which shows trimerization and tetramerization of propene. At 300 degrees C, propene was the only gas produced, cracking did not occur and therefore preserved high-molecular-weight molecules. For mixed alcohols, higher temperatures show significant catalyst deactivation; however, isopropanol did not show any catalyst deactivation. (C) 2016 American Institute of Chemical Engineers
