摘要: This study developed an upgrading process focusing on acid transformations of water phase pyrolysis bio-oils to esters oxygen-containing fuels via ZSM−5 catalyst. Temperature was set as a factor with five levels ranging from 60 135 °C reaction time 1 8 h. The results showed that 89% high conversion and over 90% ester selectivity obtained the feedstock 2 wt % catalysts in fixed methanol ratio analyzed by HPLC GC–MS. followed Langmuir–Hinshelwood constants were calculated build practical model for bio-oil compounds. Thermodynamics endothermic properties during breaking bonds’ carbonyl while between carbon electrophile intermediate demonstrated exothermic performance. optimum conditions at temperature 100.1 catalyst loading 3.98 %.
