. This catalyst produced 53.94 wt% of total liquid product that contained 1.31 wt% oxygenated compounds and 52.63 wt% biohydrocarbon that consisted of gasoline and diesel oil fractions of 23.10 and 29.53 wt%. After three hydrocracking runs, Co/BSA produced 36.15 wt% liquid product that contained 2.27 wt% oxygenated compounds and 33.88 wt% biohydrocarbon which consisted of gasoline and diesel oil of 20.87 and 13.01 wt%. |
