Supercritical water gasification (SCWG) of waste cooking oil<\/strong><\/p>\n

Recently, Prof. JA Kozinski group at Waterloo collaborated with Profs. AK Dalai at U Saskatchewan and Zhen FANG studied SCWG of waste cooking oil.<\/p>\n

In the work, Dr. S Nanda (U Western Ontario) et al. studied waste cooking oil gasification at variable temperatures (375-675\u00b0C), feed concentration (25-40 wt%) and reaction time (15-60 min) to investigate their effects on syngas yield and composition. Maximum yields of hydrogen (5.16 mol\/kg) and total gases (10.5 mol\/kg) were obtained at optimal temperature, feed concentration and reaction time of 675\u00b0C, 25 wt% and 60 min, respectively. At 5 wt% loading, Ru\/Al2O3 enhanced hydrogen yield (10.16 mol\/kg) through water-gas shift reaction, whereas Ni\/Si-Al2O3 improved methane yield (8.15 mol\/kg) via methanation reaction. The trend of hydrogen production from catalytic supercritical water gasification of waste cooking oil at 675\u00b0C, 25 wt% and 60 min decreased as Ru\/Al2O3 > Ni\/Si-Al2O3 > K2CO3 > Na2CO3. The results indicate the recycling potential of waste cooking oil for hydrogen production through hydrothermal gasification.<\/p>\n
