Abstract

FeOOH/AC-, FeOOH/Al2O3- and FeOOH/ZnO-supported catalysts were synthesized by immersion, hydrothermal hydrolysis, and hydrothermal methods, and used for supercritical water gasification (SCWG) of oily sludge. Under the same conditions, compared to FeOOH/Al2O3 and FeOOH/ZnO, the catalytic effect of FeOOH/AC was superior. When the concentration is 5% and the loading is 10%, the hydrogen production rate with FeOOH/AC composite is the highest, which is 4.638 mmol/g, and the hydrogen gasification efficiency (HE) is 89.50%. The reaction mechanism of FeOOH composites in the SCWG was also investigated. These results indicate that FeOOH composites are potential catalysts for oily sludge treatment.
