Abstract:The reduction and harmless treatment of oily sludge is a challenging task. Microemulsion cleaning has been demonstrated to be an effective method to treat hazardous oily sludge. In this research,...
As China's oil consumption continues to increase, the amount of oily sludge generated increases yearly. Aiming at the limitations of the traditional oil-containing sludge treatment technology, supercritical water is used to dissolve and convert organic components into hydrogen for hydrogen energy recovery to realize the reduction, harmlessness, and resourcefulness of the oily sludge treatment. The influences of reaction temperature, pressure, time, material ratio, and other parameters on hydrogen production from supercritical water gasification of oily sludge were experimentally examined. Results indicated that hydrogen yield increases with increased response temperature, pressure, and time, and hydrogen yield decreases with increased response mass ratio.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
