Hydrothermal catalytic processing of waste cooking oil for hydrogen-rich syngas production

Substantial amounts of waste cooking oil are obtained worldwide from household and catering enterprises because of deep-frying and other cooking activities. Supercritical water gasification is considered as an aqueous phase reforming process to produce hydrogen enriched syngas from biomass and other organic wastes. In this study, waste cooking oil was gasified at variable temperatures (375–675 °C), feed concentration (25–40 wt%) and reaction...
