Production and evaluation of hydrocarbon oil from co-deoxy-liquefaction of waste lard and locust leaves

► At 450 °C, 69.8% alkanes were detected with the lowest oxygen content of 1.4%. ► More saturated fatty acids and extractives favored formation of more alkanes. ► Nitrogen of locust leaves was partly converted into nitrogen gas. ► Preparation of hydrocarbon oil was highly related to biomass feedstock.
