Abstract:
... The characteristics of biochar produced from the co-pyrolysis of corn stalk (CS) and mulch film (MF) were analyzed. Cellulose, hemicellulose, lignin were applied to explore the synergistic effects of CS and MF during co-pyrolysis. Upon increasing the proportion of MF, the yield of liquid products increased, and the yield of solid products decreased. Interactions of cellulose, hemicelluloses, and li ...

Abstract:
... Oil pollution is causing deleterious damage to aquatic ecosystems and human health. The utilization of agricultural waste such as corn stalk (CS) to produce biosorbents has been considered an ecofriendly and efficient approach for removing oil. However, most previous studies focused on the modification of the whole CS, which is inefficient due to the heterogeneity of CS. In this study, corn stalk ...
