小球藻脂质富集与催化热解制备低氮生物油的协同增效机制研究
Research on the synergistic mechanism of exogenous induction of Chlorella lipid accumulation and catalytic pyrolysis for deoxygenation and denitrogenation of bio-oil
摘要
Abstract
Against the backdrop of the rapid industrialization worldwide,energy shortages and environmental pollution have become increasingly severe,making the search for sustainable alternative energy sources an urgent priority.Microalgae are considered an important source of biofuels due to their inherent advantages.This study explores the synergy between exogenous antibiotics and metal-loaded HZSM-5 catalysts in the denitrogenation and deoxygenation of bio-oil by optimizing Chlorella cultivation conditions.The results indicate that appropriate exogenous antibiotics significantly enhance the lipid content of Chlorella.Specifically,the lipid content reached 16.3％under 0.2 mg/L CTC(Chlortetracycline hydrochloride)treatment,which was 1.5 times higher than that of the control group.During the catalytic pyrolysis phase,the Ni/HZSM-5 catalyst exhibited the best performance in deoxygenation and denitrogenation reactions.When the catalyst-to-algal powder mass ratio was 1∶2,the oxygen and nitrogen content of the bio-oil decreased to 9.78％and 3.56％,representing a reduction of 30.5％and 30.8％compared to the CTC group.These results demonstrate superior fuel characteristics.This research provides scientific evidence and practical guidance for the resource utilization of microalgae-based biomass and the preparation of high-quality biofuels.关键词
