酸预处理对生物质快速热裂解产物的影响
The effects of acid pretreatment on fast pyrolysis of lignocellulosic biomass
摘要
Abstract
Southern yellow pine wood flour was applied for this study. Three types of inorganic acids were selected as treatment reagent. Pretreated biomass and control samples were tested by Py-GC/MS to obtain chemical products yield after pyrolysis. The conditions for pyrolysis and pretreatment were optimized to maximize levoglucosan production during fast pyrolysis. The inorganic minerals content (Ca2+, Mg2+, K+and Na+)was measured to study the effects of acid pretreatment on fast pyrolysis of biomass. It was found that acid pretreatment removed most of the inorganic minerals content from raw pine wood flour. Acid pretreatments performed in this study significantly increased levoglucosan production and decreased levoglucosenone production during fast pyrolysis. Among three types of inorganic acids tested in this study, phosphoric acid pretreatment gave the highest yield of levoglucosan (20.5％) and lowest yields of acetic acid and 2-methoxy-4-propyl-phenol.关键词
