在实验室规模的感应加热反应器中，对松木锯屑及其主要组分木质素和纤维素进行了快速热解实验。测试了五种不同温度（500、550、600、650和700摄氏度）对产品产量和质量的影响。对产品进行了表征，以评估含水量、元素组成、化学组成和能量含量。对于所有的生物质，炭产率随温度的升高而降低。松木锯屑在600 ℃时的最大液体产率为55.28%，纤维素和木质素在500 ℃时的液体产率最高。随着反应温度的升高，液体馏分中的含水量降低。GC-MS分析表明，纤维素生物油中富含脱水糖，而木质素生物油中大部分含有较高的酚类物质。气体馏分的分析表明，随着温度的增加，气体产率增加，这与下降的焦炭质量配对时，显示出在较高温度下生物质分解的增加。来自松木屑的液体级分具有最高的HHV，峰值在550 ℃。(c)2016爱思唯尔有限公司版权所有
Fast pyrolysis of pinewood sawdust and two of its major components, namely lignin and cellulose was carried out using a laboratory scale induction-heating reactor. The effect of five different temperatures (500, 550, 600, 650 and 700 degrees C) was tested on the product yield and quality. The products were characterized to evaluate the water content, elemental composition, chemical composition and energy content. The char yield decreased with temperature for all of the biomasses. The maximum liquid yield of 55.28% was achieved at 600 degrees C for pine sawdust, and the highest liquid yields for cellulose and lignin were obtained at 500 degrees C. Water content in the liquid fraction decreased as reaction temperature increased. The GC-MS revealed that the bio-oil from cellulose was rich in anhydrosugars while majority of the liquid from lignin had high phenolic contents. Analysis of the gas fraction shows that as the temperature increases the gas yield increases, which, when paired with the declining char masses, showed an increase in the biomass breakdown at higher temperatures. Liquid fraction from pine sawdust has the highest HHV with a peak at 550 degrees C. (c) 2016 Elsevier Ltd. All rights reserved.
