Abstract

An investigation on the effect of pyrolysis parameters on the yield of pyrolytic bio-oil in the thermal degradation of water hyacinth was studied in a fixed bed reactor. The study revealed that maximum bio-oil yield of 44.5 wt % was realized at a reactor temperature, biomass particle size and nitrogen gas flow rate of 450 °C, 0.6 mm and 100 cm³/min, respectively. GC-MS analysis of the bio-oil detected phenols, alcohols, carboxylic acids, ketones, alkenes, alkanes, aldehydes and aromatics, which envisages that pyrolysis of water hyacinth could be a viable route for the production of renewable fuels and chemicals; and solve the problems of its invasions in our inland fresh water ways.

摘要

在固定床反应器中研究了热解参数对水葫芦热降解中热解生物油收率的影响。研究表明，在反应器温度、生物质粒径和氮气流速分别为 450 ℃、0.6 mm 和 100 cm ³ /min 时，实现了 44.5 wt% 的最大生物油产率。GC-MS 分析生物油检测到的酚、醇、羧酸、酮、烯烃、烷烃、醛和芳烃，设想水葫芦的热解可能是生产可再生燃料和化学品的可行途径；并解决其入侵我国内陆淡水途径的问题。
