In this investigation, the effect of operating parameters on product distribution for the conversion of water hyacinth into most valuable product bio oil as well as char and gases are investigated. To observe the parametric effect on product distribution, the temperature was varied 300-600 °C, heating rate 10-50 °C/min, particle size of the feed <0.5-2.5 mm and carrier gas nitrogen flow rate 0-12 lpm. The highest bio-oil yield of 44.9 wt% was obtained at 350 °C, 30 °C/min, particle feed size less than 0.5 mm and 6 lpm. The results show that the product yield is strongly influenced by the temperature variation whereas weakly affected by the heating rate. The biomass and the products were characterized by ultimate, proximate, DTG, FTIR, H NMR, and GC-MS. Syngas evolution increase with the increase of temperature except CO. The quality of bio-oil is perspective as a source of value-added chemicals and char is a promising source for the production of carbonaceous materials as well as solid fuel.
本研究考察了不同操作参数对水葫芦转化为最有价值产品生物油、炭和气体的产物分布的影响。为了观察参数对产物分布的影响，温度范围为 300-600°C，升温速率为 10-50°C/min，进料粒径<0.5-2.5mm，载气氮气流量为 0-12lpm。在 350°C、30°C/min、进料粒径小于 0.5mm 和 6lpm 时，生物油收率最高，为 44.9wt%。结果表明，产物收率受温度变化的影响较大，而受升温速率的影响较小。采用元素分析、工业分析、DTG、FTIR、H NMR 和 GC-MS 对生物质和产物进行了表征。除 CO 外，随着温度的升高，合成气的产率增加。生物油质量有望成为附加值化学品的来源，炭是生产碳素材料和固体燃料的有前途的原料。
