摘要：
Crofton weed is an invasive alien plant which is causing significant economic and environmental losses in China. The purpose of this study is to evaluate the applicability of deoxy-liquefaction reaction to the utilization of Crofton weed. Deoxy-liquefaction experiments of two different sections (leaves and stems) and the whole plant of Crofton weed were performed at six different temperatures (375-500 degrees C). Oils with low oxygen contents (< 8 wt%) and high HHVs (> 40 MJ/kg) were obtained. 425 degrees C was the optimum temperature for obtaining oil from Crofton weed. Besides, solid chars with high HHVs of about 20 MJ/kg were obtained. Gases with HHVs ranging from 1.6 to 5.7 MJ/mol were produced. The overall energy recovery of the system was estimated at about 70%. (C) 2011 Elsevier B.V. All rights reserved.
