In this work low temperature conversion (LTC) process was applied in a dried sludge from a petrochemical industry wastewater treatment station located in Rio de Janeiro, Brazil. The process was performed in two modes: continuous and batch-scale. This process produced a pyrolysis oil (continuous 14%; batch-scale 40% yield); pyrolytic char (continuous 46%; batch-scale 56% yield); gas and water. Pyrolysis oil fraction was analyzed by gas chromatographic mass spectrometry (GCMS) and the main components identified were toluene, ethylbenzene, styrene, isopropyl benzene, alpha-methylstyrene, butanenitrile and 1,3- biphenyl propane. Metals content, sulfur content and calorific value have been determined for the pyrolysis oil fraction. The results showed that the pyrolysis oil obtained could be used for industrial purposes and/or as energetic matrix.
在这项工作中，低温转化（LTC）工艺应用于巴西里约热内卢一家石化工业废水处理站的干污泥。该工艺以两种模式进行：连续模式和间歇规模模式。此工艺产生了热解油（连续模式下产率为14%；间歇规模模式下产率为40%）、热解炭（连续模式下产率为46%；间歇规模模式下产率为56%）、气体和水。通过气相色谱 - 质谱联用仪（GCMS）对热解油馏分进行了分析，鉴定出的主要成分有甲苯、乙苯、苯乙烯、异丙苯、α - 甲基苯乙烯、丁腈和1,3 - 联苯丙烷。已测定了热解油馏分的金属含量、硫含量和热值。结果表明，所获得的热解油可用于工业用途和/或作为能源基质。
