| 摘 要： | 在无氧环境下对黑液进行快速热解,获得液态的生物油和由碱金属盐类与炭结合组成的焦炭。结果表明:黑液快速热解将黑液中的木素转化为含丰富的酚类化合物的生物油,有利于黑液的资源化利用;生物油的GC-MS分析表明,其主要由10种酚类、6种酮类及5种不饱和烃类组成,其中酚类相对百分含量高达88.02%,是代替苯酚合成酚醛树脂胶黏剂的理想原料;理论上可以通过快速热解高效回收碱。

| Abstract: | Bio-oil and coke which is composed of char and alkali are obtained through the pyrolysis of black liquor.e results showed that:fast pyrolysis is conducive to the comprehensive utilization of black liquor,turning the lignin of black liquor into biooil that contains abundant phenols.GC-MS analysis proves that bio-oil is mainly composed of ten kinds of phenols,six types of ketones and five unsaturated hydrocarbons,including percentage content of phenols up to 88.02%.It is the best alternative of phenol to synthetic phenolic resin.eoretically,alkali can be efficiently recovered by fast pyrolysis. |
