对现有的快速热解工艺技术进行了简要综述。结果表明，在大多数情况下，只要满足一定的加热速度和停留时间标准，就可以得到类似的产品。重点是在中等温度和相对较短的停留时间条件下进行热解，以获得高液体产率。概述了原料来源和预处理的影响。将与科学文献的结果进行比较。将考察改变和提高产物产率的特异性的可能性程度。将介绍和分析已提出的和可能解释已报道的实验产品光谱的热解机理。最后，基于目前已知的化学和技术，将提出未来的替代方案和可能性。
Existing technology for fast pyrolysis processes will be reviewed briefly. It will be shown that in most cases, provided certain criteria of heating rate and residence time are met, similar products will be obtained. The emphasis will be on pyrolysis in the regime of moderate temperatures and relatively short residence times which leads to high liquid yields.Effects due to the source and pretreatment of feedstocks will be outlined. Comparisons will be made with results from the scientific literature. The extent to which it is possible to alter and increase the specificity of product yields will be examined.Pyrolytic mechanisms which have been proposed and which might account for the reported experimental product spectra will be presented and analysed.Finally, based on the presently known chemistry and technology, future alternatives and possibilities will be suggested.
