生物质快速热解在欧洲引起了迅速增长的兴趣，因为它被认为提供了显着的物流优势，因此比其他热转化过程的经济优势。这是因为液体产品可以储存直到需要或容易地运输到可以最有效地利用的地方。本文的目的是审查所面临的快速热解，升级和利用过程的开发商，以成功地实施这些技术的设计考虑。快速热解系统的设计方面包括进料干燥;粒度;预处理;反应器配置;供热;传热;加热速率;反应温度;蒸气停留时间;二次裂化;焦炭分离;灰分分离;液体收集。每一个这些方面进行审查和讨论。案例研究显示了该技术在废木材中的应用，以及这种方法如何很好地控制污染物。最后，通过对生物油的呼吸测试来解决溢出问题，最后总结了快速热解对全球变暖的潜在贡献。(C)1999 Elsevier Science Ltd.保留所有权利。
Biomass fast pyrolysis is of rapidly growing interest in Europe as it is perceived to offer significant logistical and hence economic advantages over other thermal conversion processes. This is because the liquid product can be stored until required or readily transported to where it can be most effectively utilised. The objective of this paper is to review the design considerations faced by the developers of fast pyrolysis, upgrading and utilisation processes in order to successfully implement the technologies. Aspects of design of a fast pyrolysis system include feed drying; particle size; pretreatment; reactor configuration; heat supply; heat transfer; heating rates; reaction temperature; vapour residence time; secondary cracking; char separation; ash separation; liquids collection. Each of these aspects is reviewed and discussed. A case study shows the application of the technology to waste wood and how this approach gives very good control of contaminants. Finally the problem of spillage is addressed through respirometric tests on bio-oils concluding with a summary of the potential contribution that fast pyrolysis can make to global warming.
