Abstract Biomass pyrolysis processes for bio-oil production were commonly done using batch, semi-continuous or continuous process. However, past studies have shown many concerning issues in regard to the use of batch process such as high residence time, product inconsistencies across batches, high labor cost and difficulty in industrial scale up. With these, scientists are now placing a greater interest and focus in the study of semi-continuous and continuous pyrolysis processes with their commercialization and industrialization as the major outcomes. The production rates of semi-continuous and continuous pyrolysis process are certainly more superior to the former owing to their facile in-situ withdrawal of products during pyrolysis. Nevertheless, they are of higher design complexities, thus requiring a better controllability of the operating parameters. This article reviewed on semi-continuous and continuous pyrolysis process through several perspectives: feed treatment, feeding system, operating parameters, reactor technologies and additional product separation devices. The expressed contents of this review will provide an understanding of the technical aspect of pyrolysis process comprehensively, starting from the material treatment to the end of product collection.

生物质半连续和连续热解制生物油技术综述

摘要 用于生物油生产的生物质热解工艺通常使用间歇、半连续或连续工艺进行。然而，过去的研究表明，使用批处理过程存在许多相关问题，例如停留时间长、批次产品不一致、劳动力成本高和工业规模化困难。有了这些，科学家们现在对以商业化和工业化为主要成果的半连续和连续热解过程的研究产生了更大的兴趣和重点。半连续和连续热解过程的生产率肯定优于前者，因为它们在热解过程中易于原位取出产品。然而，它们具有更高的设计复杂性，因此需要更好的操作参数可控性。本文从进料处理、进料系统、操作参数、反应器技术和附加产品分离装置几个方面对半连续和连续热解工艺进行了综述。本综述所表达的内容将全面了解热解过程的技术方面，从材料处理开始到产品收集结束。
