热解为生物质的高价值利用创造了许多（并将打开更多的可能性）。为了获得最佳量的所需热解产物，尤其是高质量的生物油，在过去的几十年中，学术界都进行了大量努力，以阐明生物质热解的基本机理并设计有效的相关技术流程。本文全面回顾了生物质热解的基础研究和技术应用的最新进展。首先，讨论了真实生物质及其主要成分的热解机理，反应器规模的生物质热解模拟以及热解产物的应用。然后，根据为改善各种热解产物的理化性质而提出的要求，综述了生物质热解工艺的相关优化和调控方法。先前的研究表明，生物质与其他原料的共分解不仅可以增强热解产物的理化特性，而且可以有效地实现废物的循环利用。因此，本综述涵盖了对使用四种不同原料（即煤，塑料，轮胎和污泥）进行生物质分解的最新进展的深入讨论。作为一般生物质热解必不可少的组成部分，还概述了催化生物质热解的最新活动，包括新的催化热解工艺，例如催化加氢热解和催化共分解。此外，还介绍了用于生物质热解的两种新颖的加热方法（微波加热和太阳能加热），并且将它们的特征与常规加热方法进行比较。最后，本文对生物质热解的未来发展方向进行了展望。

A Review of Recent Advances in Biomass Pyrolysis

Pyrolysis has created many (and will open more) possibilities for high-value utilization of biomass. To obtain the optimal amount of desired pyrolysis products, especially high-quality bio-oil, a great deal of effort has been conducted in both academia in the past few decades, to clarify fundamental mechanisms of biomass pyrolysis and design efficient relevant technical processes. This paper comprehensively reviews recent advances in both fundamental studies and technology applications of biomass pyrolysis. First, pyrolysis mechanisms of real biomass and its major components, the reactor-scale simulation of biomass pyrolysis, and applications of pyrolysis products are discussed. Then, according to the requirements imposed to improve the physicochemical properties of respective pyrolysis products, relevant optimization and regulation methods for biomass pyrolysis process are reviewed. Previous research has indicated that biomass copyrolysis with other feedstock can not only enhance physicochemical properties of pyrolysis products but also effectively realize recycling of wastes. Thus, an in-depth discussion of recent advances in biomass copyrolysis with four different feedstocks (i.e., coal, plastics, tires, and sludge) is covered in this Review. As an indispensable component of general biomass pyrolysis, recent activities of catalytic biomass pyrolysis are also summarized, including new catalytic pyrolysis processes such as catalytic hydropyrolysis and catalytic copyrolysis. Besides, two novel heating approaches (microwave heating and solar heating) for biomass pyrolysis are described, and their features are compared with the conventional heating method. Finally, this Review is concluded with perspectives for future directions of biomass pyrolysis.
