Pyrolysis, one of the most promising thermal conversion technologies for biomass conversion, can decompose biomass into solid bio-char, liquid bio-oil, and combustible gas to meet different energy needs. However, pyrolysis efficiency and product quality are not as good as expected when raw biomass is used owing to the properties of raw biomass (e.g., high moisture, oxygen, and alkali metal contents). Torrefaction is an emerging biomass pretreatment technology that can improve the physical and chemical properties of raw biomass, and pyrolysis efficiency and final product quality can therefore be improved by using torrefied biomass. We review several advantages of pyrolysis of torrefied biomass in terms of the conversion process and final product quality.
热解是最有前途的生物质转化热技术之一，它可以将生物质分解为固体生物炭、液体生物油和可燃气体，以满足不同的能源需求。然而，由于原料生物质的特性（如高水分、高氧和高碱金属含量），直接使用生物质进行热解的效率和产品质量并不如预期。热解是一种新兴的生物质预处理技术，可以改善原料生物质的物理和化学性质，因此使用热解生物质可以提高热解效率和最终产品质量。我们从转化过程和最终产品质量两方面综述了热解热解生物质的几个优点。
