生物质水热转化技术作为一种新的生物质利用技术,在亚临界或超临界水下,将生物质直接转化为高品位气态、液态和固态产物.该技术具有原料适应性广、低成本和高转化率等特点,具有很好的应用前景.文章综述了近年来生物质水热技术研究的最新进展,分别对水热液化、水热气化和水热碳化3方面内容进行分析,对目前存在的问题提出了建设性的意见.%Hydrothermal biomass conversion, as an alternative way for biomass utilization, is a kind of technology that transforms biomass directly into high-grade gas, liquid and solid fuels in critical sub-or supercritical water. The technology has good raw material adaptability, low cost , high conversion efficiency, and has good application prospects. In this paper, the latest research status of hydrothermal biomass conversion was summarized. The three aspects, which are hydrothermal liquefaction (HTL), hydrothermal gasification (HTG) and hydrothermal carbonization (HTC) are analyzed. At last, it also puts forward methods to solve the existing problems.
