含氮生物质超临界水气化研究进展

Research progress on supercritical water gasification of nitrogen-containing biomass

废弃生物质的超临界水气化制氢备受关注,而大多数废弃生物质均含氮元素,其残留在液固相产物中会显著影响后续处理。综述了几种典型含氮生物质(污泥、蓝藻等)的超临界水气化研究现状;总结了氮元素在超临界水气化过程中的分布与转化研究进展;最后对其研究前景和发展方向进行了展望,以期未来可对超临界水气化过程中的氮元素进行更加精确的靶向调控,进一步对含氮生物质进行无害化处理。

The supercritical water gasification of waste biomass has attracted much attention,while most waste biomass contains N element,and its residue in liquid-solid products will significantly affect the subsequent treatment of the products.Therefore,this paper summarizes the research status of supercritical water gasification of several typical nitrogen-containing biomass(sludge,cyanobacteria,etc.)and the distribution and transformation of nitrogen elements in the process of supercritical water gasification.Finally,the research prospect and development direction are prospected in order to control nitrogen elements more accurately and further treat nitrogen-containing biomass innocuously.
