Abstract

This research delves into the field of fast hydropyrolysis of mixed municipal solid waste (MSW), with the goal of understanding product distribution and interactions in a hydrogen-rich condition. Through experimental investigations on MSW and its components, this study thoroughly examines the impact of pyrolysis temperature and gasification atmosphere (30 % H2+30 % CO+20 % CO2+20 % H2O) on the yields and distribution of the three-phase products. As the temperature increases, the gas yield gradually increases, while the yields of tar and char gradually decrease. The introduction of a hydrogen source increases the methane content in the combustible gas, which generally reaches its maximum at 850 °C, and promotes aromatic formation in tar, making aromatics the main component of pyrolysis oil. Notably, aromatics have the highest-octane number in gasoline. This study highlights gasification as a promising technology for converting organic waste into valuable fuel, advancing waste management and energy recovery.

城市固体废物及其成分在蒸汽富氢合成气气氛下的高温快速热解特征、产物分布和相互作用效应的深入研究
本研究深入探讨了混合城市固体废物(MSW)的快速水热解领域,旨在了解富氢条件下的产物分布和相互作用。通过对城市固体废物及其成分的实验研究,本研究深入探讨了热解温度和气化气氛(30 % H2+30 % CO+20 % CO2+20 % H2O)对三相产物的产量和分布的影响。随着温度的升高,气体产量逐渐增加,而焦油和焦炭的产量则逐渐减少。氢源的引入增加了可燃气体中的甲烷含量,甲烷含量一般在 850 °C 时达到最大值,并促进焦油中芳烃的形成,使芳烃成为热解油的主要成分。值得注意的是,芳烃在汽油中的辛烷值最高。这项研究表明,气化技术是将有机废物转化为有价值燃料的一项前景广阔的技术,可促进废物管理和能源回收。
