【摘要】 目前,生物质气化是我国为保护生态环境、充分利用农作物秸秆资源和实施可持续发展战略所重点推广的一项重大技术。本文主要对生物质气化系统净化后焦油的馏程、发热量、粘度、闪点、燃点、碳氢元素含量等热物理特性进行了实验研究,并根据实验结果探讨了焦油资源化利用途径和生物质燃气净化技术的原理,为设计开发出高效、适用的生物质焦油脱除与综合利用装置提供重要的科学参考依据,促进我国生物质气化技术的进程。更多还原

【Abstract】 Presently, the crop stalks-based biomass gasification and centralized gas-supply system isn’t still perfect in China. The main factors are:1) the purifier system having problems such as huge device, bas motion and low purifier efficiency so on; (2) bad disposal of tar causing the secondary pollution. For this reason, the distillation, calorific value and viscidity of the tar are analyzed and studied in this paper. From the experimental results the resources-utilization way of tar and the key technology of biomass gas purification are found. The technology not only can remove the tar and dust, but also can avoid the former system many shortcomings.更多还原
