Abstract

Abstract: The organic waste is rich in hydrogen and carbon. It can be used as gasification raw material to produce synthetic raw gas with advantages of process cleaning and hydrocarbon recovery. There are many obstacles to overcome on converting organic waste to synthetic gas are needed,such as narrow range of organic waste gasification materials,difficulty of adapting to the large differences in the nature of organic waste,limiting gasification technologies in the field of organic waste treatment. According to different characteristics of the domestic industrial organic waste,animproved multicomponent slurry gasification (MCSG) technology for the organic waste is proposed in this paper. The basic principle of organic waste treatment was briefly discussed. Different treatment process route taken for different organic wastes and key equipment were introduced. Economy and technology for industrial applications were analyzed in this paper. The studies showed that the improved MCSG technology not only achieved the organic waste cleaning and reuse,but also had strong adaptability to the organic waste,and helped environmental protection,and provided economic benefits.

摘要： 有机废弃物中含有丰富的碳氢元素，相对于常规焚烧等处理方式，将其作为气化原料生产合成原料气具有过程清洁和可实现碳氢资源回用的优点，但目前相关的研究存在有机废弃物气化原料范围窄、难以适应有机废弃物性质差异大的问题，限制了气化技术在有机废弃物处理领域的应用。本文针对国内工业有机废弃物的不同特性，提出了一种改进型的有机废弃物多元料浆气化（multicomponent slurry gasification，MCSG）利用技术，简述了有机废弃物处理的基本原理，介绍了在面对不同特性有机废弃物时采取的不同处理工艺路线以及相配套的关键设备，分析了技术经济性以及工业化应用情况。结果表明利用改进型的多元料浆气化技术不仅能实现对有机废弃物的清洁和资源化回用，还对有机废弃物具有很强的适应性，同时具有良好的环保效益和经济效益，将会是一条未来实现我国工业有机废弃物处理绿色化发展目标的有效途径。
