木薯燃料乙醇全生命周期CO_2排放分析——以循环经济为基础

摘要

Mitigating energy tension,reducing CO2 emissions of greenhouse gases isthe main purpose of developing new energy.According to"Reduce,Reuse,Recycle"as the guide,In the early course of study,the task of Fuel ethanol project is optimizing the production process of cassava fuel ethanolin whole life cycle,reducing the use of external carbon source,reusingthe wastefrom planting to the production process,making full use of carbonin cassava raw material,and realizing the carbon closed loopduring production process.Replaced the fossil energy of the original production process by recycling of waste,we can reduce the CO2 emission.%缓解能源紧张、减少CO2温室气体排放保护环境是发展新能源的主要目的。在燃料乙醇项目的前期研究过程中,以循环经济＂减量化、再利用、资源化＂为指导,优化木薯燃料乙醇全生命周期的生产工艺,减少使用外来碳源,资源化再利用从种植到生产过程中产生的废弃物,做到木薯原料中碳的＂吃干榨尽＂,生产环节实现碳的闭路循环。资源化再利用废弃物可替代原有生产工艺中化石能源的使用,以减少CO2的排放。
