煤基甲醇产品的全生命周期评价

In this paper, we establish life cycle assessment boundary of coal-based methanol which contains both product life cycle and process life cycle. We analyze global warming, acidification, photochemical oxidant formation and human toxicity of environmental emissions of the coal-based methanol according to the boundary established and find out the weak link of each stage. The life cycle assessment is able to conclude comprehensive options to solve these questions in respect of technology and environment.
