以典型的煤炭循环经济工业园为例,基于生命周期法对煤炭循环经济工业园的碳排放源进行追踪,构建了一种循环-低碳经济协同减排评价与决策模型。在此基础上核算了典型煤炭循环经济工业园整体CO2排放系数和煤炭循环经济减碳潜力,进而分析和评价了典型煤炭产业链的温室气体排放系数及煤炭循环经济减碳潜力。研究表明,煤炭循环经济的低碳价值占整体碳排放系数的7.81%,循环经济有一定减碳效果。同时研究指出煤炭利用环节CO2排放系数较高,提高煤炭的利用效率是整个煤炭循环经济工业园的减排方向;煤炭-煤化工产业链的温室气体排放系数较煤炭-电厂产业链的温室气体排放系数较低,科学适度地发展煤制甲醇技术在一定程度上可以缓解煤炭产业碳排放量的增长。
Taking a typical coal recycling economy industrial park as an example, the carbon emission sources of the coal recycling economy industrial park are traced based on the life cycle method, and a model for evaluation and decision-making on the cycle-low carbon economy collaborative emission reduction is constructed. On this basis, the overall CO2 emission coefficient and the carbon cycle potential of coal recycling economy in a typical coal recycling economy industrial park are calculated, and then the greenhouse gas emission coefficient of a typical coal industrial chain and the carbon reduction potential of the coal recycling economy are analyzed and evaluated. Research shows that the low-carbon value of the circular economy of coal accounts for 7.81% of the overall carbon emission coefficient, and the circular economy has a certain carbon reduction effect. At the same time, it is pointed out that the coefficient of CO2 emission of coal utilization is high, and the utilization efficiency of coal is the emission reduction direction of the whole coal recycling economy industrial park. The coefficient of greenhouse gas emission of the coal-coal chemical industry chain is lower than that of the coal-power plant industry chain Coefficient lower, scientific and moderate development of coal-methanol technology to a certain extent, can ease the coal industry’s carbon emissions growth.
