混合废塑料与煤共热解过程中氯的释放动力学研究

通过对混合废塑料与煤共热解的实验数据进行分析计算,推导出热解过程中氯在固(焦炭)、气(煤气)中的分布量与恒温时间、WP加入量之间的关系,建立了焦炭中氯的残留量的表观动力学方程,根据该方程可以计算达到某一残留量要求时,所需的恒温时间。同时也分析了煤气中氯的生成动力学方程,以及以上过程的表观活化能。 In this article,the emission dynamics of chlorine in the pyrolysis process of waste plastic and coal was studied.There are three products in the process of pyrolysis.They are coke(solid),tar(liquid),coal gas(gas).The relativity between distribution quantity of chlorine in this three products and time of constant temperature as well as percents of WP was determined,and the dynamic equations about them were founded by analyzing experimental date.Through comparing the rate constant of pyrolysis at 950℃ with at 600℃,the activity energy was calculated.Using those dynamic equations,we can calculate the time of constant temperature as requiring certain quantity of chlorine in coke
