摘要

摘要: 采用离子色谱等方法测定了不同热解条件下液体产物（包括焦油和水）中氯的质量分数，讨论了影响煤与废塑料共热解过程中，热解温度、恒温时间、升温速率及气体流量等因素对液体产物中氯质量分数的影响。并通过红外光谱、离子色谱等手段分析了液体产物中氯的赋存形态。结果表明，煤热解过程中加入一定量的废塑料，并没有给焦油中带来大量的有机含氯化合物，但增加了焦油的产率，同时降低了水的产率。水中氯主要以无机盐（NH₄Cl）和有机胺类盐酸盐等含氯化合物的形式存在；焦油的红外光谱中没有明显的C—Cl吸收峰，说明焦油中有机氯的含量非常少。

Abstract: The occurrence mode and concentration of chlorine in liquid product including tar and water from co-pyrolysis of waste plastic (WP) and coal were studied. The effect of temperature, holding time, heating rate and gas flow on chlorine concentration in liquid product was examined. The result indicates that the addition of WP to coal in co-pyrolysis does not increase the organic chlorine compound in the liquid product. However, the tar yield increases, and the water yield decreases. The chlorine in water mainly exists as inorganic form (NH₄Cl) and organic amine hydrochloride. There is no obvious C—Cl band in IR spectra of tar is observed. This indicates that the organic chlorine in tar is very little.
