摘要/Abstract

摘要：

为研究城市生活垃圾热解过程中不同组分交互作用对焦油特性的影响，将淀粉、聚氯乙烯（PVC）及其质量比为1：1的混合物在温度为400，500和600℃的条件下热解，对收集的焦油进行气相色谱-质谱联用（GC-MS）分析和凝胶渗透色谱（GPC）分析。结果表明，淀粉和PVC共热解时发生了交互作用，促进了更多重质组分和多环芳烃的生成，使焦油的分子质量大幅增加，增幅达44%～79%，且二者的交互作用在高温下更加显著。混合物与PVC的热解焦油呈现明显的相似性，在淀粉和PVC共同热解的过程中，PVC对焦油的生成起主导作用。此外，随热解温度的升高，焦油的产率和同质性均降低，而多环芳烃和重质组分含量增加。因此，二者共热解和较高的热解温度均能减少焦油产率，却也使生成的焦油更难以处理。

Abstract:

During the pyrolysis of municipal solid wastes, different components may interact with each other. In order to search the possible interaction on characteristics of tar, starch, polyvinyl chloride (PVC) and their mixture at the weight ratio of 1:1 were pyrolyzed at the temperatures of 400, 500 and 600℃. Gas chromatography-mass spectrometry (GC-MS) and gel permeation chromatography (GPC) analyses were adopted to characterize the collected tar. According to the results, interaction was occurred during the co-pyrolysis of starch and PVC, which enhanced the generation of heavier hydrocarbons and polycyclic aromatic hydrocarbons. The molecular weight of tar showed an obvious increase of 44%—79%. The interaction was more significant at a higher pyrolysis temperature. The tar derived from mixture showed great similarity with that derived from PVC, indicating that during the co-pyrolysis of starch and PVC, PVC was the dominant contributor with respect to tar formation. In addition, as the pyrolysis temperature arose from 400 to 600℃, the yield and homogeneity of tar both decreased while the contents of polycyclic aromatic hydrocarbons and heavier hydrocarbons increased. Therefore, the co-pyrolysis and high pyrolysis temperature both contributed to yield less tar, but the tar was more difficult to handle with.
