In the present paper, LDPE has been pyrolysed in a 1 m length semi pilot reactor at temperature range 550–650 °C for around 2 h. Commercial bentonite, kaoline, silica Gel and activated charcoal have been used as catalyst. Liquid, gas and solid fractions (residue) were quantified. Effects of pyrolysis temperature and catalysts on liquid product were investigated. It was found that using catalyst gave shorter dripping time and this dripping started at a lower temperature. PIONA analysis of liquid product has been carried out and the highest percentage of olefins was found on using bentonite as a catalyst.

使用催化剂混合物对低密度聚乙烯废塑料进行热解

在本文中，LDPE已在长度为1 m的半中试反应器中在550–650°C的温度范围内热解了约2 h。商业膨润土，高岭土，硅胶和活性炭已用作催化剂。量化液体，气体和固体部分（残渣）。研究了热解温度和催化剂对液体产物的影响。发现使用催化剂使滴落时间更短，并且该滴落在较低的温度下开始。已经对液体产物进行了PIONA分析，并且使用膨润土作为催化剂发现了最高百分比的烯烃。
