Abstract

Pyrolysis is one way to minimise plastic waste. This process requires a catalyst such as zeolite. Natural zeolite needs to be activated to increase its catalytic activity. Therefore, this research was carried out by activating Ende's natural zeolite using 1% hydrofluoric acid (HF), 6M hydrochloric acid (HCl), and 1M ammonium chloride (NH4Cl) to be used as catalysts in the pyrolysis of polyethylene from plastic waste. Pyrolysis was carried out at operating temperatures of 300 oC, 350 oC, 400 oC, and 450 oC, and treated with a catalyst composition of 0%, 5%, 10%, and 15% from 1000 grams of polyethylene. Based on the results of the study, it was concluded that activation of Ende's natural zeolite could change the chemical and physical properties of Ende's natural zeolite, including crystallinity, surface area, pore volume, and pore radius, and acidity to serve as a catalyst. Treatment of 10% catalyst from 1000 mg of plastic at an operating temperature of 400oC reduced the activation energy to 4.371.1 cal/mol and produced 80% more paraffin fraction in polyethylene pyrolysis oil from plastic waste.
对硝酸盐的利用是聚乙烯聚乙烯泡沫的催化剂
热解是减少塑料垃圾的一种方法。这一过程需要沸石等催化剂。天然沸石需要经过活化才能提高其催化活性。因此,本研究采用1%氢氟酸(HF)、6M盐酸(HCl)、1M氯化铵(NH4Cl)活化恩德天然沸石作为催化剂,对塑料废弃物中的聚乙烯进行热解。热解在300℃、350℃、400℃和450℃的操作温度下进行,催化剂组成分别为0%、5%、10%和15%,催化剂来自1000克聚乙烯。根据研究结果得出,活化恩德天然沸石可以改变恩德天然沸石的化学和物理性质,包括结晶度、比表面积、孔体积、孔半径和酸度,从而起到催化剂的作用。在400℃的操作温度下,1000 mg塑料中添加10%的催化剂,使活化能降至4.371.1 cal/mol,废塑料中聚乙烯热解油的石蜡馏分提高80%。
