Plastic waste has been growing every year, and as a result, environmental concern has been a topic of much attention. Many properties of plastics, such as their lightweight, durability, and versatility, are significant factors in achieving sustainable development. The exponential increase of plastic production produces every year approximately 100 million tons of waste plastic, which could be converted into hydrocarbon fuels by employing a process appropriately called pyrolysis. Pyrolysis, which is thermal or catalytical, can be performed under different experimental conditions that affect the type and amount of product obtained. With the pyrolysis process, products can be obtained with high added value, such as fuel oils and feedstock for new products. In this study, magnesium silicate (MgO₃Si) and Cloisite 30B were used as catalysts for the decomposition of different plastics, and the results were compared with the zeolite catalyst. In the case of high-density polyethylene (HDPE), the oil yield with a zeolite catalyst was found to be 71%, whereas with MgO₃Si and Cloisite 30B, this was 68% and 67%, respectively. Zeolite produced better results in the decomposition of polypropylene (PP) compared to MgO₃Si and Cloisite 30B. Fourier-transform infrared spectroscopy (FTIR), and gas chromatography (GC) were conducted in this work. The spectra results for all samples were consistent and in the fuel range.

塑料废料每年都在增长，因此，对环境的关注已成为备受关注的话题。塑料的许多特性，例如它们的轻质性，耐用性和多功能性，都是实现可持续发展的重要因素。塑料产量的指数级增长每年产生约1亿吨废塑料，这些废塑料可通过采用适当地称为热解的过程转化为碳氢燃料。热裂解或催化裂解可以在不同的实验条件下进行，这些条件会影响所得产物的类型和量。通过热解过程，可以获得高附加值的产品，例如燃料油和新产品的原料。在这项研究中，硅酸镁（MgO ₃Si）和Cloisite 30B被用作分解不同塑料的催化剂，并将结果与​​沸石催化剂进行了比较。在高密度聚乙烯（HDPE）的情况下，发现使用沸石催化剂的油产率为71％，而使用MgO ₃ Si和Cloisite 30B的油产率分别为68％和67％。与MgO ₃ Si和Cloisite 30B相比，沸石在聚丙烯（PP）分解中产生了更好的结果。在这项工作中进行了傅里叶变换红外光谱（FTIR）和气相色谱（GC）。所有样品的光谱结果均一致且在燃油范围内。
