Abstract
Polyolefins, including polyethylene (PE) and polypropylene (PP), are important high molecular weight plastics derived from olefins. They are used in various industrial and everyday uses due to their sustainability, low density and resistance to degradation. This paper reviews the development and current situation of polyolefin production methods emphasising the progress of the catalyst and polymerization process. The key process of synthesis of olefin, Fischer-Tropsch synthesis, is summarized, and its variation, low temperature method (LTFT) and high temperature method (HTFT), as well as the role of catalyst accelerator in improving the reaction efficiency and selectivity are discussed. Various polymerization techniques, including high pressure, low pressure and gas phase polymerization, have also been studied, each of which has unique advantages for the molecular weight and crystallinity of polyolefin. Notable advances include the development of Ziegler-Natta and supported metallocene catalysts, which have significantly improved polymer quality and production efficiency. Recent work has focused on improving sustainability through recycling, renewable raw materials, and creating biodegradable and functionalized polyolefins. Future directions emphasize the need for more efficient catalysts, reduced carbon emissions, and optimized processes to improve environmental and economic benefits. This comprehensive review highlights the progress and challenges facing the polyolefin production industry, highlighting its importance and the potential for future innovation.
