Revolutionizing Polymer Production: Breakthroughs in Iron Catalysis

The chemical industry continues to witness significant advancements in polymer synthesis, with remarkable progress in iron-catalyzed ethylene oligomerization for full ranges of alpha olefins with highly linear and pronounced vinyl-end products. This innovative approach is setting new standards for efficiency and sustainability in the field.

Key milestones achieved by Sinopec include:

• 50 Kt/a production line operating smoothly since September 2021 in Maoming.
• A groundbreaking 200 Kt/a facility launched in October 2024 in Tianjin.
• Ongoing construction of another 50 Kt/a Plant in Zhenhai, Ningbo.

These successes leverage proprietary technology, patented under ZL 2005 1 0066427.2 and ZL 2009 1 0236804.0, marking the debut of iron catalysts for highly linear polyethylene. This milestone underscores a significant leap in engineering plastics production, bridging academic research and industrial application.

As a collaboration between Sinopec and the Key Laboratory of Engineering Plastics, Institute of Chemistry, Chinese Academy of Sciences, these advancements highlight the potential of late-transition metal catalysts to redefine the future of polymer synthesis supported by parameters screening with Chemspeed's automated process reactor technology for catalyst synthesis.
