Who knows what catalysts are used for ethylene and propylene polymerization at Baotou Shenhua?
Thread Content
Guys, does anyone know what catalysts are used in the processes of polymerizing ethylene to produce polyethylene, and polymerizing propylene to produce polypropylene in the methanol-to-olefins plants operated by Baotou Shenhua? If you know, please let me know. Thank you!
Both polyethylene and polypropylene are produced using the Unipal process: polyethylene is manufactured via Univation’s process, while polypropylene is produced using Dow Chemical’s process. At this stage, catalysts from the respective patent holders are definitely being used； It’s hard to say the specific model, as each grade of polyethylene and polypropylene catalyst is different. So it’s difficult to answer your question; if answered in detail, it would reveal trade secrets!
