Problems with polyethylene catalysts
Thread Content
I would like to ask: what is the actual catalytic capacity of current polyethylene slurry catalysts, in terms of tons per kilogram (for those that are already in use in production)? What is the optimal ratio between silica gel and furan? How much more room is there for improving the catalytic capacity of Th-1 solid catalysts? Thank you!
The yield of the slurry catalyst is approximately 7–10 t/kg (catalyst)
The slurry catalyst is currently in pilot production at Zibo XinSoo; the results are awaited. Shanghai Lide should also have its products ready by now. Replacing solids with slurries is a historical trend
Here, it’s roughly 12,000 to 15,000 kg of PE per kg of cat, while PP is around 40,000.
Shanghai Lide Catalyst Co., Ltd. produces solid slurry catalysts, whose quality reaches the level of imported catalysts.
The activity of the slurry catalyst TH-1LA produced by Zibo Xinsu is approximately 20,000 to 28,000 (KgPE/KgCAT), with a vulcanization density of 210 to 230 kg/m3
