TOP provides molecular sieve technologies, products and services in olefinic hydrocarbon industry.

Molecular sieve adsorbents are used in all Ethene manufacturers all over the world. TOP’s innovative molecular sieve adsorbents are making new contribution to the development of Ethene manufacturers.

The purification of olefin streams for polymer plant feedstock is extremely demanding, requiring advanced adsorbents and technology to protect polymerization catalysts and achieve the highest grade of polyolefin products and properties. You can rely on TOP’s adsorbent products for effective dehydration of highly reactive petrochemical streams from ethylene to styrene. The demanding requirements of polymer grade monomer products can be met by TOP’s using specialty adsorbents. Our products can handle trace contaminant removal in many processes from regenerative adsorbents for sulfur and nitrogen compounds to oxygenate and mercury, to adsorbents for solvents and co-monomer steams, as well as non-regenerative adsorbents for arsine and sulfur compounds.
