MOSCOW (MRC) -- SIBUR (Moscow, Russia) says it is developing and testing a catalyst for use in the production of linear alpha-olefins as part of the company’s strategic program to strengthen its technological independence, said the company.
Pilot tests have taken place for the use of zirconium tetra-isobutyrate, with the catalyst developed by specialists from Sibur’s NIOST research center at Tomsk and the Nizhnekamskneftekhim Scientific and Technical Center (STC), it says.
SIBUR , Russia’s largest producer of petrochemicals and plastics, plans to build a production plant with a catalyst capacity of 50,000 metric tons/year by 2024 at Nizhnekamskneftekhim (Nizhnekamsk, Tatarstan, Russia), it says. Zirconium tetra-isobutyrate and hexene are mandatory components in the polyethylene (PE) production chain, enabling the manufacture of special polymer grades with improved properties for sectors including medical products, packaging materials, and gas and water supply systems, according to the company.
Domestic production by SIBUR of key components in small- and medium-tonnage chemicals is a “necessary element in maintaining the stability of the main technological chains,” it says. The company recently announced the development and testing of hexene, another key component for the production of polymers, with plans to build a 50,000-metric tons/year plant, also at Nizhnekamsk, with start of operations planned in the second half of 2024. Hexene is used in the production of high- and low-density polyethylene.
We remind, SIBUR has launched production of PET granules using recycled feedstock. The new product, Vivilen rPET granules, contains up to 25–30% recycled polymers and will now be manufactured at POLIEF, said the company.
Once the facility reaches its design capacity, each year POLIEF will be able to produce up to 144,000 tonnes of Vivilen PET granules with a share of recycled content.
