Catalysts Production and Supply

Production and supply of commercial catalysts

SIE Neftehim, LLC is a developer, manufacturer, and supplier of commercial catalysts for isomerization, reforming, normalization (reverse isomerization) of isobutane and isopentane; catalysts for hydrotreatment, methanation, hydrogenation of benzene; and other catalysts for oil processing and petrochemistry.

Catalysts are produced at the subsidiary company Nizhegorodskiye catalysts LLC (located in Nizhniy Novgorod, Russia) on modern process equipment. The production technology and the recipe of the catalysts are protected with patents and patent applications in Russia, European Union, China, India, and other countries.

Continuous quality control through all the production stages ensures high quality of catalysts that meet international standards.

Each industrial lot of the catalysts is analyzed and tested in the scientific and research laboratory of SIE Neftehim, LLC, where the processes can be simulated in conditions nearest to the industrial ones.

The catalysts are delivered all over the world, in compliance with international requirements and standards. At a client`s request, the shipments can be additionally audited by an independent international expert during the loading and dispatch operations.

SIE Neftehim, LLC is continuously improving the quality of the products to gain the best operating results and to enhance the service life of the commercial catalysts.
