Tehmetall–2002 is the Russian leading company that produces vanadium catalysts for sulfurous gas oxidation. The quality of our catalysts is thoroughly tested and has the highest ratings done by the consumers as well as the leading experts in the catalysis field. Since 1942, extensive Research and Development work has been made in production, technologies, engineering of different catalyst modifications and dimension types to suit particular consumer requirements and to improve efficiency of the process and environment conditions.

Tehmetall–2002 has enormous work experience - 70 years - both on Russian and International markets and continues to develop the successful history of the company. Tehmetall-2002 manufactures vanadium catalysts using diatomite as a natural carrier. Diatomite, sourced from a world-renowned company IMERYS Filtration Minerals (World Minerals), has qualitative characteristics which are specially engineered for the oxidation of sulphur dioxide in the production of sulphuric acid. It also offers a wide range of brands and modifications of the highest quality.Tehmetall-2002 maintains close relations with its customers by providing high quality technical support. Our catalyst experts may assist with calculating catalyst loading and converter performance as well as evaluating technical conditions of sulphuric acid systems and monitoring catalyst performance to ensure that the ultimate catalyst and converter potential is achieved.

We cooperate with such key scientific institutes in Russia as The Research Institute for Mineral Fertilizers (NIUIF), D. Mendeleyev University of Chemical Technology and National Research University (St. Petersburg State Polytechnic University). The institutes provide us with scientific and technical assistance of catalyst production technologies.Our company products are supplied to more than 60 first-rate plants, both Russian and international, including companies in Belarus, the Ukraine, Uzbekistan, Kazakhstan, Korea, Azerbaijan, and India.

SVD (KD)

Shows best performance in the first two beds. Unique resistance to high temperature deactivation.

SVNT (KD)

A highly active catalyst in the 2nd, 3rd, 4th and 5th beds. It has high conversion parameters for budget catalyst loading.

I К A-1-6 SVP

Super Vanadium Pentoxide. The catalyst operates in low temperature. It is intended for the substitution of basic cesium promoted catalysts. For use in 4 and 5 beds of DC-DA converters. May also be loaded in the 3rd bed and at the top of the 1st bed. Resistant to low temperature deactivation.

SVD (K-D, K)

It is used as ignition layer and/or in the last bed for converson increase. Reduction of SO₂ emission (double absorption SAP) to 50-100 ppm.

SVD ( К -D, К ) SP

Super Cesium promoted. It is optimized to use in the last bed of a converter; maximum conversion is achieved. The SO₂ emissions (double absorption SAP) are reduced down to 50 ppm.
