ООО "Химфист"

Currently, a wide range of FGWC has been created for various gas and liquid-phase processes, and industrial production of these catalysts has been organized.

The company guarantees 1-3 month's delivery time for any-size lot of FGWC.

FGWC has been certified by the State Certification Organization as "Silica fiberglass woven materials for catalysts" under certificateе №: TU RB 05780349-019-94.

In accordance with customers' requirements the company can supply FGWC doped by various catalytic active metals and their compositions such as Pt, Pd, Rh, Ag, Cr, Co, Ni, Cu, etc.

Silicate fiberglass materials have a long history of development and are widely applied as thermo and electro-isolating materials, or as the fillers in the fiberglass-polymer composites used as construction materials.
However, despite these materials are chemically relative with traditional for catalysis silica-gel carriers, the fiberglass woven articles were, for quite some time, unjustifiably ignored by specialists of fundamental and applied catalysis and these materials were not used in catalytic technology.
A basic technological concept of the Company was to join conventional fiberglass woven materials producing schemes with special operations to give catalytic properties to these materials. This method may be regarded as a principled new technological approach in technology of catalysts production.

Advantages:

Fiberglass woven catalysts have the follow advantages over traditional catalysts:

  • Reduced Operational Expenses and Capital Expenditures: Large-scale production of FGWC does not require considerable investments since it can be achieved on the basis of already existing technologies in the manufacturing of fiberglass and glass fabrics. Furthermore, FGWC production uses cheap fiberglass raw materials as opposed to traditional for industrial catalysis expensive ceramic materials.
  • Increased Catalytic Activity: FGWC exhibit extremely high catalytic activity and an easy-to-manage selectivity. This is achieved by a non-equilibrium phase state of fiberglass' amorphous matrix structure. This places these catalytic materials on a new level of catalyst quality.
  • Easy in Exploitation: FGWC composition allows realizing highly effective catalytic reactor designs. Specifically, FGWC technology moves you from traditionally bulky schemes of granulated catalysts to cassette oriented catalytic cartridges, easily installed and extracted without process interruption.
  • Transferring to uninterrupted schemes of catalysts production. FSWC production can be formed in easily re-configurable schemes: from the preparation of dry glass-melting mixtures to the packaging of ready rolls of catalyst material. This is in contrast to the periodic, multistage, energy-intensive traditional sol-gel technology.

FGWC applications areas, their technological and commercial effects:

Application Area Effect
1. Nitric acid production (Ammonia conversion on new catalytic systems as alternative to traditional Pt-gauzes) - Similar activity guarantees a reduction of Pt losses and inputs by anywhere from 2 to 10 times (i.e. 0,02- 0,06g Pt per ton of acid instead of traditional 0,12-0,15g).
2. Sulfuric Acid Production (Contact stage on fiberglass catalysts instead of vanadium-systems) - Reduction of contact temperatures by to 40-60°C;
- Improvement of ecology compatibility of the process (reduction of SO2 residual abundance in gas exhaust by 5-10 times);
- Increased stability regime, and exclusion of local emergency overheating;
- Cost cutting of catalyst per load by 10-20% and decreased catalytic material mass by 10-50 times
3. Industrial Gas Exhaust Neutralization - Simplified purification systems and price reduction by 2-3 times;
- Increased working resource and poison tolerance (absolute tolerance to sulfur-compounds)
4. Natural Oils and Fats Hydrogenation in Margarine Industry - Creation of inexpensive, filterless, ecologically clean technology;
- Uninterrupted production as a result of eliminated powder catalyst systems.
5. Aniline production by means of liquid- phase hydrogenation of nitrobenzene
6. Water Purification from nitrate/nitrite impurities
7. Purification from acetylene (ethylene, propylene, synthetic caoutchouc monomer production) - Costs reduction by 20-30%;
- Simplified cassette loading with 10-times less catalytic mass;
- Improved resources characteristics
8. Catalytic nitriding of steels and alloys (new process in machine-building industry) - New consuming characteristics of treated metal articles;
- Expanded range of metals for gas nitriding;
- Time reduction of nitriding process by 2-10 times.
