Inert Bed Support & Topping

Proper packing of the catalyst in the converter and protecting the catalyst bed from external impurities are essential for obtaining efficiency. Alumina balls, lumps, rings, pellets etc., used as bed toppings and bed supports act as filters to remove many impurities from the gas stream and help in uniform distribution of the feed gas. Layers of these materials on top and bottom of the catalyst bed, keep the bed intact during pressure fluctuations. Hence, it survives depressurization, maintains its integrity and does not crack, break or shatter under severe environment. The product uniformity is extremely important for optimization of all aspects of catalyst in a reaction.

Petrogas bed support and topping have excellent product uniformity, which is achieved by careful selection of raw materials, precise manufacturing techniques and consistent quality control. We manufacture high, medium and low purity alumina products strictly in accordance with relevant international standards and as per customer specifications.

Alumina Gel

Some of the important uses of Alumina Gel are in the manufacture of Catalysts, Pharmaceuticals, Rubber, Cosmetic and Paper Industries.

Silica Gel

Synthetic Amorphous Silicon Dioxide(SiO2)-Sorbent/Sorbead Silica for industrial use are supplied to meet customer's requirements. It is a hard granular desiccant with the appearance of crushed glass. It is slightly softer than ordinary window glass, odorless, insoluble and nonconductor of electricity. Its action in adsorbing moisture is purely physical and there is no change in size or shape of the particle as it adsorbs vapour. Silica Gel has a very strong affinity for water, which give it an adsorption capacity of over 40% of its own weight at 100% relative humidity.

Its major application is moisture adsorption from air/gas streams and from organic liquid such as ethanol, benzene, etc. It is also used for preferential chemical adsorption to remove polar contaminates from non polar solvents-e.g., butanol from butyl chloride. Indicator Silica Gel is used where visual indication is required to show the need for regeneration. Granular and beaded, indicating and non indicating silica gel,etc, are supplied by us exactly to customers specifications.

Gamma Alumina Catalyst Carriers

Activated Alumina Catalyst Carriers are required to have excellent purity and adequate mechanical strength in order to facilitate proper impregnation of active ingredients. Additionally, a very high adsorptive capacity and high surface area make it suitable for Nox removal and other toxic vapors removal catalysts. Thus, it has substantial use in industrial pollution properties.

High Purity Alumina Carriers in the form of rings, spheres and tablets are used in different catalyst manufacturing processes. Our group produces them suitable for all purposes based on requests.

Ceramic Grinding Media

Petrogas expertise in technical ceramics has been proved in a wide variety of applications and industries including users of ball mills . Ceramic materials are hard, corrosion resistant, chemically inert, non toxic, non magnetic and non porous. These characteristics are well utilised for Mill Linings and Grinding Media for Ball Mills. We produce sintered alumina or Ceramic Linings & Grinding Media for use in many dry and Wet Grinding process.

Activated Alumina

Activated Alumina is a higly porous form of Aluminium Oxide with enhanced surface area. It is used for the adsorption of liquids and gases . One major application of Activated Alumina is as desiccant , either for the removal of bulk quantities of water or for drying of gases containing low concentration of water. The substances that can be treated with Activated Alumina are :Air, Ammonia, Argon,Carbon Dioxide, Furnace Gas, Hydrocarbon, Hydrogen, Nitrogen, Oxygen, Hydrogen Sulphide, Benzene, Gasoline, Lubricating Oil,Naptha, Vegetable oil, Kerosene, etc.

Claus Catalysts

The Clause process is used by the Sulfur Recovery Industry which converts Hydrogen Sulfide into elemental Sulfur and water. The "sour" natural gases have plenty of hydrogen sulfide within and if such gases are burned as fuel, Sulfide escapes, resulting in air pollution and damage to our tender enviornment. It has become an inevitable demand of mankind to convert maximum quantity of Sulfur from "sour" gas.

Activated Alumina is the most widely used Claus Catalyst which contains a large number of catalytically active surface sites that absorbs Hydrogen Sulfide (H2S) and Sulfur Dioxide (SO2) for subsequent reaction to yield elemental Sulfur.

In many acid gas streams, Sulfur is present in various compounds such as H2S, COS, CS2 etc. Some of them may not be present in the feed gas but cumbustion of H2S in the presence of CO2 or hydrocarbons could result the formation of COS/CS2. These compounds must be converted to ensure proper Sulfur conversion. Since the decomposition rate of these compounds are at lower rate than that of H2S/SO2 reaction, a highly active catalyst is required. Sulfation can be another problem as it reduces surface area and hence the deactivation of catalyst.

Molecular Sieves

PGMS Series Molecular Sieves are highly efficient adsorbents, mainly used to adsorb water, Methanol, Ethanol, Sulfated Hydrogen, Carbon Dioxide, Ethylene, Propylene, LPG etc. It is used as desiccant in industries for deep drying of air, natural gas and refigerant.
