Heterogeneous Catalysts

Heterogeneous catalysts are extensively used in chemical industries because of their activity, selectivity and recycle capability. Industrial catalytic processes are highly cost effective as it is as it involves moderate reaction conditions, high yields, high throughputs, minimal by-products and process costs, which make the industrial process highly cost effective.

These catalysts mainly find applications in liquid phase hydrogenation, dehydrogenation, and oxidation reactions usually in stirred tank reactors. This requires finely divided material which can be easily suspended within the reaction medium.

Finely divided platinum group metal salts are supported on a high surface area material, with various loading, under extremely controlled conditions. It involves careful selection of various parameters such as a metal precursor, its concentration, pH, temperature, precipitating agent, reducing agent, sequence and rate of addition of various salts to make efficient catalysts.

The surface area of the support determines metal loading and dispersion. The pore size distribution influences the diffusion rates and controls the course of the reaction. Surface chemistry, and thermal and chemical stability of the support decides the performance of the catalyst. The metal location, its crystallite size and oxidation state influences a catalyst's selectivity. The support also facilitates improved metal recovery.

There are diverse advantages of tailored-catalyst that include strong technical assistance, capacity enhancement in short duration, higher metal return, shorter delivery time and world-class production facilities.

Homogeneous Catalysts

Precious Metal Compounds

Homogeneous catalysts are precious metal compounds/salts which are usually associated with organic ligands. These homogeneous catalysts offer a great advantage for chemical reaction in terms of mild reaction parameters with high activity, and selectivity such as chemoselectivity, regioselectivity, steroselectivity, enantioselectivity and recyclability. In contrast to a heterogeneous catalyst, a homogeneous catalyst and reactant are in the same phase during the entire duration of reaction, thus eliminating pore diffusion limitation on an industrial scale. As the homogeneous catalyst mechanism is better understood, manipulation of process parameter becomes easier. PGM metal homogeneous catalysts are crucial in homogeneous catalyst reactions.

The drawback of a homogeneous catalyst is difficulty in separation and recovery of catalyst. A small loss of homogeneous catalyst leads to a huge financial burden, elongated chemical process and contamination of environment making it an uneconomic process. Hindustan Platinum leads the way by providing a complete loop for recovery of PGM from spent homogeneous catalysts.

Suitable Supports

For powder precious metals catalysts, the support has an active role to play. The surface area and hydroxyl groups present of the support determines metal loading and dispersion. The pore size distribution influences the diffusion rates and controls the course of the reaction. Surface chemistry and thermal and chemical stability of the support determines the catalyst’s performance. The metal location on the support, its crystallite size and oxidation state influences the catalyst’s selectivity.

Activated Carbon

Alumina

Other Supports

Mostly derived from natural sources, this commonly used support is subjected to physical and chemical variations. Its surface area can range up to 1200 m2/g. The carbon supported catalyst comes as dry powder or a paste with 50% water. The former is considered potentially more pyrophoric in the presence of organic solvents and needs more skillful handling. Furthermore, handling losses are minimized by using the wet catalyst. At times the catalyst can be reused like washing with water followed by solvents. Easy recovery of precious metals can be possible by carbon incineration.

This support with a surface area of up to 300 m²/g can be produced in pure state. Apart from the surface area and porosity, other performance related parameters can be adjusted to the desired catalytic process. This well characterized support has low absorption, high thermal stability than carbon and is non-combustible.

Calcium Carbonate, Barium Carbonate and Barium Sulphate are low surface area supports with low absorptive capacity which are used for specific catalyst manufacturing.

We create excellence in the business

1. Metal Recovery & Refining

The homogenized material goes through several physical and chemical processes for optimum recovery of the precious metals. These metals then undergo refining, the final purification process, which yields precious metals of purity above 99.95%, meeting international standards.

2. HOMOGENIZING & SAMPLING

Sampling is the crux for accurate determination of precious metal content in scrap material. This material needs to be homogenized to draw samples which represent the entire lot. Depending on the nature of the material, this can be achieved by a combination of incineration, sieving, grinding, blending & melting. Multiple representative samples are then drawn for evaluation of metal content by us, by the customer & if required by a reputed international laboratory.

3. METAL ANALYSIS & EVALUATION

Different analytical methods are employed to determine the concentration of precious metals in the homogenized sample which range from ppm level to 99.99% metal content. In addition to the traditional wet-chemical and fire assay methods, Hindustan Platinum uses advanced methods such as absorption and emission spectroscopy to reveal the exact content of precious metals. The choice of analytical methods is judiciously made depending on the type of material. Apart from this, the impurity profile is also determined for any purified metals for the manufacturing of high quality finished products. Analytical reports determining precious metals content are presented to the customer for approval & final settlement.

4. MANUFACTURED PRODUCTS

High purity precious metals are used to manufacture a wide array of sophisticated industrial products. All our supplies are accompanied by our Certificate of Analysis (CoA). The entire cycle of precious metal recovery is conducted through environment friendly processes which deliver high-yield, high-purity final products within the committed time.

5. CATALYST MANUFACTURING

Precious metal catalysts hold a unique position because of their high catalytic performance (activity, selectivity, filterability and recyclability). Hindustan Platinum has perfected the art and science of manufacturing homogenous and heterogenous catalysts for different industrial applications. For more than four decades, Hindustan Platinum has been serving the industry and has earned itself an enviable reputation and stature in the field of precious metal catalysts. The manufacture of precious metal catalysts involves complex procedures and processes which require strict adherence to material and process quality parameters. Every ingredient used in the development of the catalyst is sourced from approved manufacturers/vendors and analysed internally for its quality.
