Catalysts & Catalyst Carriers

We supply high-purity fine cesium chemicals which are used as a small, but critical component in the manufacture of a variety of catalysts. We also offer activated carbons for phosgene production and destruction, precious metals catalyst carriers and cyanuric chloride.

Fine cesium chemicals

The unique properties of fine cesium chemicals enable you to improve process and product performance while reducing emissions. Fine cesium chemicals are used as dopants in vanadium catalysts, which are used in the production of sulfuric acid (H2SO4). Not all vanadium catalysts use cesium, but the addition of cesium salts to the conventional alkali-vanadium sulfuric acid catalyst formulations brings four distinct advantages to the catalyst user (sulfuric acid producers):

  • Cesium activates the catalyst at lower temperatures, resulting in reduced energy costs 
  • Significant increase in sulfuric acid production rate 
  • Up to 60% decrease in sulfur dioxide (SO2) emissions 
  • Greater operational flexibility to enable operators to optimize conditions to provide required acid production within acceptable SO2 emissions

The use of fine cesium chemicals can bring similar benefits to other catalysts, including for the production of methyl methacrylate (MMA), ethylene oxide and polyol, as well as in custom catalysts for specialist applications.

Activated carbon

Most chemical processes require a catalyst, making them of vital importance in the chemical industry. Industrial growth coupled with increasing fuel and environmental regulations, and more efficient use of raw materials continue to drive catalyst demand for chemical reactions. In comparison to other carriers, like silica or alumina, our activated carbons provide:

  • Greater internal surface area and lowest cost per cubic meter
  • Stable inertness in harsh process conditions such as acidic and alkaline solutions
  • Easy recovery of precious metals
  • No interference with selectivity or activity
  • No allowance of mixed compounds
  • Availability in powdered, granular and formed (extruded) shapes

Activated carbon can be used in various applications, such as:

Phosgene production 
  • Low pressure drop
  • High hardness
  • Prevention of fine dust generation and fouling of the equipment downstream, leading to high conversion and high yield
Phosgene destruction
  • Extraction of hydrochloric acid and carbon dioxide
  • Extreme high hardness for low dust generation 
  • Long catalyst lifetime minimizes exchange frequency
Precious metals catalyst carrier
  • Large pore volume and optimal pore volume distribution enables adsorption of unwanted by-products 
  • Internal surface provides an excellent base for the finely distributed catalyst compounds of metals and provides a high surface area for catalytic reactions
  • Macro pores increase the transport of reactants to and from the catalytic surface
  • Easy recovery of metals by burning the carbon
Cyanuric chloride
  • Promotes chlorination of hydrocyanic acid to cyanogen chloride and then to cyanuric chloride
  • High process yield
  • Improved abrasion resistance
  • High end product purity
