Catalysis

Catalysts are widely used in the chemical and petrochemical industry, but also in automotives, pharmaceuticals and modern biochemicals. Many chemical reactions are only viable due to the use of inorganic and organic catalysts. Catalysts overall are more than a $10 billion-per-year business. About 90% of the chemicals and more than 20% of the industrial products employ a catalytic step in the manufacturing process. Petroleum refining for example consists almost entirely of catalytic processes.

 

TREVER®|LYST polymeric catalysts are primarily using functionalized styrene divinly benzene copolymers, others to a lesser extent are acrylics and phenolics. Optimized porosities and surface properties allow an optimal usage of these catalysts.

TREVER®|LYST catalysts can be both, gel type or macroporous. They have been developed for the major reactions using polymeric catalysts such as alkylation, dimerization, etherification, esterification and hydration.

 

CHEMRA is open to further develop these catalysts for new reactions such as esterifying free fatty acids in biodiesel or in the production of natural detergent alcohols. Others are sorbitol esters and esters from organic acids.

 

Furthermore polymeric adsorbents have been developed which can be used as carriers for biocatalysts and metal complexes.

In some cases expensive metals can be recovered from either homogenous calalysis or in the catalyst recovery process.
