Catalyst Development
Environex develops catalysts designed to meet customers applications in a competitive manner.
Catalyst development services include
- selection of raw materials,
- material processing,
- catalyst formulation,
- washcoat adhesion, and
- catalyst aging studies.
We have experience in developing
- SCR catalysts,
- Diesel Oxidation Catalysts (DOC),
- Three-Way Catalysts (TWC),
- CO oxidation catalysts,and
- other reductive and oxidative catalysts.
Common catalyst applications include
- air pollution solutions,
- diesel emission control,
- industrial air pollution control,
- vehicle emission reduction,
- various zeolite applications for catalysis, and
- designing diesel oxidation catalysts for retrofit equipment.
We have experience in a variety of heterogeneous catalyst support types, support materials, oxygen storage materials and active materials.

Development
Environex provides unique insights into formulation and processing techniques. We can assist from lab-scale development to full-scale processing of catalyst products. We use wet and dry mills, shear mixers, and convection dryers for lab-scale formulations. Raw material and in-process characterization assist optimization of catalyst formulations. Coating optimization and adhesion studies and catalyst aging studies optimize the catalyst’s long-term success while minimizing costs.
