Precise catalyst particle design and control are key to optimizing process cost, speed and efficiency.

In heterogeneous catalysis, the catalyst and reactants exist in two different physical states, most commonly a solid catalyst in a liquid reaction mixture.  Catalysis occurs when the reactants adsorb onto the catalyst active sites, react on the catalyst surface and finally desorb, leaving the catalyst active sites available for another set of reactants.  Due to the surface reactivity mechanism of heterogeneous catalysis, particle design and control are key to optimizing process cost, speed and efficiency.

At Shepherd, we leverage decades of aqueous metal chemistry and precipitation experience to co-develop and manufacture:

• High purity, high concentration mixed metal solutions as heterogeneous catalyst precursors.
• Impregnated catalyst supports.
• Custom particles, fine tuned in size, surface area, and morphology, with potential to eliminate the need for catalyst supports.

Our technology can improve production costs and reduce waste streams for environmental, refinery and polymerization catalysts.
