Summary of PGM Metal Catalysts

• Selective hydrogenation

– Acetylene conversion to ethylene

– pyrolysis gasoline

– Poly alpha olefins (PAO’s)

– Paraffins for LAB production

– General in the presence of other functional

groups

– Methyl Acetylene Propadiene (MAPD)

– C4’s and C5’s

• Nitrobenzene to aniline

• Hydroformylation Catalyst

• Alpha methyl styrene hydrogenation to cumene

• Hydrosilation for silicones production

• Phenol

• Dehydrogenation of cyclohexanone

• Hydrogen Peroxide (via anthroquinone route)

• Antioxidants/UV Stabilizers

• Methanation (with PGM catalyst)

VULCAN Series PGM Catalyst features

High Activity

For faster reaction rate, low catalyst loading & shorter reaction time to maximize production throughput.

High Selectivity

To maximize the yield, eliminate by-products and reduce purification costs.

High recycle capability

To minimize process costs

Optimized catalyst support

• Strength – Reduces dP to acceptable levels, maintaining throughput

• Pore structure – Key to enabling rapid reactant diffusion

• Surface area – must be adequate for active metal impregnation

• pH controlled – can impact on selectivity and

• Thermal stability – high temperature operation may be required

• Inert – should not react with the solvent, feedstock or reaction products
