Engelhard Precious Metals Technology means better yields-

from Acetaldehyde to Zingerone! Engelhard catalysts—utilizing platinum, palladi­um, rhodium, ruthenium and osmium—are essential to many of the newer, more efficient processes for producing nitric acid, hydrogen cyanide, hydrogen peroxide and a host of other chemical intermediates.

Engelhard technology reduces costs and improves yields. In our proprietary nitric acid process, for example, the precious metal content in the catalyst is reduced by 50%. Ammonia pro­duction is increased 3-5%—from the same vol­ume of natural gas feedstock—with Engelhard's Selectoxo'R catalyst process.

Engelhard's Deoxo® catalysts remove oxygen, hydrogen and other impurities from industrial

gases. Others abate odors, organic vapors, carbon monoxide and nitrogen oxides from chemical, food and sewage treatment plants. Our inert gas purification and recycling systems recover inert gases for recycling, and even purify engine exhaust and boiler stack gas into non-corrosive inert gas to replace natural gas in oil well pressure maintenance and secondary oil recovery operations.

And millions of dollars' worth of precious metals are recovered every year by Engelhard's refinery from plant waste, scrap and spent catalysts.
