Abstract
Catalytic conversion of the exhaust discharge of internal combustion engines is accomplished by contacting the discharge with a naturally-occurring mineral chrysocolla, the structure of which provides a sufficiently large surface area without further support, the chrysocolla serving as an oxidizing catalyst and which can also be modified to serve as both an oxidation and reduction catalyst. The invention includes the catalytic converter device incorporating the catalyst.
