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.

Method and apparatus for the catalytic conversion of the exhaust

Accelerated reaction rates and improved yields are accomplished when sulfides of metals of groups Ib, IIb, IVa, Va and VIII of the Periodic Table are oxidized in aqueous medium to convert the sulfide sulfur to elemental sulfur by performing the reaction in the presence of activated carbon.
