Catalytic converter for confined areas

A catalytic converter for installation with a confined area, the confined area comprising a fixed, stationary structure containing exhaust gases from motor vehicle operations therein, the catalytic converter comprising:

• a housing having a substantially closed first end, an outlet end opposite the first end, and a plurality of inlet passages disposed between the first end and the outlet end, the inlet passages communicating with the confined area, the housing being adapted for installation within the confined area;
• a reservoir containing urea in aqueous solution;
• a pump connected between the reservoir and the first end of the housing, the pump being configured for pumping the urea solution through the housing;
• a plurality of catalytic converter elements disposed within the housing, the catalytic converter elements having a coating of a precious metal selected from the group consisting of platinum, palladium, and rhodium;
• and
• at least one electric heating element disposed within the housing, the heating element being configured for maintaining a temperature between 200° and 300° C. within the housing;
• wherein the catalytic converter is adapted for selective catalytic reduction of nitrogen oxides and hydrocarbon pollutants in vehicle exhaust emissions entering the housing through the inlet passages.
