Catalytic metal additive concentrate and method of making and using

Abstract From the Canadian patent

Delivery of metallic combustion catalysts to internal combustion engines and other combustion devices is improved by dosing units that have the ability to effect the slow and positive supply of metallic additives including platinum , and/or cerium containing catalyst compositions to fuel. The invention , provides additive dosing materials and methods for simply and effectively supplying catalytic metal fuel additives to fuel in suitable low concentrations as are effective. The dosing units can be used with devices made to contact diesel fuel. In one approach a catalytic metal additive , concentrate (CMAC) is prepared in normally solid semisolid or viscous form. , The CMAC will …
