International Classification:

F01N 3/36

US Classification:

60286, 60295, 60301

Abstract:

A method is provided for operating a diesel engine with reduced emissions. The method comprises combusting a first biodiesel blend fuel in a diesel engine resulting in the production of diesel exhaust gases containing NOx. The diesel exhaust gases are admixed with a second biodiesel blend fuel, and the second biodiesel blend fuel is hydrolyzed to form reducing agents. The diesel exhaust gases containing NOx are passed through an NOx-reducing catalyst to reduce the NOx through a selective catalytic reduction reaction with the reducing agents. The invention further provides a method for operating a diesel engine with reduced emissions, comprising combusting a first biodiesel blend fuel in a diesel engine resulting in the production of diesel exhaust gases containing NOx. A second biodiesel blend fuel is converted in a fuel processor thereby forming reducing agents, and the diesel exhaust gases are admixed with the reducing agents. The diesel exhaust gases containing NOx are passed through an NOx-reducing catalyst to reduce the NOx through a selective catalytic reduction reaction with the reducing agents.

Abstract:

The present invention details a process for producing a catalyst powder. The steps of the process include preparing catalyst slurry, drying, pyrolyzing, and calcining the catalyst slurry to obtain a calcined catalyst powder. The catalyst slurry comprises a catalyst, a liquid carrier, a templating agent, and a catalyst substrate. The catalyst slurry is dried to obtain a raw catalyst powder. The raw catalyst powder is heated in a first controlled atmosphere to obtain a pyrolyzed catalyst powder and the pyrolyzed catalyst powder is calcined in a second controlled atmosphere to obtain a calcined catalyst powder. A method of fabricating a catalyst surface and catalytic converter using the prepared catalyst powder is also illustrated.
