Abstract

Hydrogen rich gas produced in compact plasma reformers could be efficiently used for different mobile and stationary applications such as fuel cells, additives to lean burn gasoline engines and emission control. A compact plasma reformer is necessary to provide suitable fuel gas to the fuel cell for auxiliary power units (APU) of long distance trucks. Long distance truck runs typically include rest periods of between 6-8 hours per day. Fuel cells offer a high-efficiency, low emission, and low-noise alternative that would supplant the need for truck engine idle. A new type of plasma reformer developed for this purpose will be presented. Developing a diesel vehicle that meets the new emissions standards will require more than a 90% reduction in NO x over the next few years. A compact plasma reformer producing hydrogen rich gas could be used in a diesel exhaust aftertreatment process, HC- SCR (selective catalytic reduction), that includes NO x reduction by a mixture of hydrogen and hydrocarbons. The results of diesel engine tests using this technology will be discussed. The use of hydrogen rich gas as NO x reduction agent leads to significant (>50%) increase in NO x reduction efficiency compared to HC-SCR based on raw diesel fuel.
