Full Record
Other Related Research

Abstract

A fuel injection and mixing system is provided that is suitable for use with various types of fuel reformers. Preferably, the system includes a piezoelectric injector for delivering atomized fuel, a gas swirler, such as a steam swirler and/or an air swirler, a mixing chamber and a flow mixing device. The system utilizes ultrasonic vibrations to achieve fuel atomization. The fuel injection and mixing system can be used with a variety of fuel reformers and fuel cells, such as SOFC fuel cells.

Catalysts having catalytic material applied directly to thermally-grown alumina and catalytic methods using same; improved methods of oxidative dehydrogenation

Patent Long, Richard; Watson, Junko M.; Daly, Francis P.; ...

The invention describes catalysts, methods of making catalysts, methods of making a microchannel reactor, and methods of conducting chemical reactions. It has been discovered that superior performance can be obtained from a catalyst formed by directly depositing a catalytic material onto a (low surface area) thermally-grown alumina layer. Improved methods of conducting oxidative dehydrogenations are also described.
