Catalysts containing 30 weight percent or more platinum have surprisingly been discovered to possess superior stability and activity for catalyzing combustion reactions. The addition of rhenium improves catalyst performance in fuel lean conditions but has undesirable effects in fuel rich conditions.

Catalysts containing 30 weight percent or more platinum have surprisingly been discovered to possess superior stability and activity for catalyzing combustion reactions. The addition of rhenium improves catalyst performance in fuel lean conditions but has undesirable effects in fuel rich conditions. The invention provides integrated combustion microreactors, chemical systems utilizing these integrated combustion microreactors, methods of combustion, and methods of providing heat to endothermic reactions in integrated combustion microreactors.
