Abstract

A micro catalytic combustor was studied as a heat source for micro scale endothermic reactor, which is made from inserting sintered Ni micro-fiber entrapped fine particulates Pt/Al₂O₃ catalyst in a millimetric scale reaction chamber. The catalytic combustion performance of H₂/Air under different experimental conditions and Pt loading has been investigated and the structure and properties of catalysts were characterized. The results showed that the normally highly explosive reaction of H₂/air could be conducted in this micro catalytic combustor with inherently safe operation, and over Pt loading would decrease catalytic combustion performance. At 83°C and 2.0 × 10⁵ h^-1 with 28.5mol% H₂ inlet concentration and 5wt% Pt loading, hydrogen conversion can still be over 92.2%.
