TECHNICAL ABSTRACT (LIMIT 200 WORDS)
It is proposed to develop compact and lightweight ceramic heat exchangers and chemical reactors suitable for high temperature processes. These devices will have micro-scale geometric features that would result in very high heat and mass transfer rates per unit volume and per unit frontal area. The process for fabrication of these devices is based on a novel micro-machining and joining technique that promises to deliver ceramics components that can survive temperatures in excess of 1000 oC, and moderate to high pressures. As ceramics are the natural host for a large number of catalysts, the proposed devices would allow fabrication of extremely compact chemical reactors capable of operating at high temperatures. These devices can be used to thermally couple exothermic and endothermic reactions. Furthermore, temperature-sensitive reactive streams can be coupled to heat transfer streams to achieve temperature-controlled chemical reactions at high catalytic conversion and selectivity. Examples would include integrated catalytic combustor and heat exchanger, coupled catalytic combustion and steam reforming, and coupled Sabatier and Reverse Water Gas Shift reactions.

POTENTIAL NASA COMMERCIAL APPLICATIONS (LIMIT 100 WORDS)
The proposed high temperature ceramic micro-structured devices are suitable for a number of thermo-chemical energy conversion processes as well as Lunar and Mars in-situ resource extraction processes. A large number of these processes take place at high temperatures, well beyond the capabilities of metal-based micro-structured heat exchangers and chemical reactors.

POTENTIAL NON-NASA COMMERCIAL APPLICATIONS (LIMIT 100 WORDS)
The high performance per unit volume and mass of these devices are also of significant importance to commercial activities in high temperature gas turbine regenerators, fuel cells, and catalytic chemical production processes.
