Abstract
An integrated micro-ceramic chemical plant having a unitary ceramic body formed from multiple ceramic layers in the "green" state which are sintered together includes the unitary ceramic body defining a receiving chamber which includes a reaction chamber position and having first and second passages for providing communication with the reaction chamber position so that two or more fluids may be delivered to such reaction chamber position for reaction; the unitary ceramic body defining a receiving chamber which includes the reaction chamber position. The integrated micro-ceramic chemical plant further includes a movable member insertable into the receiving chamber and defining a plurality of separate catalytic reaction chambers and micro-filtering chambers, each such catalytic reaction chamber being provided by a micro-porous ceramic member which includes a catalyst impregnated into the micro-porous ceramic member. The movable member is moved to the reaction chamber to position a selected micro-filter chamber or micro-ceramic catalytic reaction chamber in communication with the first and second passages.
