Abstract: front page image
(EN)

A novel catalytic reactor is provided for controlling the contact of a limiting reactant with a catalyst surface. A first flow vessel defines an interior surface and an exterior surface, and the interior surface has a catalyst deposited on at least a portion thereof. A second flow vessel is positioned within the first flow vessel and the second flow vessel defines a porous surface designed to deliver a fluid uniformly to at least a portion of the interior surface of the first flow vessel.
