Abstract: A fuel treatment and distribution apparatus for use with an internal combustion engine comprising an alcohol storage tank,a vaporizer,a catalyst containing reactor,a dissociated alcohol storage tank,and a by-pass conduit means,said alcohol storage tank being in fluid flow communication with said vaporizer means,said alcohol storage tank being in fluid flow communication with said by-pass conduit means,said vaporizer being in fluid flow communication with said catalyst containing reactor means,said catalyst containing reactor means being in fluid flow communication with said dissociated gas storage tank,said dissociated gas storage tank being in fluid flow communication and internal combustion engine said by-pass conduit means being in fluid flow communication with said internal combustion engine whereby peak operating capacity being handled by addition of liquid alcohol through said by-pass conduit.

Abstract: In a reactor consisting essentially of a monolithic substrate containing a plurality of substantially parallel channels having catalytic surfaces and means for charging a reactant stream into the channels and recovering a product stream from the channels, an improvement comprising; positioning a plurality of passageways through the monolithic substrate generally parallel to the channels with the passageways being adapted to pass a heat exchange fluid through the monolithic substrate.
