Title: Alcohol reforming apparatus
Inventor: HIROTA TOSHIO
IPC: F02M31/08
Filed: 1983-09-01
Abstract: PURPOSE:To make uniform the temp. in a reforming section in an apparatus for converting alcohol to H2-rich gas utilizing the heat of engine exhaust gas, to reduce fuel consumption and to stabilize the engine by supporting reforming catalyst on a perforated grid-shaped heat conducting member. CONSTITUTION:Alcohol vapor introduced from an inlet 12 and evaporated in an evaporating section 9 is fed to an inlet chamber 14a of a reforming apparatus through a passage represented by a chain line. The gas is then introduced into the reforming section 5 (7 is a catalyst supporting member, and 7a is a small hole, 6 is the catalyst) where it is reacted, and produced H2-rich gas is taken out through an outlet chamber 15a and an outlet 15 of the reformed gas. Since the above described reaction is an endothermic reaction, necessary heat is supplied utilizing the heat of engine exhaust gas introduced from an inlet 18 and exhausted from an outlet 19. In the above-described apparatus, the reforming section 5 is constructed by using grid-shaped heat conducting member 28 comprising perforated plates 29 having samller holes 30 and constructing the wall surface vertical to the direction of the flow of feed gas and supporting the catalyst 6 on the heat conducting member 28.
