Abstract

Abstract A method of methyl alcohol treatment and distribution for an automobile internal combustion engine including the sequence of steps as follows: (a) heating a catalyst bed reactor to a start-up temperature using exhaust gas from an internal combustion engine being operated on atomized methyl alcohol; the catalyst bed reactor including a partial combustion catalyst and a methanol dissociation catalyst; (b) isolating the catalyst bed reactor from the exhaust; (c) vaporizing liquid methyl alcohol to form alcohol vapor; (d) mixing the alcohol vapor with air in a constant ratio of oxygen to alcohol at variable alcohol flow rates, to form a partial combustion mixture; (e) contacting the partial combustion mixture and the partial combustion catalyst to exothermically form dissociation mixtures the dissociation mixture including methanol vapor, water vapor, carbon monoxide, and hydrogen each in substantial proportion; (f) contacting the dissociation mixture and the dissociation catalyst to endothermically form hydrogen-rich fuel the hydrogen-rich fuel including hydrogen and carbon monoxide each in substantial proportion, the hydrogen rich fuel being formed from the alcohol vapor substantially adiabatically; (g) mixing air and the hydrogen-rich fuel to form a total combustion mixture; (h) burning the total combustion mixture in an internal combustion engine.
