A gas generator which comprises a heat resistant housing and a reaction chamber which is centrally arranged therein and contains a catalytic charge, with an inlet opening for the reactants and an outlet opening for the fuel gas is used for catalytically reacting liquid, hydrocarbon containing fuel to be evaporated with an oxygen containing gas at elevated temperature to form a fuel gas. The housing consists of a lower part and a removable cover and the reaction chamber including the catalytic charge is replaceable. The fuel and/or the oxygen containing gas is fed to the reaction chamber for preheating and evaporating, respectively, via a system of tubes which is arranged between the reaction chamber and the lower part of the housing and is run around the reaction chamber in helical fashion.

Gas generator for catalytically reacting liquid, hydrocarbon containing

In a gas generation method in which liquid fuel is catalytically reacted with air at elevated temperatures to form a fuel gas, several plates each having a multiplicity of passage openings are arranged in tandem in spaced fashion within the reaction chamber of the gas generator and are embedded in a bed of packing material with the thermal conductivity of the plates higher than that of the packing material in order to obtain more uniform heating of the reaction chamber and better mixing and distribution of the reacting media permitting the gas generator to be loaded more heavily.

Method for converting a reaction mixture consisting of

A starting device for reformed gas generators of the type in which atomized or evaporated liquid, hydrocarbon containing fuel is catalytically reacted with a gas containing oxygen at elevated temperatures to form a fuel gas, includes a conically shaped housing having an outlet for coupling to the inlet of the reformed gas generator, a gas permeable burner plate within said housing, a fuel injection nozzle arranged so that nearly the entire surface of the burner plate is supplied with fuel, a heat-resistant, gas permeable terminating plate filling, the outlet of the starting device and defining, with the burner plate, a combustion chamber, an ignition device disposed in said combustion chamber and means for introducing the air and atomized fuel into the combustion chamber through the burner plate.

Starting device for a reformed gas generator

According to the invention, the fuel is supplied to the reformed-gas generator in an amount at least approximately proportional to the instantaneous demand of the internal-combustion engine and is mixed there, in atomized or evaporated form, with so much air and/or fed-back exhaust gas drawn in through the reformed-gas generator that for the air component of the mixture, the air number for the reaction of the fuel in the converter is at least 0.05 but not more than 0.5 and the exhaust gas component does not fall below the exhaust gas quantity equivalent to the air number 0.05 and does not exceed the exhaust gas quantity equivalent to the air number 0.5. The fuel gas mixture produced in this manner, prior to being fed to the combustion chambers of the internal-combustion engine, is mixed with enough additional air sucked in by the internal-combustion engine such that the air number for the combustion in these combustion chambers is at least equal to 1.

Method and apparatus for operating an internal combustion engine

A fuel gas obtained in a reformed gas generator through the catalytic reaction of hydrocarbons and a gas containing oxygen and provided to an internal combustion engine has its heat content along with that of the exhaust gas of the engine used to convert methonal endothermically into a gas mixture containing carbon monoxide and hydrogen with the gas mixture so formed fed to one or both the reformed gas generator and, along with the fuel gas, the internal combustion engine.
