the position of the deflector will determine the relative portions of the volume gas present at the inlet which are directed to each outlet in the embodiment shown approximately 75 percent of the gas at the inlet 77 of the gas splitter 79 is directed to hydrogen absorber 81 from outlet 82 of the gas splitter 79 while the remaining portion is directed from outlet 85 back to a combustion unit 86 which produces the hot combustion gases to heat the vessel 73 alternatively electrical heating coils may be used hydrogen absorber 81 may be identical to that described for the embodiment of fig1 above the gas output from hydrogen absorber 81 may be used in various applications in one variation the gas may be used directly as a motor fuel or in another variation may be applied to a methanator chamber which is a conventional commercially available apparatus to produce natural gas if it is desirable that the product gas be primarily hydrogen as would be the case for commercial hydrogen applications a water gas shift reactor 87 may be used the water gas shift reactor is a conventional device and comprises a reaction chamber referred to as a bottle which contains water vapor and a catalyst in operation the mixture of hydrogen and carbon monoxide gases from hydrogen absorber 81 are passed through the reaction chamber along with the water vapor the.
