Methods of producing hydrogen and nitrogen using a feedstock gas reactor

A method of producing hydrogen and nitrogen using a feedstock gas reactor comprising a reaction chamber fluidly connected to a combustion chamber via one or more fluid flow paths, the method comprising:

• introducing a feedstock gas comprising a hydrocarbon into the reaction chamber;
• introducing a combustible gas mixture into the combustion chamber, wherein the combustible gas mixture comprises air and one or more combustible gases;
• combusting the combustible gas mixture in the combustion chamber so as to form one or more combustion product gases comprising nitrogen and so as to cause at least a portion of the one or more combustion product gases to flow into the reaction chamber via the one or more fluid flow paths and mix with the feedstock gas, wherein, as a result of the mixing of the at least a portion of the one or more combustion product gases with the feedstock gas, energy is transferred from the at least a portion of the one or more combustion product gases to the feedstock gas and thereby causes a chemical reaction to decompose the feedstock gas into one or more reaction product gases comprising hydrogen;
• extracting a mixed product stream from the feedstock gas reactor, wherein the mixed product stream comprises hydrogen from the one or more reaction product gases and nitrogen from the one or more combustion product gases;
• collecting, from the mixed product stream, a ratio of hydrogen to nitrogen;
• and
• controlling the ratio of collected hydrogen to collected nitrogen by adjusting one or more parameters of the method.
