Methods of producing hydrogen and nitrogen using a feedstock gas reactor

A system comprising:

• a feedstock gas reactor comprising:
• a reaction chamber;
• a combustion chamber fluidly connected to the reaction chamber via one or more fluid flow paths;
• and
• an igniter;
• valving for controlling flow of gases into and out of the feedstock gas reactor;
• and
• one or more controllers configured to perform a method comprising:
• controlling the valving to introduce a feedstock gas comprising a hydrocarbon into the reaction chamber;
• controlling the valving to introduce a combustible gas mixture into the combustion chamber, wherein the combustible gas mixture comprises air and one or more combustible gases;
• controlling the igniter to combust 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;
• controlling the valving to extract a mixed product stream from the feedstock reactor, wherein the mixed product stream comprises hydrogen and nitrogen;
• 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.
