Proceso y sistema para producir un gas que comprende nitrógeno (n2) e hidrógeno (h2) por combustión de hidrógeno en presencia de aire

La presente invención se relaciona con un proceso y sistema para producir un gas que comprende nitrógeno (n2) e hidrógeno (h2) por combustión de hidrógeno en presencia de aire. The technology relates to a process and system for producing a gas comprising nitrogen (N2) and hydrogen (H2) in a reaction chamber of length L of a reactor. The process comprises injecting air and injecting hydrogen into the reactor and the combustion of a portion of the injected hydrogen with the oxygen from the air in the reaction chamber, in the presence of an overstoichiometric molar excess of hydrogen relative to the oxygen from the air. The combustion is supported by a flame produced by an air flow having a velocity v1 resulting from the injection of air, surrounded by a hydrogen flow having a velocity v2 resulting from the injection of hydrogen, with the velocity v2 being greater than v1.
