摘要： 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.

摘要： The technology relates to a method of producing synthesis gas comprising carbon monoxide (CO) and hydrogen (H2), wherein the synthesis gas is produced by a reduction reaction of a first flow comprising a carbon source and an excess of hydrogen in contact with an Oxy-flame. The hydrogen comes from a reducing stream, a first portion of which ends up in the first flow, and a second part of which is used to generate the Oxy-flame by combustion of the hydrogen in the presence of a second flow comprising oxygen (O2), the second flow coming from an oxidizing stream. The first flow and the second flow are at a distance from each other such that the Oxy-flame supports the reaction between the carbon source and the hydrogen. A reactor, which can have different configurations, is also proposed for implementing the method.
