Effect of the Calorific Intensity of Combustion Chamber on Production of Synthesis Gas in Partial Oxidation of Methane–Oxygen Mixtures in the Combustion Mode

Resumo

Optimal design of a flow-through chemical reactor with increased calorific intensity was experimentally sought for in partial oxidation of natural gas by oxygen at oxidant excess factors in the range 0.27 < α < 0.4. It was shown that this reactor with a chamber for additional turbulent mixing of the starting components, turbulizer, and supercritical pressure difference at the outlet from the combustion chamber can provide a combustion mode close to the process in the plug-flow reactor. The increase in the calorific intensity of the combustion chamber of the reactor as a result of a decrease in its volume leads to full conversion of the starting reagents and to lower carbon-black formation.
