Effect of Hydrogen Addition on Noncatalytic Partial Oxidation of Natural Gas with Oxygen in a Flow Reactor with Increased Calorific Intensity

Abstract

The effect of hydrogen addition on the partial oxidation of a natural gas/O2 mixture was studied in a flow reactor with increased calorific intensity. The addition of hydrogen (CH4/H2 = 3) to a fuel-rich natural gas/O2 mixture with the oxidizer excess ratio α = 0.34 leads to an increase in the yields of H2 and CO and in the H2/CO ratio and to a decrease in the yields of CO2, H2O, C2H4, and C2H2 and in ∆C. The hydrogen addition at CH4/H2 = 3 positively influences the hydrogen production in partial oxidation of natural gas/O2 mixtures.
