Optimization of hydrogen production by filtration combustion of natural gas by water addition

Abstract

The effect of adding steam during filtration combustion of natural gas air mixtures was studied with the aim to evaluate the optimization of hydrogen production. Temperature, velocity, chemical products of combustion waves, and conversion from fuel to H-2 and CO were evaluated in the range of equivalence ratio (9) from stoichiometric (phi = 1.0) to phi = 3.0 and steam content in the mixture from 0% to 39%, at filtration velocities from 12 to 25 cm/s. Numerical simulation was carried out using GRI-MECH 3.0. Results suggest that H-2 and CO concentrations, dominant for rich and ultrarich combustion, are products from partial oxidation and steam natural gas reforming processes. Experimental and numerical results show that hydrogen yield increase with an increase of steam content in the natural gas air mixtures. Copyright (C) 2014, Hydrogen Energy Publications, LLC.
