Analysis of an idealized counter-current microchannel-based reactor to produce hydrogen-rich syngas from methanol

Abstract

h i g h l i g h t sWe present a numerical model for portable hydrogen production for fuel cells.Methanol thermal partial oxidation in counter-current channels is investigated.Maximum hydrogen yield of 60% at equivalence ratios between 3 and 6 is predicted.Gas inflow velocity has small influence on the conversion efficiency of the reactor.

Performance evaluation of methane‐fueled reactor for hydrogen production: Experimental permeability measurements and reactive flow modeling

“…Other researchers have conducted studies that explore the design aspect of reactors. In fact, optimizing the design of reactors mainly seeks to offer best hydrodynamic conditions, such as the optimization of inlet parameters, 15,16 the flow management within the reactors, 17,18 and the improvement of catalyst properties. Through an experimental study, Zhang et al 19 studied the SMR process, the effect of the Ni catalyst on the performance of micro-channel reactor.…”

Superadiabatic small-scale combustor with counter-flow heat exchange: Flame structure and limits to narrow-channel approximation

“…A viable solution for combustion of low-energy-containing mixtures might be the use of small-scale devices with heat exchanging between adjacent counter-flow streams. The idea of this sort of devices should be traced back to [7][8][9] and the corresponding studies have received significant attention over the past two decades [10][11][12][13][14][15][16][17][18][19].…”

“…Various numerical studies based on two-dimensional governing equations were carried out in [14][15][16][17] for different burner configurations. The influence of power extraction on combustion regimes has been reported recently in [18] and the production viability of hydrogen-rich syngas from methanol has been explored in [19].…”
