The heat flux method burner shown in

A few recent high pressure experimental studies [2], [3], [4], [5], [6], [7] and [8] for SL have been reported in the literature for syngas (H2/CO/N2) mixtures. Most of these studies have not addressed high hydrogen content syngas with a lean mixture at elevated pressure. Much of the focus remains on stoichiometric and rich mixtures of such fuels. Lean mixtures have become important in recent applications such as mentioned above. Table 1 outlines the experimental studies reported in the literature for SL measurement at elevated pressures. It is apparent that SB 2343 high pressure studies of lean mixtures of H2/CO/N2 are scarce. In the present study, our focus remains on experimentally determining SL for validation of recent kinetic schemes. Hence, the objectives of Casparian strip study are to (1) experimentally determine SL of 85% H2 content in both H2–CO and H2–N2 mixtures at lean conditions (?? = 0.5–0.6) up to a pressure of 10 atm using the heat flux method in a new specially designed high pressure facility, (2) comparing recent kinetic models from Li et al. [9], Kéromnès et al. [6], Goswami et al. [8], Burke et al. [10] and GRI Mech 3.0 [11], and (3) analyzing the key reactions and pathways in the kinetics of such lean mixtures at elevated pressure.
