摘要: The presence of significant concentrations CO2 with methane, especially for very lean mixtures in air affects adversely the unanalyzed combustion processes such fuels common conventional devices. catalytic oxidation homogeneous CH4-CO2-air on a non-adiabatic lab-scale Pt/Al2O3 packed bed reactor was investigated numerically. model employed two-phase treatment volume averaging while accounting effects mass and heat transfers between solid gas phases. All three modes transfer as well detailed surface chemical kinetics were incorporated. applied to simulate fuel at atmospheric pressure within that fed preheated fuel-air mixtures. changes value inlet feed temperature (600 Tinlet 900 K), equivalence ratio (0.15--0.55), composition (0%--90% CO2) investigated. Based simulation results, methane ra...
