CFD modeling of compact methanol reformer

摘要: Abstract The compact fuel processor that uses methanol as a feedstock for the production of hydrogen and temperature control was studied by computational fluid dynamics. integrates in single package methanol–water evaporator, gas flow distributors, steam reformer methanol–air catalytic combustor. combustor were formed tubular reactors possessed metallic body like monolith with an array circular cross-section through-holes. Part holes filled reforming catalyst other part oxidation methanol. design provides efficient heat transfer between reformer. distribution is almost uniform. value nonuniformity does not exceed ΔT = 2.4% any reaction zone. Maximum overall effectiveness achieved at feed equal 17.24 mmol/min (GHSV = 12,424 h−1) 8.75 mmol/min (GHSV = 16,632 h−1) combustor, respectively. Under these conditions performance to 70.0 l/h (48.7 mmol/min) 286.4 °C
