Abstract

The aim of this study is to perform autothermal reforming (ATR) of methanol by sprays via the h-BN Pt catalyst with cold start for the hydrogen production. The present works mainly focus on the effects of operating conditions on hydrogen production and methanol conversion. Meanwhile, the comparison between ATR and partial oxidation of methanol (POM) are also carried out. The results of POM indicate that the highest H2 and CO concentrations are obtained at O2/C (molar ratio of air and methanol) = 0.7, and the CH3OH conversion can reach 100%. In the ATR process, the methanol conversion reaches 60% under O2/C ratio =0.7 with S/C (molar ratio of steam and methanol) = 1.5. At S/C =0.5, the CH3OH conversion increases with increasing the O2/C ratio and is up to 100%, and the H2 yield is higher than that of POM. The highest H2 yield from ATR is 1.697 mol (mol CH3OH)-1 occurs at S/C =0.5 and O2/C=0.7.
