Abstract

Hydrogen production from partial oxidation of methanol (POM) under sprays and dual-bed catalysts are investigated. Two different catalysts of h-BN-Pt/Al2O3 and h-BN-Pd/Al2O3 with low Pt and Pd contents (0.2 wt%) are utilized, and the influence of the O2-to-methanol molar (O2/C) ratio on POM is also examined. It is found that POM can be triggered in cold start using the h-BN-Pt/Al2O3, whereas the h-BN-Pd/Al2O3 needs to be preheated to drive POM. The h-BN-Pt/Al2O3 is employed to displace the preheating system and combined h-BN-Pd/Al2O3 as dual-bed catalysts. Preheating temperature is not able to be concerned about the reaction obviously. The h-BN-Pt/Al2O3 was placed as the first layer to provide heat for the Pd layer. The maximum H2 yield is always located at O2/C=0.6, which stands for the transition point of the chemical reaction dominated by partial oxidation to combustion. Once the O2/C ratio is as high as 0.7, almost all methanol is consumed in dual-bed catalysts. Overall, POM can be triggered by preheated h-BN-Pd/Al2O3 and dual-bed catalyst with h-BN-Pt/Al2O3 to produce hydrogen.
