Cu/ZnO/Al2O3/Cr2O3/CeO2 Catalyst for Hydrogen Production by Oxidative Methanol Reforming via Washcoat Catalyst Preparation in Microchannel Reactor

Abstract

The oxidative methanol reforming reaction was carried out using Cu/ZnO/Al2O3/Cr2O3/CeO2 (15/15/2.5/1.25/1.25 mol%), with washcoat by EC sol on microchannel reactor. The experimental conditions were used various sol for washcoat of catalyst, various method for calcinations of catalyst, steam to methanol mole ratio, the mole ratio of oxygen to methanol, weight hourly space velocity, reaction temperature. The experiment result shows that methanol conversion achieved 98.8 % and carbon monoxide concentration equal to 1204 ppm when using Cu/ZnO/Al2O3/Cr2O3/CeO2 (15/15/2.5/1.25/1.25 mol%) catalyst mixed with EC sol at the reaction temperature of 200 o C.

Design, Fundamental Principles of Fabrication and Applications of Microreactors

“…Diminishing the microchannel permits facile modification of tentative circumstances on the order of microseconds, while the feedstock capacity can be significantly condensed to microliter scales [59,130,150]. The oxidative methanol reforming reaction has been carried out using Cu/ZnO/Al 2 O 3 /Cr 2 O 3 /CeO 2 with a wash coat by ethylene cellulose (EC) sol on a plate microchannel reactor, as shown in Figure 5a [183].…”
