The Catalytic Performance of Ni/CeO2 Catalysts for WGS Reaction in a Microchannel Reactor

In order to research water-gas shift reaction (WGS) efficiency over nickel-ceria catalysts, a multidisciplinary integrative strategy was adopted that combines realistic experimentation and mathematical modeling, material science and chemical engineering. In various laboratory-scale reactor systems, such as fixed-bed and microchannel reactors, experimental studies have been conducted on the kinetic effects of metal fractions. The quasi-steady state kinetics were tested using a very dilute gas (1% CO + 1.8% H2O in Не) for the water-gas change reaction between 250 and 550 ° C. Using computational models, experimental findings were interpreted, and regression analysis determined kinetic parameters, while mechanistic aspects were considered only briefly. For the WGS reaction in the microchannel reactor, a series of experiments with practical feed gas having a composition similar to product gas from methane partial oxidation (CO:H2O:H2:N2 = 1:2:2:2) was performed.
