| Summary: | The current study aimed to improve dry reforming of methane (DRM) through forming catalyst as a thin film. To this end, the Ni catalyst was deposited on an Al2O3-ZrO2 support via physical vapor deposition, which is a technique for coating in vacuum. Using this technique, the catalyst was coated on stainless steel plates as the substrate in a microchannel reactor. Moreover, with the aim of increasing adhesion and reducing the thickness of catalytic particles, high levels of energy in short coating times were applied. Also, to examine the DRM, a mixture of feedstock gases, including methane, carbon dioxide, and helium were used with ratios of 1:1:8 as well as a flow rate of 10 mL/min, at various temperatures (ranging from 700-800 °C) and different coating times (ranging from 1- 4 min). The maximal performance was recorded for the coating time of 4 min and the operational temperature of 800 °C. As the flow rate of the inlet feedstock to the microchannel reactor declined and the gas hourly space velocity (GHSV) was equal to 33600 (mL g-1.h-1), the experimental equilibrium conversion rates of the CH4 and CO2 reactants were equal to 90.1 % and 94.6 %. |
