Enhancement of Ni-NiO-CeO Interaction on Ni-CeO/AlO-MgO Catalyst by Ammonia Vapor Diffusion Impregnation for CO Reforming of CH.

Ni-based catalysts have been widely used for the CO reforming of methane (CRM) process, but deactivation is their main problem. This study created an alternative electronic Ni-NiO-CeO interaction on the surface of 5 wt% Ni-5 wt% CeO/AlO-MgO (5Ni5Ce(xh)/MA) catalysts to enhance catalytic potential simultaneously with coke resistance for the CRM process. The Ni-NiO-CeO network was developed on AlO-MgO through layered double hydroxide synthesis via our ammonia vapor diffusion impregnation method.

Combined Steam and CO Reforming of Methane over the Hierarchical Ni-ZrO Nanosheets/AlO Catalysts at Ultralow Temperature and under Low Steam.

This research developed hierarchical 10 wt % Ni-1 wt % ZrO/AlO catalysts for combined steam and CO reforming of methane (CSCRM) reaction to produce syngas for gas-to-liquid (GTL) application under the ultralow temperature and low steam condition. The hierarchical nanosheet catalysts were prepared via a novel impregnation technique assisted by ammonia vapor diffusion with various times (1, 6, and 12 h) to develop the different magnitude of hierarchical nanosheets on the surface. Then, CSCRM at 600 °C was performed on the catalysts for 6 h.
