  Abstract

This study investigated synthesis gas production via steam reforming of biogas. Ni-Al2O3 and Ni-CeO2 catalysts were synthesized using the co-precipitation method, with controlled precipitation agent injection rates. Catalytic performances were tested at various temperatures, with a gas composition ratio of CH4:CO2:H2O = 1:0.67:3 and a gas hourly space velocity (GHSV) of 647,000 mL h-1 gcat-1. The rate of precipitation agent injection influenced the characteristics of the catalysts depending on the type of support used. As the temperature increased, both the CO2 reforming of methane and the reverse water gas shift reactions occurred. The Ni-Al2O3 catalyst, synthesized with a single injection of the precipitation agent, exhibited the best catalytic activity under conditions with sufficient steam supply among the prepared catalysts, due to its high Ni dispersion.
