000150720 5203_ $$aDecarbonizing the industry is key to achieving goals against climate change. The use of synthetic fuels and their regeneration is promoted, utilizing the industry's own emissions. However, implementing processes like carbon dioxide methanation for synthetic natural gas generation is a challenge in these industries due to the presence of impurities, such as sulfur. The objective of this study is to compare different supports and promoters for a nickel-based CO2 methanation catalyst at various levels of sulfur poisoning (0–1 wt%). Based on the results obtained, alumina emerged as the optimal catalyst support, showcasing superior catalytic performance compared to other tested materials across all examined reaction temperatures. Additionally, calcium (1 wt%) was identified as the most effective promoter, demonstrating the highest performance not only in unpoisoned catalysts but also when comparing samples with 1 wt% of sulfur poisoning. Additionally, the first sulfur-dependent kinetic model for methanation was developed, for the best Ni/Support and Ni/Promoter/Support catalyst. The kinetic model is valid for 0 – 1.0 wt% S poisoning, 1 bar, 200 – 450 °C, and 86 100 ml h−1 gcat−1 (error within ±5 %).
