Study of the combined deactivation due to sulfur poisoning and carbon deposition during biogas dry reforming on supported Ni catalyst
This paper presents a detailed study of catalyst deactivation as a result of simultaneous
sulfur poisoning and coke deposition during biogas dry reforming. Experiments are
performed at 700 and 800° C with 5 and 10 ppm of H2S in model biogas with CH4/CO2= 1.5
and 2.0. To assess the relative effect of chemisorbed sulfur in deactivating the supported Ni
catalyst as compared to that of coke deposition, the experiments are performed with and
without H2S in the feed. The catalyst deactivation is found to be faster in the presence of …
