The B modification (0.5–3 wt%) on zirconia was found to increase the catalytic activities of Co catalyst during methanation. The B modification resulted in (i) preventing the agglomeration of Co oxide species, and (ii) increasing the dispersion of Co oxide species. Only a slight decrease in C2–C4 selectivity was observed.
Boron modification on MCM-41-supported cobalt (Co) catalysts was found to decrease the catalyst activity during CO hydrogenation. The decreased activities were due to stronger support interaction between Co oxide species and the support with the presence of boron resulting in lower reducibility. However, based on methanation the selectivity to C2–C4 products slightly increased with low loading of...
