Abstract: Calcined dolomite is a good catalyst in terms of its activity for gasification of residue derived from biomass hydrolysis for hydrogen production, whereas its fragility can cause trouble during operation. A novel modification method aimed at improving the strength of the calcined dolomite has been presented using magnesium nitrate as the modifier, which was introduced into the dolomite via a co-precipitation process. The strength of the modified dolomite can be up to 250 times as high as the unmodified one and can cause much less bed pressure drop and catalyst loss, though the activity is slightly lowered after modification.
