AB Steam reforming of biomass-derived pyrolysis liquids (bio-oil) to produce hydrogen with carbon-based Ni catalysts is gaining attention due to their advantages in terms of cost, sustainability and activity. However, thecatalytic activity at long times on stream is compromised by either coke deposition or gasification of the support.To face these drawbacks, two activated carbons have been studied as Ni catalyst support: a microporous carbonof high purity and a mesoporous carbon with phosphorus surface groups. The activity and long-term stability ofthese catalysts have been studied for the steam reforming of model compounds of bio-oil. The microporoussupport provided a slightly higher H2 production and lower contribution of methanation reaction. However,gasification of this support after 20 h led to a decline in the activity, and massive formation of carbon nanotubesand coke. Nevertheless, the resulting material maintained an outstanding stability with high and stable H2/COratio for 50 h. The P-containing catalyst showed a remarkable long-term stability, but lower H2/CO ratio. Carbongasification was less significant in this catalyst due to the presence of surface phosphorus groups, and thegeneration of nickel phosphides, which hampers the growth of pyrolytic carbon and carbon nanotubes, leading toa superior stability
