The steam reforming of naphthalene over a nickel–dolomite cracking catalyst

With naphthalene as a model compound, catalytic cracking experiments on biomass tar were made on Ni–dolomite catalysts. The performance of catalyst preparation, activity, coke formation and regeneration were analysed. The results showed that the ratio of the one-step conversion of naphthalene was 95% at space velocity 0.81 h−1 and 700 °C; with saturated wet air as regeneration gas, the regeneration time was within 0.5 h; compared with thermal cracking at the same reaction temperature, the catalytic cracking was propitious to deep cracking of naphthalene.
