Development of a bimetallic dolomite based tar cracking catalyst

Abstract: In this study a bimetallic dolomite based tar cracking catalyst was developed and tested. It was enriched in Ni and Fe with BET surface area of 12.31m2/g. The catalytic characterizations were tested with tar simulated by naphthalene, and with tar produced by biomass and coal co-pyrolysis. 93% naphthalene was decomposed at 950°C. A first order apparent kinetic model was developed. Activation energy of 63.96kJ/mol and pre-exponential factor of 396.2/s were calculated. Furthermore, reduction in char yield by 7%, when the catalyst was used in the biomass–coal co-pyrolysis, was observed. [Copyright &y& Elsevier]
