Abstract

âº Catalyst carbon resistance was improved by lanthanide (Ce, Pr, Sm) oxide promotion. âº Carbon deposition rate dropped with temperature within 923-1023Â K in all catalysts. âº Carbon deposition rate reaction orders linearly correlated with acid:basic site ratio. âº Gasification kinetics adequately captured by geometrical contracting volume model. âº Complete carbon removal was achieved by either TPR-TPO-TPR or TPO-TPR.
