Co-gasification of petroleum coke and biomass.

Highlights: [•] Co-gasification of biomass and petroleum coke in an atmospheric bubbling fluidised bed and thermogravimetric analyzer. [•] Synergetic effect between biomass and petroleum coke was observed. [•] The activation energy for pure petcoke is 121.5kJ/mol, for the 50/50 blend it is 96.3, and for the 20/80 blend – 83.5kJ/mol. [•] Biomass ash has a catalytic effect on the reactivity of petcoke due to the alkali and alkaline earth metals present in ash. [Copyright &y& Elsevier]
