The carbon dioxide gasification characteristics of biomass char samples and their effect on coal gasification reactivity during co-gasification

•Biomass chars reactivities significantly greater than that of coal char.•Biomass- and coal-char reactivities correlate well with some char properties.•10% biomass char addition did not influence coal char gasification rate.•20 and 30% addition of biomass impacted coal char gasification behaviour.•S...
