The co‐pyrolysis and co‐gasification of binary blends of a bituminous coal (PT), a petcoke (PC) and two types of biomass (olive stones, OS; chestnut, CH) were studied at atmospheric pressure in a fixed bed reactor. The pyrolysis and gasification were performed under nitrogen, and steam/oxygen atmospheres, respectively. In a fixed bed reactor, the particles of the different fuels are in close contact, providing an optimum means for evaluating possible synergetic effects. Pyrolysis tests showed a lack of chemical interaction between the components of the blend. Therefore, the composition of the gas produced during the pyrolysis tests can be predicted from those of the individual components and their mass fractions. During the co‐gasification tests, different interactions were observed depending on the heating rate. Low heating rates produced higher amount of CO and CO 2 , whereas tar yield decreased. At high heating rates, the biomass and coal blends produced more tar but less H 2 and CO. The effect of co‐gasification on apparent thermal efficiency was also evaluated. © 2012 Society of Chemical Industry and John Wiley & Sons, Ltd
