Air–steam gasification produced syngas with slightly improved lower heating value of 4.5 MJ/mN3 in comparison to 4.4 MJ/mN3 produced during air gasification. The corresponding tar generation for air gasification and air–steam gasification was 21.2 g/mN3 and 26.2 g/mN3, respectively. Cold gas efficiency for air gasification and air–steam gasification was realized to be 91% and 91.4%, respectively. Carbon conversion during air–steam gasification reached about 91.5% while carbon conversion during air gasification was limited to 84.3%.enBiomass gasificationUpdraftAuto-thermalPacked bed reactorJournal Article, Peer Revieweddoi:10.1016/j.fuproc.2015.07.015
