✦ Synopsis
In the paper energy crops of considerable cultivation potential in Poland, namely: Salix viminalis, Helianthus tuberosus, Sida hermaphrodita, Spartina pectinata, Andropogon gerardi and Miscanthus X giganteus were tested in terms of steam gasification reactivity of biomass chars, as well as yields and composition of product gas in steam gasification and lime-enhanced steam gasification in a laboratory scale fixed bed reactor at 650 , 700 and 800 C.
The highest value of reactivity for 50% of carbon conversion, R 50 , was observed for Sida hermaphrodita, regardless the process temperature.
Application of CaO for in-situ CO 2 capture in steam gasification of biomass chars resulted in hydrogen content increase at 650 C to the levels comparable with the ones reached at 800 C without carbonation reaction. Also hydrogen and total gas yields increased in tests of lime-enhanced gasification.
