Gasification
Unlike pyrolysis, gasification is the conversion of biomass into combustible gas mixture at high temperature range of 700–1000 °C, with a controlled amount of oxygen and/or steam (partial oxidation). The resulting gas mixture is called synthesis gas or syngas. This conversion process is expressed as [34]:

biomass+heat→H2+CO+CO2+CH4+hydrocarbon+char
