Abstract

The production of synthetic gas and alternative liquid fuels, based on renewable and waste source materials, is an emerging topic. With growing energy demand and increasing CO₂ concentration within the atmosphere, caused by excessive fossil fuels combustion, alternative ways of energy utilisation, storage and transformation are intensely being sought and developed. Combining technologies of gasification and Fischer–Tropsch catalytic synthesis of biomass/waste materials can provide not only a possibility to replace fossil fuels extraction, but it can partially solve the issue of growing amounts of unprocessed waste materials. The 200 kW power input technology for gasification of biomass/waste materials with sliding bed, cross/updraft reactor was used to perform experimental measurements of conversion of waste materials into producer gas. This gas, with potential to be used as a source gas for catalytic synthesis was examined from quality and safety points of view. The composition and suitability for its utilisation was evaluated, as well as safety assessment in terms of its explosivity was determined. The latter mentioned was carried out in 1 m³ spherical explosion vessel to determine pressure rise during the explosion of the producer gas. The results showed interesting differences between measured data and mathematical model, probably caused by the presence of other substances, such as tar compound, solid particles and other pollutants.
