Tiivistelmä
In this bachelor’s thesis, co-gasification of solid recovered fuel and biochar for synthesis gas production was performed and the quality of the produced synthesis gas was investigated. The bachelor’s thesis was commissioned by the VTT Technical Research Centre of Finland. The bench scale test runs were executed on the BFB100 pilot platform at the VTT Bioruukki pilot center.
The project aimed to successfully produce synthesis gas using the bubbling fluidized bed gasifier pilot platform, and especially to investigate the effect of the used co-fuel, biochar, on the quality of the synthesis gas when solid recovered fuel was used as the main fuel. The bachelor’s thesis aimed to gather information on the basics of gasification, its applications, different technologies related to gasification and the possibilities for synthesis gas utilization. The benefits and potential of waste and biomass as feedstocks for gasification were also examined, as well as the emerging technologies and main key process developers of waste gasification were explored. The focus was then on the implementation of these co-gasification test runs, and mass balance calculations and various analyses were used to obtain the results of the co-gasification test runs and the produced synthesis gas.
The use of waste and biomass as feedstock for gasification has become increasingly popular due to its sustainability. VTT wants to be a part of the future transition towards more sustainable gasification. In addition to the use of solid recovered fuel, the aim was to find the positive effects of using biochar as a co-fuel in terms of more sustainable gasification and the quality of the produced synthesis gas.
