  "description": "<p>A 100 kWth dual fluidized bed steam gasification pilot plant has been developed at TU Wien to convert<br>\ndifferent types of biogenic fuels into a valuable product gas. In this paper, the conversion of different biogenic<br>\nfuels in combination with the utilization of CO2 as alternative gasification agent was investigated in the<br>\nmentioned pilot plant. For this purpose, five experimental campaigns were carried out aiming at the investigation<br>\nof softwood as reference fuel, and rapeseed cake, bark and lignin as alternative fuels. Pure olivine as<br>\nwell as a mixture (90/10 wt%) of olivine and limestone were used as bed materials. The product gas compositions<br>\nof the different biogenic fuels changed depending on the elemental composition of the biogenic fuels.<br>\nThus, a high amount of carbon in the fuel enhanced CO formation, whereas an increased content of oxygen<br>\nled to higher CO2 contents. Additionally, the presence of alkali metals in the biomass ash favoured the<br>\nproduction of CO. The addition of limestone enhanced the H2 and CO contents via the water gas shift reaction<br>\nas well as steam and dry reforming reactions, but had no significant effect on tar contents. Overall, this paper<br>\npresents the feasibility of the dual-fluidized bed gasification process of different biogenic fuels with CO2 as<br>\ngasification agent.</p>",
