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