                      biomass is currently being studied as a potentially
                      sustainable and economically viable process to produce fuels
                      and other vital chemicals. In the process chain the
                      gasification is integrated and straw is converted via
                      pyrolysis into a bioslurry consisting of a liquid, tar-rich
                      phase and char. Afterwards, the slurry is gasified into a
                      tar-free, low-methane syngas which is a basic reactant for
                      the synthesis of biofuels. At the high temperatures over
                      1200 °C the ash constituents of the char in the bioslurry
                      melt and flow down the inner wall as slag. The slag
                      viscosity has to be in a certain range to form a protective
                      layer at the reactor wall and to guarantee a continuous
                      removing. For this reason, the composition of the molten ash
                      at the reactor wall has to be well known. Due to several
                      fractionation processes in the gasifier the composition of
                      the slag at the reactor wall does not correspond directly
                      with the slurry ash. Therefore, experiments were conducted
                      to identify depletion and enrichment processes in the
                      gasifier. Finally, the composition of the slag at the
                      reactor wall is obtained and can be used for the adjustment
                      of the viscosity.},
