Tar and Trace Element Measurements in Synthesis Gas from a Pressurized Black Liquor Gasifier

A.C. Johansson, O.G.W. Öhrman, E. Pettersson & D. Sweeney
Tar formation is one of the major challenges associated with biomass gasification. Tar is an undesirable product both due to technical issues but also due to environmental issues. In addition to tars, other trace elements originating from the biomass feedstock can become problematic for catalytic upgrading into synthetic fuels. Therefore, the concentration of tar and trace elements in the cold synthesis gas from a pressurized entrained flow black liquor gasifier located in Piteå, Sweden, were...
