Abstract [en]

In this paper a new type of black liquor gasification is presented and discussed. It is a CirculatingFluidized Bed process with the addition of TiO2 to the bed material. This gives a directcaustization of Na2CO3 to Na2O.TiO2 which forms NaOH by leaking with water. Thus a lime kilnis not needed. Simultaneously also SO4 is reduced to S2- and stripped off as H2S to a major extent,absorbed in a selective scrubber, giving a separation of OH- and S2- .This makes modifiedcooking possible. The produced synthetic gas can be used to run an efficient Integrated Gas-Combi Cycle (IGCC), up to 37 % electric efficiency, or use the gas for production of differentchemicals like NH3, DME pr Methanol. These aspects are discussed as well in the paper.
