Basic studies on black-liquor pyrolysis and char gasification

Thermodynamic equilibrium analysis of entrained flow gasification of spent pulping liquors

“…Previously, Berglin [23] used a simplified thermodynamic equilibrium model only for the gas phase, aiming to study the performance of air-blown BLG for electricity production. Other thermodynamic equilibrium studies of BLG included slag species in the models [7,10,[24][25][26]. However, the few studies that compared their results to experimental data only focused on equilibrium gas composition and did not validate the composition of the inorganic phase [7,10].…”

Utilization of Urban and Pulping Wastes to Produce Synthetic Fuel via Pyrolysis

“…Gasi cation of black liquor has been investigated by some researchers. Pressurized gasi cation of these liquors, in combination with combinet-cycle generation of electricity, is an attractive alternative for improving the electrical/thermal ratio for energy recovered from these fuels (Backman et al, 1993). In a gasi cation system the organic matter in black liquor is converted to a clean gaseous fuel suitable for combustion in a gas turbine (Salmenoje, 1993).…”

Biohydrogen

“…Chemically, black liquor is a mixture of several basic elements where the largest fractions are carbon, oxygen, sodium and sulfur. The black liquor composition was assumed to be C 10 H 12.5 O 7 Na 2.4 S 0.36 (Backman et al, 1993;Salmenoja, 1993). The black liquors can be converted to gaseous, liquid and char products by pyrolysis.…”
