<p>One exemplary embodiment can be a process for reducing one or more insoluble solids in a black liquor. The process may include hydrothermal processing the black liquor to a temperature of 250 - less than 300° C for an effective time to reduce the one or more insoluble solids by more than 40%, by weight, based on a weight of the one or more insoluble solids prior to hydrothermal processing.</p> |
