Abstract
An autoclave extraction apparatus where a supercritical fluid is used for supercritical fluid extraction of one or several compounds. The supercritical fluid containing the compoound(s) may then be processed in a pressurized, fluidized, bed reactor under supercritical conditions. The fluidized bed reactor is used to carry out a catalytic reaction of the compound(s). The method is particularly applicable to recover valuable lignin and other extractable components from kraft black liquor.
