PYROLYSIS OF SPENT PULPING LIQUORS ABSTRACT OF THE DISCLOSURE The present invention discloses a process of pretreat- ing a waste black liquor which results from the pulping of vari- ous vegetative fibers and wherein the pulping liquor contains as its active pulping ingredient sodium and sulfur with the pretreatment taking place prior to the subjecting of the waste black liquor to a hydropyrolysis reaction. The method and the materials used in the pretreatment are derived from the reac- tion products resulting from the hydropyrolysis reaction. The pretreatment serves to enable one to regenerate the inorganic chemical values to a pulping liquor in an easy and economical manner and the pretreatment, also, serves to appropriately ad- just the physical and chemical characteristics of the char pro- duced in the hydropyrolysis reaction. This is accomplished primarily by utilizing the products resulting from the hydro- pyrolysis reaction. -1-
