Pyrolytic Processing of Cellulose-Containing Wastes from Food Industry Plants

Abstract

A possible thermal process for disposal of wastes from the brewing and sugar industries was studied. Information on the yields of secondary pyrolysis products (pyrogas, pyroliquid, solid residue) as a function of changes in the processing parameters was obtained. Pyrogas consisting of H₂, CO, CO₂, CH₄, and saturated and unsaturated C₂–C₅ fractions had a heat of combustion of 1.79 and 1.65 MJ/m³ for spent grain and sugar-beet pulp, respectively. A universal unit allowing any type of waste with various quantities of added hydrocarbon waste to be processed was developed.
