No.75 Development of Low Temperature Carbonization and Ashing Process using Ni based Catalyst

Abstract

In this study, we developed a low temperature chicken manure ashing and carbonization process. Feature of this process is reforming of tar produced through low temperature ashing and carbonization by Ni based catalyst installed in the furnace. High calorie gas produced by the tar reforming is burned out and then the exhausted hot gas is utilized as heat source of the furnace. We installed a plant with the capacity of 1 ton/day at poultry farmers and demonstrated continuous operation at 600 ℃ for 100h without fatal trouble. Ash and carbonaceous material obtained through the process has suitable properties as a fertilizer.
