Briquetting of Konya-Ermenek lignite of Turkey

Abstract

Abstract As a utilization technology for fragile Turkish lignites briquetting may be considered. For this reason Konya-Ermenek lignite was subjected to cold and hot and binder- and binderless-type briquetting. The hot and cold binderless briquettes failed to meet the necessary product quality. Atactic propylene, sulphite liquor, molasses and coal tar pitch were used as binders and coal tar pitch briquettes were found to be the best quality products. The effect of moisture, briquetting pressure, heat treatment and aging were also investigated.
