Production of metallurgical cokes from some Turkish lignites using sulphite liquor binders

Abstract

Soma and Tunçbilek lignites were briquetted at 80 °C under 0–100 MPa, using varying amounts of sulphite liquor binders. The briquettes were then carbonized at 950 °C, and the resulting formed cokes were examined. The effects of the type and concentration of binders, and of the briquetting pressure, on the strength and porosity of the formcokes were investigated. As a result of these experiments, optimal briquetting conditions were established. It was also stated that formcokes made from both Turkish lignite samples under optimal briquetting conditions could be used for metallurgical purposes, particularly in non-ferrous metallurgy.
