Active carbons and clean briquettes from the modified kansk-achinsk brown coal

摘要

The effect of modification of Kansk Achinsk Brown coal by means of chemical and mechanical pretreatments as well as by hydrolized lignin addition on coal briquetting was studied.Coal briquettes were then pyrolyzed and steam activated at 700-800 C to prepare the active carbons.The main focus was to analyse how macromolecular structure of brown coal affect the properties of briquettes and the sorption and mechanical properties of activated carbons and to investigate the potential for the production of clean briquetted fuel and high performance carbon adsorbents through the directive modification of coal.
