Abstract:Coal gangue is rich in kaolin clay minerals, which can be used as raw materials for the preparation of adsorbents and intermediates of adsorbents, and is important for the high added value utilization of coal gangue. In this study, coal gangue from southern Sichuan, China, was activated and characterized by calcination at 100~900 °C, and the succession laws of the phase, microstructure and physical properties under thermal activation conditions were studied. Results showed that the content of active hydroxyl g… Show more
