Increase of high-sulphur coals quality with the help of high pressure water

摘要

The development of various processes of obtaining diverse chemical products out of coal places severe requirements upon economic and ecological aspects taking into account the fact that only high-sulphure and high-ash coals will be involved in processing. In this connection one of the most important conditions is the prelimianry preparation (benefication) of coals to further processing, namely, the mechano-chemical activation of material structure of coal. One of the perspective modes of mechanochemical activation of coals is their processing with high pressure water jets.
