Abstract
The influence of various methods of chemical treatment of coal on its behaviour in inert media and in water vapour has been shown. It has be en found that during pyrolysis in inert medium, chemical modification permits variation of the yields of pyrolysis products over a wide rang e. The attack of coal organic matter (COM) by the water molecule becom es a principal reaction in water vapour. Evidence in favour of the hyp othesis for chemical interaction of water vapour with COM paramagnetic centres (PMC) has been obtained.
