ZnClq and AICl3 catalyse the cleavage of aliphatic linkages between aromatic nuclei but not the cleavage of direct aryl-aryl bonds between such nuclei. The rate of alkyl-aryl bond breakage depends on the Bronsted acidity of the active catalyst (e.g. H+(ZnCl2X)-or H+(AlCl3X)-) and the Bronsted basici

Seven kinds of coals (C, 77.S89.8 wt% daf) were oxidized with air at 150ยฐC for 1, 5 and 10 h. The oxidized coals were heat-treated at various temperatures between 300 and 1500ยฐC with intervals of 50 or 100ยฐC. The pore-structure of the oxidized coals and the cokes or chars obtained from the oxidized
