FIELD: chemistry.
SUBSTANCE: invention relates to a method of producing acrolein by dehydrating glycerol. The method is carried out in the presence of solid-phase catalysts containing tungsten compounds with Hammett pH Ho less than +2, which contain palladium as a promoter. The catalyst is periodically regenerated separately in time from the glycerol conversion reaction and continuously regenerated separated in space from the glycerol conversion reaction, and for regeneration thereof, the catalysts are subjected to an oxidative or reducing atmosphere.
EFFECT: method of regenerating a catalyst which is suitable for dehydration of glycerol, which exhibits low susceptibility to coking with possibility of easy regeneration thereof.
