ABSTRACT:
Fine-grained solids including dust-like solids are introduced into a reaction space which is under pressure such as used in the gasifying of coal is effected by mixing carbon dioxide in the form of dry ice with the solids after the solids have been precooled to a temperature of -80.degree. C., then bringing the formed mixture of solids and dry ice up to the pressure required for introduction into the reaction space, thereafter subjecting the dry ice to sublimation to separate it from the solids and subsequently, after pressure release and cooling to the desublimation comparative, reconverting the gaseous carbon dioxide into dry ice which then is circulated into the next run while the solids are passed into the reaction space.
