摘要： A process for the preparation of a granulated or pelletized weak anion exchange medium from a phenol-containing organic material like peat, followed by low-temperature torrefaction of the granules to produce a high degree of physical stability of the granules at high-pH conditions, followed by chemical pretreatment of the stable granule via a hydrolysis reaction, and optionally surface treatment with acids, followed by the main chemical treatment of the hydrolyzed granule via separate aldehyde and amine reagents, or alternatively via an adduct reagent like hexamethylenetetramine is provided by this invention. The weak anion exchange medium of this invention can be used in a variety of aqueous solution treatment processes, such as wastewater treatment for removing mineral acids like H2SO4, HNO3, HCl, HBr, HF, H3PO4, HI, or formic acid from the wastewater. The resulting anion exchanger medium is particularly useful for treating wastewaters in a low-pH environment.

摘要： A device for producing dry ice pellets comprises a pressing cylinder, into which an inlet opening for feeding liquid carbon dioxide leads and which is equipped with a die, which has one or more openings, and with a piston, which is longitudinally movable in the pressing cylinder. Liquid carbon dioxide is fed to the pressing cylinder, is expanded at the inlet opening, is at least partially converted into carbon dioxide snow and is pressed against and through the die by the movement of the piston. The die is in the form of a cylindrical body that can be connected to the pressing cylinder and is equipped with feed-throughs, which are oriented parallel to a longitudinal axis of the die and are dimensioned in such a way that the length and the diameters of the feed-throughs correspond to the length and the diameters of the dry ice pellets to be produced.

摘要： A process for preparing granules is disclosed. The process comprises the steps of feeding the input material for granulation in a processor using one or more powder feeders, introducing steam as a granulation activating agent in the processor, granulating the input material in presence of the steam to form granules, and collecting the granules from a discharge zone of the processor. A co-rotating twin-screw processor for preparing granules is also disclosed.

摘要： Methods of simultaneously forming feed particles of different densities involves extruding a heated feed through an extruder having an extruder die defining a plurality of die openings. A first plurality of the die openings comprises a land length that is at least two times as long compared to a diameter of a respective die opening. A second plurality of the die openings comprises a land length that is equal to or less than a diameter of a respective die opening. Extrusion through the first plurality of the die forms extruded ribbons with a first density, while extrusion through the second plurality of the die openings forms extruded ribbons with a second density that is lower than the first density. The method proceeds by cutting the first and second plurality of extruded ribbons to simultaneously form feed particles of the first and second densities.
