    摘要： A method for applying a washcoat suspension to a support structure. To provide coatings with largely uniform thickness starting from washcoat suspensions, the method uses a device (10) set up to produce, by means of a process gas (40), a fluid bed of support structures in which the support structures circulate elliptically or toroidally, the method comprising the steps of: a) charging the device (10) with support structures and producing a support-structure fluid bed by means of a process gas (40), wherein the support structures circulate in the fluid bed elliptically or toroidally, preferably toroidally; b) impregnating the support structures with a washcoat suspension by spraying the support structures circulating elliptically or toroidally in the fluid bed with the washcoat suspension; c) drying the support structures sprayed with the washcoat suspension; and d) optionally calcining the support structures loaded with the solids contents of the washcoat suspension.

    摘要： A disk-shaped wafer is described which is based on an inorganic sorbent and a binder, with a thickness of less than 700 microns, which can be obtained by pressing a mixture of the inorganic sorbent, about 20 to 60% by weight of the binder and about 10 to 15% by weight water at a pressure of at least 70 MPa; and calcining the resulting green wafer at temperatures of at least about 500° C. until the water content is substantially removed.
