  • Plate-shaped pressed bodies
    Patent number: 7585430
    Abstract: There is disclosed a plate-shaped pressed body (wafer) produced from an inorganic sorbent and a binder, having a thickness of less than 700 ?m, which is produced by the process of compressing a mixture of the inorganic sorbent, the binder, and optionally water and compression aids at a pressure of at least 70 MPa, wherein the weight ratio of dry sorbent to dry binder is between about 4 and 0.7 and the water content of the mixture, measured at 160° C., is between 8 and 20%; and calcining the resulting pressed body at temperatures of at least about 500° C., until the water content is substantially removed.
    Type: Grant
