| 1. A plate-shaped pressed body with a thickness of less than about 700 μm, comprising an inorganic sorbent and a binder wherein
the pressed body is obtained by the process comprising the steps of
compressing a mixture comprised of the inorganic sorbent and the binder at a pressure of at least about 70 MPa, wherein the
weight ratio of the sorbent to the binder in the mixture is between about 4:1 and 0.7:1 when measured on a dry weight basis
and wherein the water content of the mixture determined at 160° C. is between about 8 and 20 percent, and
calcining the resulting compressed mixture at a temperature of at least about 500° C. to form the pressed body, wherein water
contained in the calcined pressed body is less than about 2 percent.
