Abstract

Monomodal or polymodal catalyst supports or catalysts having a BET specific surface area of from 0.01 to 250 m.sup.2 /g and a monomodal or polymodal pore size distribution having a mean pore diameter of from 50 to 300,000 nm measured by the mercury pressure porosimetry method, wherein PA1 a) from 10 to 95% of the pore volume is at from 0.2 to 100 times the mean pore diameter and/or PA1 b) from 10 to 80% of the pore volume is at from 0.8 to 100 times the mean pore diameter and/or PA1 c) from 50 to 95% of the pore volume is at from 0.2 to 1 times the mean pore diameter and/or PA1 d) from 50 to 80% of the pore volume is at from 0.8 to 1 times the mean pore diameter and PA1 e) the width at half height of the pore size distribution is less than 0.6 times the mean pore diameter, which are useful for the preparation of chlorine from hydrogen chloride in a non-steady-state Deacon process, for the reaction of ethylbenzene to give styrene in a non-steady-state oxydehydrogenation, for preparing aziridine from ethanolamine, in reductions, hydrogenations, oxidations, dehydrogenations, acid- or base-catalyzed reactions or reactions in a fluidized bed, for removing combustion residues from diesel…
