Abstract:
Supported noble metal-comprising catalysts which can be obtained by a1) application of a noble metal compound, optionally in admixture with additives acting as promoters, to a support material, then drying, and a2) application of a reducing agent to a support material, then drying, wherein steps a1) and a2) are repeated simultaneously or in alternating turns, or wherein either of the compounds is applied entirely and then the other one is applied entirely, b) optionally afterwards drying of the resulting product, and c) subsequent calcination, its use, especially for oxidative dehydrogenation and a process for producing it.
Abstract:
The present invention relates to a porous inorganic body comprising pores A having a pore size SA in the range of from 0.005 to 20 micrometer and a total pore volume VA, and comprising pores B having a pore size SB in the range of from more than 20 to 1000 micrometer and a total pore volume VB, wherein the total pore volume of the pores having a pore size in the range of from 0.005 to 1000 micrometer is VC and wherein the ratio RA=VA/VC is in the range of from 0.3 to 0.7 as determined via mercury intrusion porosimetry.
