CATALYST ON SILICA CLAD ALUMINA SUPPORT |
摘要 |
<p>The invention concerns catalysts comprising (i) a cladded catalyst support comprising (a) a core which comprises alumina particles and (b) about 1 to about 40 weight percent silica cladding, based on the weight of the cladded catalyst support, on the surface of the core; the catalyst support having a BET surface area of greater than 20 m2/g and a porosity of at least about 0.2 cc/g; and (ii) 0.1 to 10 weight percent, based on the weight of the catalyst, of catalytically active transition metal on the surface of the cladded catalyst support; wherein the catalyst support has a normalized sulfur uptake (NSU) of up to 25 ?g/m2. The invention also concerns the production and use of such catalysts.</p> |
