Abstract
A catalyst having a core comprising a composite (A) of SiC grains and a protective matrix of one or more metal oxides, such as alumina, in voids between the SiC grains, said core having a density >60% of theoretical density, and a catalytically active layer (C) containing, e.g., Ni adhered to the core. A catalyst support comprising a composite of SiC grains and a protective matrix of one or more metal oxides in voids between the SiC grains is also provided, along with a method of fabricating a catalyst core. The catalyst can be used in Fischer-TRopsch synthesis or in steam methane reforming.
Claims23
A catalyst comprising:
- (a) a core comprising a composite of SiC grains and a protective matrix of one or more metal oxides in voids between the SiC grains, said core having a density ≥60% of theoretical density;
- (b) a catalytically active layer adhered to, and external to, said core;
- and
- (c) an interfacial layer located between the core and the catalytically active layer, wherein the interfacial layer comprises alumina, silica, titania, zirconia, a mixture of two or more of the foregoing, or an oxide compound of two or more of the foregoing.
A catalyst comprising:
- (a) a core comprising a composite of SiC grains and a protective matrix of one or more metal oxides in voids between the SiC grains, said core having a density ≥60% of theoretical density;
- (b) a catalytically active layer adhered to, and external to, said core;
- and
- (c) a gas-tight, hermetic, protective coating located between the catalytically active layer and the core.
