Claims27
A supported catalyst for conducting a fluid phase catalytic chemical reaction comprising
- (a) a catalyst support comprising a carbon fibril aggregate, said fibril aggregate comprising a plurality of carbon fibrils having an outer region of multiple, essentially continuous, generally parallel layers of ordered carbon atoms that are graphitic;
- and
- (b) a catalytically effective amount of a catalyst supported on said aggregate.
A supported catalyst for conducting a fluid phase catalytic chemical reaction comprising (a) a catalyst support comprising a carbon fibril aggregate, said fibril aggregate comprising a plurality of carbon fibrils having an outer region of multiple essentially continuous, generally parallel layers of ordered graphitic carbon atoms disposed substantially parallel to the central axis of said fibril, said fibrils having an external diameter of about 3.5 to 75 nanometers and a length to diameter ratio of at least 5, and;
- (b) a catalytically effective amount of a catalyst supported on said aggregate.
A process for making a supported catalyst for conducting a fluid phase catalytic chemical reaction comprising depositing a catalytically effective amount of a catalyst on a carbon fibril aggregate that comprises a plurality of carbon fibrils, which have an external diameter of about 3.5 to about 75 nanometers, a length-to-diameter ratio of at least about 5 and graphitic layers, wherein said catalyst is a multicomponent catalyst comprising at least one catalytic metal deposited on at least one support particle dispersed throughout said carbon fibril aggregate.
