Abstract
There is presented a catalyst support that has a substantially spherical body, penetrated with a plurality of tunnels extending from a first end on a surface location of the catalyst body to another end on another surface location of the body. The support is made of alumina or like composition. The catalyst body has a total surface that includes the outer surface and surfaces within the tunnels. This total surface is adapted to receive catalyst composition. The catalyst support is adapted to being packed in a reactor and provides lower packed bed pressure drop.

A catalyst support comprising a substantially spherical body, the spherical body penetrated with a plurality of tunnels extending from a first end on one surface location of the substantially spherical body to a second end on another surface location of the substantially spherical body, the spherical body comprising a total surface including an outer surface and surfaces within the plurality of tunnels, the total surface comprising a surface adapted to receive thereon a catalyst composition, the catalyst support adapted to packing in a tubular bed within a packed bed reactor thereby reducing catalyst bridging as compared to cylindrical catalyst, and the catalyst support adapted to provide a lower pressure drop for the same bed height as compared to dimensionally similar cylindrical catalyst that also have tunnels, and higher conversion rate than cylindrical catalyst.
A catalyst support comprising a substantially spherical body, the substantially spherical body penetrated with a plurality of tunnels extending from a first end on one surface location of the spherical body to a second end on another surface location of the substantially spherical body, the substantially spherical body comprising a total surface including an outer surface and surfaces within the plurality of tunnels, the total surface adapted to receive thereon a catalyst composition, the catalyst support adapted for packing in a bed within a tubular bed of a packed bed reactor thereby reducing catalyst bridging in the tubular bed as compared to cylindrical catalyst, and the catalyst support adapted to provide a lower pressure drop for the same bed height as compared to dimensionally similar cylindrical catalyst that also have tunnels, and higher conversion rate than cylindrical catalyst.
A catalyst support comprising a substantially spherical body, the substantially spherical body penetrated with from 3 to about 7 tunnels extending from a first end on one surface location of the spherical body to a second end on another surface location of the substantially spherical body, the tunnels each having an internal diameter ranging from about 8 to about 20% of the diameter of the spherical body;
- the substantially spherical body comprising a total surface including an outer surface and surfaces within the tunnels, the total surface comprising a surface adapted to receive thereon a catalyst composition comprising any one or more of surfaces thereof a catalyst selected from the group of metals consisting of nickel, cobalt, platinum, ruthenium, palladium, ruthenium, copper, zinc, iron and mixtures and alloys thereof, the catalyst support adapted for packing in a bed within a tubular bed of a packed bed reactor thereby reducing catalyst bridging as compared to cylindrical catalyst, and the catalyst support adapted to provide a lower pressure drop for the same bed height as compared to dimensionally similar cylindrical catalyst that also have tunnels, and higher conversion rate than cylindrical catalyst.
