Abstract
A method and apparatus for converting a hydrocarbon and oxygen containing gas feed stream to a product stream, such as syngas, including catalytically partially oxidizing the hydrocarbon feed stream over a catalyst bed. The catalyst bed has a downstream section which is less resistant to flow than the upstream section.
Claims37
A method for catalyzing the net partial oxidation of a feed stream of hydrocarbons and an oxygen containing gas to produce a product gas, the method comprising:
- providing a plurality of serially aligned stacked zones having at least a first zone and a final zone;
- providing a catalyst support within each zone;
- providing a catalyst on each catalyst support;
- and
- feeding the feed stream through the serially aligned stacked zones;
- wherein the first zone has a first flow resistance;
- wherein each subsequent zone has a flow resistance which is less than or equal to about the flow resistance of the previous zone;
- and
- wherein the final reaction zone has a flow resistance less than the first reaction zone.
A method for catalyzing the net partial oxidation of a feed stream comprising hydrocarbons and an oxygen containing gas to produce a product gas, such as syngas, the method comprising:
- providing a first zone;
- providing a stacked second zone serially aligned with said first zone;
- providing a first catalyst support having a first flow resistance in the first zone and a second catalyst support having a second flow resistance in the second zone, wherein the first flow resistance is greater than the second flow resistance;
- supporting a first catalyst on the first catalyst support and a second catalyst on the second catalyst support;
- feeding the feed stream through the first reaction zone;
- and
- feeding the feed stream through the second reaction zone.
A process for the production of synthesis gas, the method comprising:
- contacting a hydrocarbon-containing gas and an oxygen-containing gas with a syngas catalyst system so as to partially oxidize at least a portion of the hydrocarbon, wherein the catalyst system comprises:
- providing a plurality of serially aligned stacked zones having at least a first zone and a final zone;
- providing a catalyst support within each zone;
- providing a catalyst on each catalyst support;
- and
- feeding the feed stream through the serially aligned stacked zones;
- wherein the first zone has a first flow resistance;
- wherein each subsequent zone has a flow resistance which is less than or equal to about the flow resistance of the previous zone;
- and
- wherein the final reaction zone has a flow resistance less than the first reaction zone.
