  • Publication number: 20070295643
    Abstract: A system to produce a total product and recover inorganic salts from a combustion gas is described. The system includes a contacting zone, a regeneration zone and a recovery zone. The contacting zone is configured to fluidize a supported inorganic salt catalyst in the presence of a feed, steam, and a hydrogen source to produce the total product. The regeneration zone is configured to receive at least a portion of the supported inorganic salt catalyst from the contacting zone and remove at least a portion of contaminants from the supported inorganic salt catalyst. The recovery zone is configured to receive combustion gas from the regeneration zone, wherein the recovery zone is configured to separate at least a portion of inorganic salts from the combustion gas.

  • Publication number: 20070295641
    Abstract: Methods of producing a total product are described. A method includes contacting a feed with light hydrocarbons in the presence of one or more inorganic salt catalysts and steam to produce a total product; controlling contacting conditions such that at least 50% of the light hydrocarbons are recovered; and producing a total product, wherein the ratio of atomic hydrogen to carbon (H/C) in the total product is between 80% and 120% of the atomic H/C of the feed.

  • Publication number: 20070295647
    Abstract: Methods of producing a total product are described. A method includes contacting a feed with a hydrogen source in the presence of one or more inorganic salt catalysts and steam to produce a total product; and controlling contacting conditions such that the conversion of feed to hydrocarbon gas and hydrocarbon liquid in the total product is between 5% and 50%, based on the molar amount of carbon in the feed.

  • Publication number: 20070295645
    Abstract: Methods of producing a crude product are described. A method includes providing a feed and a supported inorganic salt catalyst to a contacting zone. The feed has at total content, per gram of feed, of at least 0.9 grams of hydrocarbons having a boiling range distribution between 343° C. and 538° C. Contact of the supported inorganic salt catalyst with the feed in the presence of a hydrogen source and steam is performed such that the supported inorganic salt catalyst becomes fluidized, and a total product that includes a crude product is produced. The crude product has a total content of at least 0.2 grams per gram of crude product of hydrocarbon have a boiling range distribution between 204° C. and 343° C.

  • Publication number: 20070012595
    Abstract: Methods of producing a total product are described. A method includes continuously contacting a feed with a hydrogen source in the presence of one or more inorganic salt catalysts and steam to produce a total product, wherein the feed has at least 0.02 grams of sulfur, per gram of feed; and producing a total product that includes coke and the crude product. The crude product has a sulfur content of at most 90% of the sulfur content of the feed.
