  • 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: 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: 20050148487
    Abstract: Inventions described herein generally relate a process for contacting a polymeric feed with one or more inorganic salt catalysts to produce a total product comprising a liquid product and, in some embodiments, non-condensable gas. In some embodiments, the inorganic salt catalyst exhibits an emitted gas inflection of an emitted gas in a temperature range between 50° C. and 500° C., as determined by Temporal Analysis of Products. In some embodiments, the inorganic salt catalyst has a heat transition in a temperature range between 200° C. and 500° C., as determined by differential scanning calorimetry (DSC), at a rate of 10° C. per minute. Inventions described herein also generally relate to compositions that have novel combinations of components therein.
