Methods for producing a total product with selective hydrocarbon production

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.

1 . A method of producing a total product, comprising: 
 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.    
     
     
         2 . The method of  claim 1 , wherein the total product also includes carbon oxide gases, and the contacting conditions are also controlled such that conversion of feed to carbon oxide gases is between 55% and 95%, based on the molar amount of carbon in the feed.  
     
     
         3 . The method of  claim 1 , wherein the inorganic salt catalyst comprises one or more alkali metals, one or more compounds of one or more alkali metals, one or more alkaline-earth metals, one or more compounds of one or more alkaline-earth metals or combinations thereof.  
     
     
         4 . The method of  claim 3 , wherein the conversion of feed to hydrocarbon gas and hydrocarbon liquid in the total product is between 5% and 30%.  
     
     
         5 . The method of  claim 3 , wherein at least one of the inorganic salt catalysts is a mixture of one or more alkaline-earth metal oxides.  
     
     
         6 . The method of  claim 5 , wherein at least one of the inorganic salt catalysts is calcium oxide.  
     
     
         7 . The method of  claim 5 , wherein at least one of the inorganic salt catalysts is magnesium oxide.  
     
     
         8 . The method of  claim 7 , wherein the conversion of feed to hydrocarbon liquids and hydrocarbon gases is at most 20%.  
     
     
         9 . The method of  claim 3 , wherein at least one of the inorganic salt catalysts is a mixture of one or more alkali metal carbonates.  
     
     
         10 . The method of  claim 3 , wherein at least one of the inorganic salt catalysts is mixture of one or more a alkali metal carbonates and one or more alkaline-earth metal oxides.  
     
     
         11 .

         12 . The method of  claim 1 , further comprising varying a weight ratio of steam to feed to alter the carbon monoxide to carbon dioxide ratio.  
     
     
         13 . The method of  claim 1 , further comprising varying a weight ratio of steam to feed to alter a hydrocarbon gas to crude product ratio.  
     
     
         14 . The method of  claim 1 , further comprising varying a flow rate of steam alter a hydrocarbon gas to crude product ratio.
