Methods for producing a total product with minimal uptake of hydrogen

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.

1 . A method of producing a total product, comprising: 
 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 a 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.    
     
     
         2 . The method of  claim 1 , wherein the contacting conditions are also controlled such that a ratio of carbon monoxide to carbon dioxide ranges from 1 to 4.  
     
     
         3 . The method of  claim 1 , wherein the light hydrocarbons comprise methane and/or hydrocarbons having a carbon number ranging from 2 to 6.  
     
     
         4 . The method of  claim 1 , wherein the atomic H/C in the total product is between 90% and 110% of the atomic H/C of the feed.  
     
     
         5 . The method of  claim 1 , wherein the contacting conditions are controlled such that the amount of light hydrocarbons recovered is between 50% and 99%.  
     
     
         6 . 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.  
     
     
         7 . The method of  claim 1 , wherein the inorganic salt catalyst comprises one or more alkali metal carbonates and/or one or more alkaline-earth oxides.  
     
     
         8 . The method of  claim 1 , wherein the inorganic salt catalyst is limestone and/or dolomite.  
     
     
         9 . The method of  claim 1 , wherein the inorganic salt catalyst is supported, and the support comprises limestone, carbon, coke, nonvolatile charcoal, activated carbon, fly ash, dolomite, clay, TiO 2 , ZrO 2 , aluminosilicate, spent hydroprocessing catalyst, metals and/or compounds of metals recovered from the a total product/feed mixture, one or more metals from Columns 5-10 of the Periodic Table, one or more compounds of one or more metals from Columns 5-10 of the Periodic Table, or combinations thereof.  
     
     
         10 . The method of  claim 1 , wherein the contacting zone is a circulating fluidized bed and/or a circulating fluidized riser.  
     
     
         11 . The method of  claim 1 , wherein the feed has a total asphaltenes content of at least 0.01 grams of asphaltenes per gram of feed.  
     
     
         12 . The method of  claim 1 , wherein the feed has a total residue content of at least 0.01 grams per gram of feed.  
     
     
         13 . The method of  claim 1 , wherein the feed has at least 0.1 grams of hydrocarbons having a boiling point below 538° C., per gram of feed.  
     
     
         14 . The method of  claim 1 , wherein the contacting is performed in the presence of hydrogen sulfide.  
     
     
         15 . The method of  claim 1 , further comprising providing the total product to a separation zone, wherein the total product is separated into crude product and/or gas.  
     
     
         16 . The method of  claim 1 , wherein the total product includes a crude product and the crude product has greater than 0 grams but less than 0.01 grams of the inorganic salt catalysts per gram of crude product.  
     
     
         17 . The method of  claim 1 , wherein the total product comprises a crude product, and the method further comprises fractionating the crude product into one or more distillate fractions, and producing transportation fuel from at least one of the distillate fractions.
