Abstract

A Fischer-Tropsch catalyst comprising a catalytically active first metal selected from the group consisting of at least one metal selected from the group consisting of iron, nickel, cobalt, chromium, and mixtures thereof, at least one second metal selected from the group consisting of silver, iron, zinc, copper, platinum, zirconium and combinations thereof; and a matrix structure comprising a polymer selected from the group consisting of polyacrylates and polymethacrylates. The first and second metals are incorporated into the polymer.

Claims

exact text as granted — not AI-modified
What is claimed is:

         7 . The process of  claim 6  wherein the polymer is pretreated in hydrogen.  
     
     
         8 . The process of  claim 6  wherein the polymer is pretreated in hydrogen at a temperature above 300° C. for at least 0.5 hours.  
     
     
         9 . A Fischer-Tropsch catalyst comprising: 
 a catalytically active first metal selected from the group consisting of at least one metal selected from the group consisting of iron, nickel, cobalt, chromium, and mixtures thereof;    at least one second metal selected from the group consisting of silver, iron, zinc and zirconium and combinations thereof; and    a matrix structure comprising a polymer selected from the group consisting of polyacrylates and polymethacrylates;    wherein the first and second metals are incorporated into the polymer.    
     
     
         10 . The catalyst of  claim 9  wherein the first metal is cobalt.  
     
     
         11 . The catalyst of  claim 10  wherein the second metal is silver.  
     
     
         12 . The catalyst of  claim 9  wherein the first metal comprises from about 0.1 to 50 mole percent of the matrix metal and catalyst metal combined.  
     
     
         13 . The catalyst of  claim 10  wherein the first metal comprises from about 10 to 50 mole percent of the matrix metal and catalyst metal combined.
