Abstract

The invention provides a method for reducing methane formation when hydrocracking hydrocarbons, and a process for the hydrocracking of hydrocarbons, said method and process utilising a non-sulfided hydrocracking catalyst, which catalyst has Ni and Sn, wherein the Ni content is at least 1 mass % and the silica content is at least 20 mass %, present in the form of silica-alumina.

Claims

exact text as granted — not AI-modified
1 . A method for reducing methane formation when hydrocracking hydrocarbons in the presence of a non-sulfided Ni containing catalyst, which catalyst has a Ni content of at least 1 mass % and a silica content of at least 20 mass %, present in the form of silica-alumina.  
   
   
       2 . A method as claimed in  claim 1 , wherein the methane formation is reduced to below 1 mass %.  
   
   
       3 . A method as claimed in  claim 2 , wherein the methane formation is reduced to below 0.1 mass %.  
   
   
       4 . A method as claimed, in  claim 1 , which has a Ni content of at least 3 mass %.  
   
   
       5 . A method as claimed in  claim 1 , which has a Ni content of at least 4.5 mass %.  
   
   
       6 . A method as claimed in  claim 1 , which has at least 40 mass % silica.  
   
   
       7 . A method as claimed in  claim 1 , wherein the catalyst contains Sn.  
   
   
       8 . A method as claimed in  claim 7 , wherein the methane formation is reduced to below 0.01 mass %.  
   
   
       9 . A method as claimed in  claim 1 , wherein the Ni:Sn molar ratio exceeds 1:1.  
   
   
       10 . A method as claimed in  claim 1 , which method includes using silica-alumina as the support for the catalyst.  
   
   
       11 . A process for the hydrocracking of hydrocarbons, said process including exposing said hydrocarbons to a non-sulfided Ni containing catalyst, which catalyst has a Ni content of at least 1 mass % and a silica content of at least 20 mass % and the silica is present in the form of silica-alumina, in a reactor operating at hydrocracking temperatures and pressures.  
   
   
       12 . A process as claimed in  claim 11 , wherein the hydrocarbons are paraffinic hydrocarbons boiling in the 370° C.+ range.  
   
   
       13 . A process as claimed in  claim 11 , wherein the hydrocarbons are lower boiling paraffinic hydrocarbons.  
   
   
       14 . A process as claimed in  claim 11 , which process is operated in the temperature range of 200-450° C., at a pressure of 5-250 bar, and a WHSV=0.1-10 h −1 .  
   
   
       15 . A process as claimed in  claim 11 , which has a Ni content of at least 3 mass %.  
   
   
       16 . A process as claimed in  claim 11 , which has a Ni content of at least 4.5 mass %.  
   
   
       17 . A process as claimed in  claim 11 , which has at least 40 mass % silica.  
   
   
       18 . A process as claimed in  claim 11 , wherein the silica is present in the form of silica-alumina.  
   
   
       19 . A process as claimed in  claim 11 , wherein the catalyst contains Sn.  
   
   
       20 . A process as claimed in  claim 11 , wherein the Ni:Sn molar ratio exceeds 1:1.  
   
   
       21 . A process as claimed in  claim 11 , which method includes using silica-alumina as the support for the catalyst.  
   
   
       22 . A catalyst for use in a method for reducing methane formation when hydrocracking hydrocarbons, said catalyst being non-sulfided and containing Ni and silica, wherein the Ni content is at least 1 mass % and the silica content is at least 20 mass % and the silica is present in the form of silica-alumina.  
   
   
       23 . A catalyst as claimed in  claim 22 , which has a Ni content of at least 3 mass %.  
   
   
       24 . A catalyst as claimed in  claim 22 , which has a Ni content of at least 4.5 mass %.  
   
   
       25 . A catalyst as claimed in  claim 22 , which has at least 40 mass % silica.  
   
   
       26 . A catalyst as claimed in  claim 22 , which catalyst contains Sn.  
   
   
       27 . A catalyst as claimed in  claim 22 , wherein the Ni:Sn molar ratio exceeds 1:1.  
   
   
       28 . A catalyst as claimed in  claim 22 , which method includes using silica-alumina as the support for the catalyst.
