Method for removing compounds containing sulfur from fuels

Abstract

The present invention relates to a process for removing sulfur-comprising compounds from fuels, wherein a sulfur-comprising fuel is brought into contact with copper-1,3,5-benzenetricarboxylic acid MOF.

1 . A process for removing at least one sulfur-comprising compound from at least one fuel, the process comprising:
 bringing the at least one sulfur-comprising fuel into contact with copper-1,3,5-benzenetricarboxylic acid MOF.   
     
     
         2 . The process according to  claim 1 , wherein the copper-1,3,5-benzenetricarboxylic acid MOF is present in a concentration of from 5 mg/ml to 100 mg/ml. 
     
     
         3 . The process according to  claim 1 , wherein a sulfur content of the at least one fuel is reduced to from 2 mg/kg to 10 mg/kg. 
     
     
         4 . The process according to  claim 1 , wherein sulfur uptake by the copper-1,3,5-benzenetricarboxylic acid MOF is at least 0.2 mg/g. 
     
     
         5 . The process according to  claim 1 , wherein a sulfur content of at least one previously sulfur-reduced fuel having an initial sulfur content of from 8 to 15 mg/kg is reduced by at least a further 10%. 
     
     
         6 . The process according to  claim 1 , wherein an uptake of sulfur is concluded within a reaction time of from 5 minutes to 60 minutes. 
     
     
         7 . The process according to  claim 1 , carried out at ambient temperature and ambient pressure on board a mobile system. 
     
     
         8 . The process according to  claim 1 , wherein the at least one fuel is selected from the group consisting of petrol, diesel, heating oil, kerosene, and methanol. 
     
     
         9 . The process according to  claim 1 , wherein copper-1,3,5-benzenetricarboxylic acid MOF is structurally integrated into a fuel filter or into a vehicle tank of a mobile system or is a separate device which can be introduced before filling of the tank. 
     
     
         10 . The process according to  claim 1 , carried out continuously. 
     
     
         11 . The process according to  claim 1 , wherein a low-sulfur fuel obtained is employed in desulfating of an exhaust gas after-treatment system of an engine or as reducing agent for deNOx catalysts in lean-burn exhaust gas. 
     
     
         12 . The process according to  claim 2 , wherein a sulfur content of the at least one fuel is reduced to from 2 mg/kg to 10 mg/kg. 
     
     
         13 . The process according to  claim 2 , wherein sulfur uptake by the copper-1,3,5-benzenetricarboxylic acid MOF is at least 0.2 mg/g. 
     
     
         14 . The process according to  claim 3 , wherein sulfur uptake by the copper-1,3,5-benzenetricarboxylic acid MOF is at least 0.2 mg/g. 
     
     
         15 . The process according to  claim 2 , wherein a sulfur content of at least one previously sulfur-reduced fuel having an initial sulfur content of from 8 to 15 mg/kg is reduced by at least a further 10%. 
     
     
         16 . The process according to  claim 3 , wherein a sulfur content of at least one previously sulfur-reduced fuel having an initial sulfur content of from 8 to 15 mg/kg is reduced by at least a further 10%. 
     
     
         17 . The process according to  claim 4 , wherein a sulfur content of at least one previously sulfur-reduced fuel having an initial sulfur content of from 8 to 15 mg/kg is reduced by at least a further 10%. 
     
     
         18 . The process according to  claim 2 , wherein an uptake of sulfur is concluded within a reaction time of from 5 minutes to 60 minutes. 
     
     
         19 . The process according to  claim 3 , wherein an uptake of sulfur is concluded within a reaction time of from 5 minutes to 60 minutes. 
     
     
         20 . The process according to  claim 12 , wherein an uptake of sulfur is concluded within a reaction time of from 5 minutes to 60 minutes.
