Method of preparation of silica supported perfluoroalkylsulfonic acid catalyst system |
摘要 |
<p>A method of preparing a catalyst system which comprises mixing a first solid material comprising at least one perfluoroalkylsulfonic acid salt with a second solid material comprising at least one silanol comprising hydroxy groups and silicon to form a gel comprising silica and the at least one perfluororalkylsulfonic acid salt, and contacting the gel with an acidic solution to convert at least a portion of the at least one perfluoroalkylsulfonic acid salt to at least one perfluoroalkylsulfonic acid is disclosed. Alternatively, a method of preparing a catalyst system which comprises mixing at least one perfluoroalkylsulfonic acid salt with silica gel to form a gel comprising silica and at least one perfluororalkylsulfonic acid salt, and contacting the gel with an acidic solution to convert at least a portion of the at least one perfluororalkylsulfonic acid salt to at least one perfluororalkylsulfonic acid is disclosed. The thus-obtained catalyst systems are employed as catalysts in the oligomerization of a hydrocarbon feedstock comprising unsaturated hydrocarbons.</p> |
