| titleOfInvention | Treated pillared clays and alkylation process using same |
| abstract | This invention relates to a treated pillared clay made by the process comprising the steps of:n (A) contacting at least one clay with an effective amount of at least one ammonium ion source to exchange sodium and/or calcium ions in said clay for ammonium ions to provide an ammonium-containing clay, said clay comprising metal oxides and hydroxides and having a lamellar structure with lamellar layers and interlamellar spaces disposed between the lamellar layers and exchangeable sodium and/or calcium ions occupying said interlamellar spaces; (B) contacting said ammonium-containing clay with an effective amount of at least one source of fluorine to replace at least part of the hydroxyl groups in said clay with fluorine to provide a fluorine- and ammonium-containing clay; (C) contacting said fluorine- and ammonium-containing clay with an effective amount of at least one pillaring agent to form a fluorine-containing pillared clay; and (D) contacting said fluorine-containing pillared clay with an effective amount of at least one inorganic acid to impregnate and/or incorporate at least part of said acid on said clay. n This invention also relates to a process for making the foregoing treated pillared clays. This invention also relates to the use of these treated pillared clays as alkylation catalysts. |
