Abstract: Methods and compositions for stabilizing the activity of catalytic compositions during catalytic processes, such as alkylation. A catalytic composition comprising a partially deactivated ionic liquid catalyst may be regenerated by reaction with a metal to form reactivated catalyst and an inorganic catalyst precursor; and the catalytic composition may be amended in-process by addition of an organic catalyst precursor for reaction with the inorganic catalyst precursor to form fresh ionic liquid catalyst. The organic catalyst precursor may be protected from water, e.g., during handling, by hydrophobic material(s).

Abstract: A process for preparing a C4- product stream and a C6+ product stream is disclosed. The process involves contacting a C5 containing paraffinic feedstock with a catalyst that includes a hydrogenation/dehydrogenation catalyst and an olefin metathesis catalyst under conditions which dehydrogenate the paraffins to olefins. The olefins are then metathesized and rehydrogenated to provide a product stream. A C4- fraction and a C6+ fraction can each be isolated from the product stream. The C4- fraction can be used, for example, in an alkylation reaction to provide compounds useful in gasoline compositions. Unconverted C5 paraffins can be recycled. The C6+ fraction can be used, for example, as solvents. Alternatively, they can be isomerized to form gasoline additives, or can be converted to aromatic compounds via reforming, for example, using conventional reforming techniques, preferably using the AROMAX™ process or traditional rheniforming conditions.
