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).
