A process to rejuvenate a spent sorbent to produce a rejuvenated sorbent is provided. This process comprises: (a) contacting a spent sorbent with a zinc composition that comprises zinc oxide, or a precursor to zinc oxide, to form a contacted composition; (b) drying said contacted composition at a temperature in the range of about 25 DEG C. to about 375 DEG C. for a time period in the range of about 1 minute to about 24 hours, to form a dried, contacted composition; and (c) calcining said dried, contacted composition at a temperature in the range of about 400 DEG C. to about 800 DEG C. for a time period in the range of about 1 minute to about 24 hours, to form said rejuvenated sorbent.
