ABSTRACT:
Disclosed herein is a process for removing contaminating mercury from hydrocarbon streams, gas or liquid, wherein the stream is contacted with a molecular sieve pretreated with an alkali polysulfide. The pretreatment consists of saturating the sieve with an aqueous solution of the polysulfide and subsequently drying the saturated sieve under conditions calculated to dry but not decompose the polysulfide present.
