Abstract
The present invention is directed to the removal of organochlorides from hydrocarbon streams using highly crystalline molecular sieve material, such as zeolites, and particularly zeolite X in a sodium form, and the removal of organochlorides from hydrocarbon streams containing olefinic compounds using such molecular sieves in combination with alumina for the purpose of effecting a decomposition of the organochloride into a corresponding unsaturated hydrocarbon molecule and a molecule of hydrocarbon chloride wherein the hydrocarbon chloride is removed from the hydrocarbon stream by being adsorbed onto the adsorbent of the highly crystalline molecular sieve used alone, or in combination with alumina in those instances where olefinic compounds are present in the hydrocarbon stream, so that the unsaturated hydrocarbon molecule may be recovered from the resultant hydrocarbon stream containing a reduced amount of organochlorides.
