    摘要： 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.

    摘要： A catalytic reaction process which involves exposing a hydrocarbon feed including nitrogenous contaminants as well as dialkyl sulfides to a material capable of adsorbing the nitrogenous contaminants as well as dialkyl sulfides from the feed before introducing the stream substantially devoid of nitrogenous contaminants and dimethyl sulfide into a feed zone of a reactor; contacting the hydrocarbon stream with a catalyst material in the reaction zone; and catalytically reacting the hydrocarbon stream under conditions which favor forming a reaction product and inhibiting reaction of nitrogenous contaminants and dimethyl sulfide with the catalyst material.

    摘要： A process for separating a C.sub.10 aromatic isomer, particularly paradiethylbenzene, from a feedstream containing a mixture of C.sub.10 aromatic isomers by contacting the feedstream with a bed of the adsorbent zeolite beta. The adsorbed C.sub.10 aromatic isomer is removed from the adsorbent by desorption.
