摘要： A method is disclosed for synthesizing a reactive sulfur-containing adsorbent material for removing metals, preferably mercury, from hydrocarbon fluids. The method includes impregnating a porous polystyrene resin with elemental sulfur, and heating the impregnated resin/sulfur mixture to chemically fix the sulfur to the resin. The elemental sulfur may be in solid, liquid, or vapor phase under conditions of contact with the resin. Also disclosed is the reactive adsorbent synthesized by this method. Also, a process is disclosed for removing mercury from hydrocarbon fluids by using a reactive adsorbent of the invention.

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： The invention is concerned with a process for removing mercury from a non-polar organic medium like a liquid hydrocarbon mixture, most preferably a natural gas condensate, by contacting the medium to be treated with a solid adsorbent, preferably an ion-exchange resin, containing active thiol-groups. By this method it is possible to remove mercury from the treated medium in an amount of more than 97%.

摘要： Cyclohexene can be advantageously separated from a mixture containing as main components benzene, cyclohexene and cyclohexane by a process wherein said mixture is brought into contact with a type X aluminosilicate zeolite, which has been ion-exchanged with a silver ion, as an adsorbent, whereby cyclohexene is selectively adsorbed thereon, and then, cyclohexene is desorbed therefrom. The desorption of cyclohexene is preferably carried out by using a desorbent, such as an alkylbenzene having 7 or 8 carbon atoms in the molecule.

摘要： THIS INVENTION RELATES TO A SYSTEM FOR ABATEMENT OF AIR POLLUTION AS CAUSED BY LEAD COMPOUNDS IN THE FUELS OF INTERNAL COMBUSTION ENGINES. IN ANOTHER ASPECT, IT RELATES TO SELECTTIVELY REMOVING ORGANOALKYL LEAD COMPOUNDS RESIDUALLY PRESENT IN FUELS PRIOR TO THEIR CARBURETION BY I.C. ENGINES SO AS TO MINIMIZE INTERFERENCE WITH CATALYTIC MUFFLER PERFORMANCE.

摘要： A NOVEL USE FOR SORBENTS INVOLVING THE SELECTIVE REMOVAL OF HEAVY METALS FROM LIQUID STREAMS HAS BEEN DISCOVERED MORE SPECIFICALLY IT HAS BEEN DISCOVERED THAT THESE SORBENTS SELECTIVELY REMOVE ALKYLL LEAD MOIETIES FROM GASOLINE. THE SORBENTS ARE COMPRISED OF METAL HALIDES (PREFERABLY TIN TETRACHLORIDE OR ANTIMONY PENTACHLORIDE) BONDED TO A SUITABLE SUBSTRATE THROUGH TERTIARY AMINE OR ALKYL HALIDE FUNCTIONAL GROUPS. THE SORBENDS CAN BE EFFECTIVELY REGENERATED.
