To provide a hydrocarbon reforming/trapping material which is capable of adsorbing and reforming a hydrocarbon. A hydrocarbon reforming/trapping material of the present invention has an SiO.sub.2/Al2O.sub.3 ratio of from 7 to 12, and contains an Fe(II)-substituted beta zeolite which is ion-exchanged by Fe(II) ions. The amount of supported Fe(II) is preferably 0.001-0.5 mmol/g with respect to the Fe(II)-substituted beta zeolite. This Fe(II)-substituted beta zeolite is suitably produced by dispersing and mixing a beta zeolite having an SiO.sub.2/Al.sub.2O.sub.3 ratio of from 7 to 12 in an aqueous solution of a water-soluble compound of divalent iron, and mixing and stirring the solution, so that Fe(II) ions are supported on the beta zeolite.

A process for removal of mercury in a gas dehydration system comprising (a) adding a complexing agent to a recirculated glycol solvent as part of the glycol solution feed prior to or at the dehydration liquid contactor and recirculating continuously with the glycol solvent, (b) selectively reacting the complexing agent with mercury in the wet natural gas to remove the mercury from the dry natural gas product, (c) and feeding the rich glycol with the complexing agent to a regenerator and continuously regenerating.

This disclosure relates to the adsorption and separation of carbon dioxide in a feed stream (e.g., natural gas) using zeolite ITQ-55 as the adsorbent. A process is disclosed for removing impurities such as carbon dioxide and nitrogen while producing a hydrocarbon product. The process involves passing a feed stream through a bed of an adsorbent comprising zeolite ITQ-55 to adsorb carbon dioxide from the feed stream, thereby producing a product stream depleted in carbon dioxide. The zeolite ITQ-55 has a mean crystal particle size within the range of from about 0.1 microns to about 100 microns. The feed stream is exposed to the zeolite ITQ-55 at effective conditions for performing a kinetic separation, in which the kinetic separation exhibits greater kinetic selectivity for carbon dioxide than for methane or nitrogen. The system and method of this disclosure are particularly suitable for use with feed streams in excess of 10 MMSCFD utilizing rapid cycle PSA operations by tuning crystals size.
