Our zeolite material, a synthetic absorbent that is selective for Benzene, Toluene, Ethylbenzene and Xylene (BTEX compounds) will hold benzene equivalent to 14% of its weight, and can be used in flow-through systems similar to those used for activated carbon. Thermal regeneration is possible for up to four cycles, and (unlike activated carbon) the regenerated material has the same capacity as virgin material. This material makes possible the treatment of large volumes of liquid to low BTEX concentrations without removing less regulated hydrocarbons to the same low concentrations.

This same synthetic absorbent is also effective (and selective) in removing BTEX compounds from air (or other gases) in the same type of apparatus in which activated carbon is used for this function.

Other synthetic zeolites are available for removal of benzene from hydrocarbon mixtures, for removal of PCB from hydrocarbon mixtures and for removal of various elements (such as: selenium, cadmium, chromium, mercury, lead, nickel and zinc) from water.
