SELECTIVE ADSORBENT MATERIAL OF SULFUR AND/OR NITROGEN-CONTAINING COMPOUNDS IN FRACTIONS OF OIL HYDROCARBONS AND APPLICATION PROCESS THEREOF.

摘要

The present invention is related to a selective adsorption process of nitrogen and sulfur compounds contained in different fractions of oil hydrocarbons. A solid material acts as an adsorbent, this latter element consisting in a single-structured material that presents the morphology of the nanofibers and/or nanotubes of an inorganic oxide of a Group IVB metal with a high specific area ranging from about 100 m2/g to about 600 m2/g. The adsorbent material of the present invention may include or not a transition metal, and may selectively adsorb compounds exclusively having nitrogen, or simultaneously adsorb compounds having both nitrogen and sulfur.
