Composite adsorbents for purifying hydrocarbon streams

摘要

Solid adsorbents formed for the purification of hydrocarbons comprises: (1) an alumina; (2) a zeolite present in a quantity of at least 10% molar of the stoichiometric amount necessary to neutralize the negative charge on the zeolite lattice, expressed as oxide; and (3) a metallic constituent. Independent claims are also included for the following: (1) preparation of the composite adsorbents; and (2) process of eliminating contaminants in hydrocarbons.
