Abstract
Composite catalytic products composed of a metal chelate based catalyst on a solid adsorbent support for use in fixed-bed processes for sweetening mercaptans contained in petroleum fractions are disclosed. The composites contain from 0.05 to 5 weight percent of a metal chelate, from 5 to 15 weight percent of pyrolyzed carbon and from 60 to 90 weight percent of a mineral matrix. The support material is obtained by pyrolysis of wash concentrates of raw wools.
