METHODS FOR UPGRADING OF CONTAMINATED HYDROCARBON STREAMS

AUTERRA, INC., Schenecta...

1. A method of upgrading an oxidized-heteroatom-containing hydrocarbon feed by removing oxidized-heteroatom contaminants,
the method comprising:
contacting one of sulfoxide, sulfone, sulfonate, and sulfonic acid, and combinations thereof in the oxidized-heteroatom-containing
hydrocarbon feed with a second feed comprising at least one caustic and at least one selectivity promoter to form a first
intermediate stream; and

removing the oxidized heteroatom contaminants from the first intermediate stream.

REACTION SYSTEM, METHODS AND PRODUCTS THEREFROM

AUTERRA, INC., Schenecta...

1. A method for reducing heteroatom content of a hydrocarbon feed comprising the steps of:
oxidizing the hydrocarbon feed to an oxidized heteroatom-containing hydrocarbon feed;
contacting the oxidized heteroatom-containing hydrocarbon feed with a caustic treatment solution comprising a phenol-derived
catalyst, a caustic and a selectivity promoter;

producing from said contacting step, a hydrocarbon product having a heteroatom content that is less than the heteroatom content
of the oxidized heteroatom-containing hydrocarbon feed.

ADSORBENTS AND METHODS OF USE

AUTERRA, INC., Schenecta...

1. A method for reducing a heteroatom content of a hydrocarbon feed comprising the steps of:providing an adsorbent having a metal complex bound to an inorganic oxide support, wherein the metal complex is a titanyl having a titanium molecule covalently bonded to an alcohol or polyol;
contacting the adsorbent with a hydroperoxide or a peracid, forming an activated adsorbent;
contacting the activated adsorbent with the hydrocarbon feed;
binding a heteroatom present in the hydrocarbon feed to the activated adsorbent, forming a heteroatom-bound adsorbent, leaving behind a hydrocarbon feed having a reduced heteroatom content; and
separating the hydrocarbon feed having the reduced heteroatom content from the heteroatom-bound adsorbent.
