Abstract
Compositions and processes are disclosed for removing sulfur and sulfur compounds from hydrocarbon fuel feedstocks. The feedstock is contacted with a regenerable sorbent such as a compound of the formula TixCeyO2 where 0<x/y≦1 and where 0<x≦1 and 0<y≦1 capable of selectively adsorbing sulfur compounds present in the hydrocarbon feedstock at about 0° C. to about 100° C. such as at about 25° C.
Claims13
A method for removing sulfur compounds from a hydrocarbon fuel feedstock comprising,
- contacting the feedstock with a regenerable adsorbent material capable of selectively removing sulfur compounds present in the hydrocarbon feedstock wherein the contacting is performed at a temperature of about 0° C. to about 100° C. at a pressure of about 0.05 MPa to about 0.20 MPa and wherein the regenerable sorbent material comprises a compound of the formula TixCeyO2 where 0<x/y≦1 and where 0<x≦1 and 0<y≦1.
A compound suitable for selectively adsorbing sulfur compounds from a hydrocarbon fuel feedstock over a temperature range of about 0° C. to about 100° C. wherein the compound has the formula TixCeyO2 where 0<x/y≦1 and where 0<x≦1 and 0<y≦1.
A compound suitable for selectively adsorbing sulfur compounds from a hydrocarbon fuel feedstock over a temperature range of about 0° C. to about 100° C. wherein the compound comprises a compound of the formula MO—CeO2 where M is any of Ag, Au, Ba, Be, Ca, Co, Cr, Cu, Fe, Ge, Hf, Ir, La, Mg, Mo, Ni, Os, Pb, Pd, Pt, Rh, Ru, Sc, Sn, Sr, Ti, W, Y, Zr and mixtures thereof, wherein the compound of the formula MO—CeO2 is either Ti0.1Ce0.9O2 or W0.1Ce0.9O2.
