The present disclosure relates generally to processes for separating chemical compounds via two-dimensional gas chromatography. Certain embodiments comprise rapid heating and cooling of the second dimension column by a unique arrangement of heating and cooling elements.

Gas chromatography temperature modulation

The present disclosure relates generally to systems for separating chemical compounds via two-dimensional gas chromatography. Certain embodiments of the system are configured to rapidly heat and cool the second dimension column by a unique arrangement of heating and cooling elements.

System for gas chromatography temperature modulation

Attrition resistant, sorbent compositions for the removal of elemental sulfur and sulfur compounds, such as hydrogen sulfide and organic sulfides, from cracked-gasoline and diesel fuels are prepared by the impregnation of a sorbent support comprising zinc oxide, expanded perlite, and alumina with a promoter such as nickel, nickel oxide or a precursor of nickel oxide followed by reduction of the valence of the promoter metal in the resulting promoter metal sorbent support composition. Also disclosed is a composition comprising desulfurized, cracked-gasoline wherein the desulfurized cracked-gasoline comprises less than about 1 ppmw thiol compounds and less than about 1 ppmw tetrahydrothiophene compounds.
