International Classification:

B01D 1100

US Classification:

210638, 210639, 210763, 210806, 208234, 208218

Abstract:

The invention relates to a method for treating naphtha, such as catalytically cracked naphtha, in order to remove acidic impurities, such as mercaptans. In particular, the invention relates to a method for mercaptans having a molecular weight of about C (C H S=90 g/mole) and higher, such as recombinant mercaptans.

US Classification:

208203, 208212, 208226, 208228, 208229, 208230, 208235

Abstract:

The invention relates to a method for desulfurizing naphtha boiling-range hydrocarbons such as cracked naphtha. More particularly, the invention relates to hydrotreating the naphtha under selective hydrotreating conditions, and then removing mercaptans from the hydrotreater effluent using a caustic extractant.

Abstract:

The invention relates to a method for treating and upgrading a hydrocarbon containing acidic species such as mercaptans, comprising:(a) contacting the hydrocarbon, in the essential absence of oxygen, with a first phase of a treatment composition containing water, dissolved alkali metal hydroxide, cobalt phthalocyanine sulfonate, and dissolved alkylphenylates and having at least two phases, (i) the first phase containing water, alkali metal alkylphenylate, dissolved alkali metal hydroxide, and dissolved sulfonated cobalt phthalocyanine, and (ii) the second phase containing water and dissolved alkali metal hydroxide; and then (b) separating an upgraded hydrocarbon.
