The present invention relates to a process for reducing the acidity of a petroleum oil containing organic acids comprising treating said petroleum oil containing organic acids with an effective amount of an alcohol at a temperature and under conditions sufficient to form the corresponding ester of said alcohol.

Esterification of acidic crudes

The invention relates to a process for enhancing demetallation of metals containing hydrocarbonaceous feedstocks by contacting a metals containing hydrocarbonaceous feedstock at a sufficient temperature and pressure with an additive containing a polyoxyalkylene moiety said additive having preferential insolubility in alkane deasphalting solvent to produce an additive treated feedstock; and then contacting the resulting product with an effective deasphalting solvent to produce a deasphalted oil having a decreased metals content and an insoluble metals containing phase.

Additive enhanced solvent deasphalting process (law759)

The present invention is a process to remove a &plus;2 ionic charged, organically bound metal from a petroleum feed. The process includes contacting feed with aqueous carbon dioxide in the essential absence for emulsion formation.

Co2 treatment to remove organically bound metal ions from crude

Compositions useful in separating molecules or catalytic conversions comprise a substrate, a zeolite or zeolite-like layer, a selectivity enhancing coating in contact with the zeolite layer and optionally a permeable intermediate layer in contact with the substrate the zeolite layer being in contact either with the substrate or the optional intermediate layer.

Zeolite containing composition with a selectivity enhancing coating

The instant invention is directed to a process for extracting organic acids including naphthenic acids, heavy metals, and sulfur from a starting crude oil comprising the steps of:

Removal of naphthenic acids in crude oils and distillates

The present invention relates to a process for reducing the acidity of a petroleum oil containing organic acids comprising treating said petroleum oil containing organic acids with an effective amount of an alcohol at a temperature and under conditions sufficient to form the corresponding ester of said alcohol and wherein said treatment is conducted in the presence of a metal carboxylate.

Metal compounds as accelerators for petroleum acid esterification

Membranes useful in separating moleculres or catalytic conversions comprise a substrate, a zeolite or zeolite-like layer, a selectivity enhancing coating in contact with the zeolite layer and optionally a permeable intermediate layer in contact with the substrate the zeolite layer being in contact either with the substrate or the optional intermediate layer.

Zeolite membrane with a selectivity enhancing coating

A process for providing distillate products which are substantially sulfur free, which process comprises subjecting a distillate stream to conventional hydrodesulfurization conditions including a catalyst comprised of a Group VI metal and at least one Group VIII metal on a refractory support. The hydrodesulfurized stream is then treated with a solid adsorbent material capable of adsorbing beta and di-beta-substituted dibenzothiophene sulfur compounds.
