Abstract: An improved catalyst activation process for olefinic naphtha hydrodesulfurization. This process maintains the sulfur removal activity of the catalyst while reducing the olefin saturation activity.

Abstract: A process for hydrofining a lubricating oil feedstock comprising contacting the feedstock with a hydrofining catalyst in a hydrofining zone under hydrofining conditions wherein the hydrofining catalyst comprises a bulk metal catalyst containing non-noble Group VIII metal molybdate in which at least a portion but less than all of the molybdenum is replaced by tungsten.

Abstract: A process for upgrading a wax-containing feedstock to produce a wax and a high VI/low volatility lubricating oil basestock. The process comprises subjecting the raffinate from a solvent extraction step to a two step, single stage hydroconversion process wherein the first step involves severe hydroconversion of the raffinate followed by a cold hydrofinishing step.

Abstract: The invention relates to a method for determining total reactive sulfur in a crude oil or fraction thereof using a mass spectrometer or gas chromatograph and mass spectrometer. Selecting fragment ions characteristic of reactive sulfur species enables the quantitative determination of total reactive sulfur species. The use of a low resolution mass spectrometer allows the rapid determination of total reactive sulfur in field or remote locations where more sophisticated instruments are not available.

Abstract: A process for selectively removing lower molecular weight naphthenic acids from an acidic crude by treating the crude with a small pore hydrotreating catalyst at temperatures of from about 200.degree. to 370.degree. C. Removing these lower molecular weight naphthenic acids reduces the corrosive nature of acidic crudes.

Abstract: A lubricant oil composition useful for reducing friction in an internal combustion engine which comprises a lubricating oil basestock and an alkoxylated amine salt of hydrocarbylsalicylic acid, said salt have the formula ##STR1## where R is a hydrocarbyl group having from 2 to 22 carbon atoms, R.sup.1 is a hydrocarbyl having from 2 to 30 carbon atoms, and x and y are each independently integers of from 1 to 15 with the proviso that the sum of x+y is from 2 to 20.

Abstract: A new group of materials comprises intercalates of organometallic compounds in layered structures of metal chalcogenohalides. The organometallic intercalates are represented by the general formula MX.sub.a Y.sub.b [Z].sub.c, where M is at least one metal selected from the group consisting of titanium, vanadium, chromium, manganese, iron and indium, X and Y are members of the group consisting of chalcogenides and halides, "a" and "b" each range from 0 to 2, with the sum of "a" and "b" being substantially equal to about 2, Z is an organometallic "sandwich" compound with parallel carbocyclic rings and a first ionization potential less than about 7 eV and "c" ranges from about 0.1 to 0.2.
