Abstract: The present invention relates to poly α-olefins (PAO's) which exhibit superior Noack volatility at low pour points. Mixtures of 1-decene and 1-dodecene are polymerized using an alcohol promoted BF3 in conjunction with a combination of cocatalysts. The reaction mixture is distilled to remove the unreacted monomeric and dimeric species. The resulting product is then hydrogenated to saturate the oliogomers to provide a hydrogenated product which has a viscosity of 5 cSt. This product is distilled to provide PAO's of varying viscosity grades. The 4 cSt PAO is comprised mostly of trimers and tetramers while the 6 cSt product is comprised of trimers, tetramers, and pentamers.

Abstract: Heavy crude oils which contain metal contaminants such as nickel, vanadium and iron may be separated from light hydrocarbon oils by passing a solution of the crude oil dissolved in a cycloparaffinic hydrocarbon solvent containing from about 5 to about 8 carbon atoms by passing through a polymeric membrane which is capable of maintaining its integrity in the presence of hydrocarbon compounds. The light hydrocarbon oils which possess relatively low molecular weights will be recovered as the permeate while the heavy oils which possess relatively high molecular weights as well as the metal contaminants will be recovered as the retentate.

Abstract: Used oil is rerefined by distillation and extraction with tetrahydrofurfuryl alcohol. In accordance with the process, used oil is rerefined by distillation to remove a volatile forecut followed by further distillation with recirculation provisions to obtain the desired fractions of lubricating oil products while reducing the vaporization temperature of the oil. The recycle effect tends to reduce coking and cracking while providing a greater recovery of lubricating oil products through the carrier effect of the light ends. After the desired fractions of lubricating oil have been obtained by the distillation phase of the process, tetrahydrofurfuryl alcohol is utilized in an extraction process to remove impurities remaining in the distilled oil. The tetrahydrofurfuryl alcohol-lube oil mixture is separated into a raffinate and extract stream for distilling and steam stripping the tetrahydrofurfuryl alcohol therefrom.In one embodiment of the invention, a waste oil feedstock has water, gasoline and other similarly volatile components removed in a first stage evaporator (16). Heavier fuel, such as fuel oil is then removed in the second stage evaporator (28). A light lube oil fraction is then obtained by distillation with a third stage wiped-film evaporator (40). Finally, a heavy lube oil fraction is obtained by distillation of the bottoms from the evaporator (40) in a fourth-stage with a wiped-film evaporator (64). The heavy and light lube oil fractions are then treated in the fifth stage of the process in which each of the lube oil fractions mix with tetrahydrofurfuryl alcohol in extraction columns (80) and (96). Each of the tetrahydrofurfuryl alcohol and oil fractions are then separated into raffinate and extract streams for further treatment to further separate and recover the finished light and heavy lube oil products and tetrahydrofurfuryl alcohol which is reused in the fifth stage of the process.

Abstract: A method for the continuous decomposition of stable carbon dispersions in waste engine oils, the decomposition being immediately followed by an oil re-refining step as, preferably, a short-path distillation. In accordance with the invention, waste oil is heated, under a pressure ranging from 1 to 100 Pa, in the form of a thin film (0.1 to 2 mm thickness) to a temperature of 200.degree.-300.degree. C., whereby liberated vapors together with entrained microdrops condense at a temperature of 20.degree.-100.degree. C. Thereupon the condensate is immediately subjected to a short-path distillation to be re-refined. The entire process is advantageously effected in a single apparatus.
