摘要： A process is disclosed for the removal of basic heterocyclic nitrogen compounds from a petroleum crude oil or fraction thereof which comprises treating, the petroleum crude oil in a distillation zone to form a distillation bottoms stream which is rich in basic heterocyclic nitrogen compounds. This stream is passed without cooling or heat removal to a two-phase extraction zone with an extractant consisting essentially of an aqueous solution of a lower carboxylic acid and preferably having from 1 to 15 carbon atoms. The extractant complexes the basic heterocyclic nitrogen compound to produce a stream of petroleum crude oil or fraction thereof having a smaller content of heterocyclic nitrogen compounds and a stream comprising the lower carboxylic acid extractant with an increased quantity of basic heterocyclic nitrogen compounds. Both of these streams are passed to distillation without heating. The stream of petroleum crude having the smaller content of heterocyclic nitorgen compound is distilled into an overhead stream and a bottoms stream, the latter of which is hydrotreated to the product of this invention. The stream comprising the higher nitrogen content is passed, without heating, to a distillation zone wherein a stream very high in nitrogen content is removed and an extractant recycle stream is recovered. The extractant recycle stream is then recycled to the extraction zone.

摘要： The instant invention discloses a method of removing heterocyclic basic nitrogen compounds from petroleum oils which comprises first enhancing the concentration of the heterocyclic basic nitrogen compounds in a portion of the petroleum oil and then extracting the enhanced portion of the heterocyclic basic nitrogen compounds with a two phase system having an aliphatic carboxylic acid as the extracting agent. In the hydrotreating embodiment of this invention a portion of all of the nitrogen compounds are converted to heterocyclic basic nitrogen compounds and thereby more feasibly extracted. In the distillation embodiment of this invention the nitrogen compounds are actually concentrated and thereby result in a more feasible extraction with the aliphatic carboxylic acid.

摘要： There is provided a process for reduction of the nitrogen content of shale oil. The process comprises contacting shale oil with a low acid strength solvent in a first extraction zone, followed by contacting the shale oil with a high acid strength solvent in a second extraction zone. A portion of the high acid strength solvent containing extracted nitrogen-containing and non-nitrogen-containing compounds is passed to the first extraction zone and diluted to form low acid strength solvent, and at least a portion of the non-nitrogen-containing compounds redissolve into the shale oil in contact with the low acid strength solvent and are recovered. Thus, oil recovery is maximized at high nitrogen removal.
