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： The invention disclosed is for a combination of two processes to enable the clean burning of coal in a coal water mixture. First the coal is ground and then treated with a desulfurizing microorganism to desulfurize the coal. After separation the coal is formulated into a coal water admixture in requisite quantities of water to coal, and with proper inclusion of additives, is combusted in a suitable furnace equipped with a means to burn a coal-water mixture. The desulfurized coal, after treatment with a select microorganism, will contain less than 1.0 wt % pyritic (inorganic) sulfur, be low in ash content and be cleanly combustible to capture its latent heat values.

摘要： A process is disclosed for the removal of basic heterocyclic nitrogen compounds from a petroleum crude oil or fraction thereof which comprises first treating the petroleum crude oil or fraction thereof rich in basic heterocyclic nitrogen compounds in a two-phase extraction zone with an extractant consisting essentially of an aqueous solution of a lower carboxylic acid, preferably having between 1 and 15 carbon atoms. The extractant complexes the basic heterocyclic nitrogen compounds 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. The petroleum crude oil or fraction thereof possessing a reduced quantity of heterocyclic nitrogen compounds is hydrotreated in the presence of hydrogen and a hydrotreating catalyst to further remove the basic heterocyclic nitrogen compounds. The extractant stream is treated in an extractant separation zone to renovate the extractant for recycle to the two-phase extractant zone, substantially free of removed basic heterocyclic nitrogen compounds.
