A method of denitrogenating an oil containing a relatively high concentration of nitrogenous compounds characterized by, first, extracting the nitrogenous compounds from the oil with an operable acid solvent to produce a raffinate of low nitrogen content oil and a bottoms of high nitrogen content oil; then recovering the acid solvent from the bottoms, simultaneously producing a small volumeteric flow rate stream of oil containing high content of nitrogenous compounds; depending upon the volumeteric rate of the high nitrogen content oil stream and upon demand, sending it to a hydrogen producing plant for supplying hydrogen for hydrogenation; and recycling the acid solvent. Preferred acid solvents comprise phosphoric acid, formic acid or the monoammonium salt of phosphoric acid. The recovery of the solvent may be by neutralization or by distillation. Also disclosed are complete process steps including an initial hydrogenation step before the extraction; the washing of the oil streams before they are sent to their destinations; and hydrodenitrogenation of the low nitrogen raffinate oil.

This invention concerns an efficient, high recovery, single product, multiple-stage process for producing high BTU methane from a low BTU feed gas containing carbon monoxide, hydrogen, nitrogen and other materials. In the process, impurities like hydrogen sulfide and carbon dioxide are removed at the appropriate point. The carbon monoxide is removed and split into two streams. One stream is reacted with steam to provide additional hydrogen which is mixed with the other carbon monoxide stream and passed to a methanator. The hydrogen in the feed gas is recovered in an especially efficient two stage manner which is suitable for use with standard cooling water and which reduces metallurgical problems, compression requirements and heat requirements. In the first stage, metal hydrides are formed, thereby separating the hydrogen in the feed gas from nitrogen and the nitrogen exits and is removed. The hydrides are then decomposed to generate additional hydrogen which is also passed to the methanator where carbon monoxide and hydrogen are reacted to form methane and water.

A method for generating heat from retorted oil shale particles which are carrying a deposit of carbon wherein the particles are lifted upwardly in a heating chamber using a carrier gas and the carrier gas is controlled in relation to the particles so that at any given time during the lifting step a substantial amount of the particles fall downwardly for a finite distance thereby causing internal backmixing of the heated falling particles with relatively cooler rising particles.

Low BTU feed gas formed by gasification of carbonaceous materials with air is converted to high BTU gas by partial carbon monoxide separation and by using the reducing characteristic of the remaining feed gas in the iron reduction unit of a standard iron-steam process for manufacturing hydrogen. The hydrogen manufacturing stage also removes nitrogen which is a primary cause of low heat value in upgraded gases. The separated CO and the manufactured H. sub. 2 are converted to a high quality methane. In the process, other undesirable impurities and diluents like hydrogen sulfide and carbon dioxide may be removed first.

The thermal cracking of retort oil vapors in an elongated reactor is improved by passing the effluent oil vapors and gases from a retort to a thermal cracking unit before the temperature of the retort effluent falls below 680. degree. F. This encourages the more desirable cracking reactions, increases the thermal efficiency of the process, and avoids preheater coking.

A method for removing nitrogen from an essentially liquid syncrude feed obtained from at least one of oil shale, tar sands, and coal wherein the syncrude is mixed with an acid selected from the group consisting of sulfuric, phosphoric, hydrochloric, and combinations thereof, settling to form a first phase composed of syncrude low in nitrogen and a second phase composed of acid and syncrude high in nitrogen, separating the two phases, and catalytically hydrotreating the high nitrogen phase to reduce its nitrogen content.

A method for reducing the nitrogen content of a syncrude feed obtained from at least one of oil shale, tar sands, and coal wherein the syncrude is mixed with an extractant-catalyst which is effective for extracting nitrogen materials from the syncrude feed and also effective as a hydrocracking catalyst for said syncrude feed. Said mixing helps form a first phase composed of a first low nitrogen syncrude product and a second phase composed of said extractant-catalyst and high nitrogen syncrude feed, separating said first and second phases from one another, and hydrocracking said second phase to produce a second low nitrogen syncrude product.
