Abstract: PROBLEM TO BE SOLVED: To provide a denitification and hydrogenating ring-opening reaction of a polycyclic aromatic compound, by using a phosphoric acid-loaded metal oxide catalyst. SOLUTION: This method for performing a denitrification and a hydrogenating ring-opening reaction of a polycyclic aromatic compound, is to perform a hydrogenation, a hetero atom removal and an aromatic ring-opening reaction of a polycyclic aromatic compound such as a liquefied coal oil, a heavy crude petroleum, etc., by using a phosphoric acid-loaded metal oxide catalyst. A method of direct liquefaction of coal, is to produce a high quality liquefied product by directly hydrogenating the aromatic compounds of the coal in low temperature reaction range of 350-430 deg.C by using the phosphoric acid-loaded metal oxide catalyst. The phosphoric acid-loaded metal oxide catalyst is a phosphoric acid-loaded manganese oxide/nickel oxide catalyst.

Abstract: PURPOSE: To efficiently and economically liquefy coal, by using a specific supported iron-based catalyst capable of reducing an amount of a catalyst added and advancing activation of coal itself without requiring addition of sulfur having troubles in treatment after reaction. CONSTITUTION: Coal is liquefied by using a supported type iron catalyst such as a supported sulfate type iron catalyst obtained by impregnating coal with ferric sulfate, neutralizing ferric sulfate with ammonia generated by urea decomposition in an aqueous solution to form a sulfate type iron catalyst and supporting the catalyst on coal. For example, pulverized coal is mixed with an aqueous solution having dissolved ferric sulfate and urea and the stirred coal is impregnated with ferric sulfate and heated to 96-98 deg.C. Urea in the aqueous solution is decomposed, ammonia is generated, ferric sulfate is neutralized to form sulfate type iron catalyst, which is supported on coal to give a sulfate type iron catalyst. By using this catalyst and tetralin as a circulating solvent, coal is liquefied under 100-300 atmospheric pressure and charging H2 gas to reaction system.

Abstract: PURPOSE:To streamline and promote coal liquefaction reaction by drawing out the gas phase within the reaction vessel besides the coal liquefaction product and condensing the same. CONSTITUTION:A preheated coal slurry in a paste form consisting of pulverized coal and an org. solvent is fed through a high pressure paste pump 1 and lines 14 and 16 into a reaction vessel 4, where it is reacted with the recycle gas circulated from a gas liq. separator 7 through a line 17 and a compressor 3 and pressurized hydrogen supplied from a compressor 2, thereby effecting liquefaction of the coal. The coal liquefaction product is transferred through a line 18 to the gas liq. separator 7. A vale 8 is opened, and hydrogen is pressed by means of the compressor 2 into a condenser 6 having a buffle plate 23, thereby causing the pressure of the condenser to reach a pressure higher by 5-10kg/cm than that of the reaction vessel 4. A valve 9 is opened and the liq. within a line 26, and a high-temp. separator 5 is discharged on the side of the reaction vessel 4. A valve 10 is opened, and the gas phase component within the reaction vessel 4 is introduced through the separator 5 and lines 26 and 27 into the condenser 6, thereby effecting condensation of the gas phase component.

Abstract: PROBLEM TO BE SOLVED: To liquefy coal efficiently by a ruthenium carrying metal oxide catalyst. SOLUTION: This method comprises directly hydrogenating aromatic nuclei of coal in the presence of a ruthenium-carrying metal oxide catalyst having the activity of selectively hydrogenating aromatic nuclei in a reaction zone at a temperature as low as 350-425 deg.C to produce a high-quality liquid product. The metal oxide is a compound double oxide comprising oxides of nickel, manganese, zinc and/or lanthanum. This catalyst has an excellent activity of nucleus hydrogenation under the conditions of direct liquefaction reaction. In a reaction zone at a temperature as low as 375-400 deg.C, the yields of products having a high depth of hydrogenation can be attained. A ruthenium-carrying metal oxide catalyst having a high activity of highly selective nucleus hydrogenation is provided.

Abstract: PURPOSE:To effectively and selectively extract and separate polar compounds such as phenols and nitrogen compounds by hydrogenating a fossil fuel such as coal or petroleum and mixing the obtained naphtha distillate with an aqueous solution of an anionic surfactant. CONSTITUTION:A fossil fuel such as coal, petroleum or tar sand bitumen is hydrogenated in a bench scale liquefaction plant and subsequently distilled. The obtained naphtha fraction is mixed with the aqueous solution of an anionic surfactant such as a sodium alkylbenzene sulfonate to readily, efficiently and selectively extract and separate polar compounds such as phenol compounds and nitrogen compounds.

Abstract: PURPOSE:To directly determine trace oxygen by thermally cracking a sample, bringing the thermally cracked gas into contact reaction with carbon to form a gas contg. carbon monoxide, separating the carbon monoxide from the formed gas, bringing the carbon monoxide into reaction with hydrogen to form methane and using the methane in a hydrogen flame ionizer, then making determination. CONSTITUTION:A thermally cracking section 1 and CO converter section 2 of the apparatus for analyzing trace oxygen are formed in the same reaction vessel and a sample injecting port 7 is added to the top end of the reaction tube. A thermal conductivity detector 4 is attached behind the formed gas separating section 3 of the apparatus. High-purity gaseous helium is branched to two systems as a carrier gas at the time of analyzing the gaseous sample with this apparatus. One of these gases is introduced to a reference side of a TCD and the other one is introduced to the thermally cracking section 1 side and is passed in the apparatus system until finally the gas is introduced to a detecting section 6. Various gases are formed by thermal cracking and the soln. sample is introduced from the sample injecting port 7 into the thermally cracking section1 by using a microsyringe. The thermally cracked gas is introduced into the converter section 2.
