TL;DR: In this article, a process to prepare very low sulphur, very low aromatic hydrocarbon fluids having a boiling range in the range of from 100 to 400°C and not more than 80°C, comprising at least two successive steps of -deep hydrodesulphurating of middle distillate down to less than 10 ppm sulphur and -catalytic hydrogenating the desulphurized middle distillation of preceding step at a temperature from 80 to 180°C
Abstract: The invention provides a process to prepare very low sulphur, very low aromatic hydrocarbon fluids having a boiling range in the range of from 100 to 400°C and a boiling range of not more than 80°C, comprising at least the two successive steps of -deep hydrodesulphurating of middle distillate down to less than 10 ppm sulphur, and -catalytic hydrogenating the desulphurized middle distillates of preceding step at a temperature from 80 to 180°C and at a pressure from 60 to 160 bars.

TL;DR: In this paper, a method for simultaneously producing hydrogen and aromatic hydrocarbons including benzene and naphthalene without causing the detereoration of catalytic activity is proposed. But the method requires the feedstock lower hydrocarbon and a hydrogen or a hydrogen-containing gas for maintaining the activity of the catalyst or regenerating the catalyst's degradation in activity.
Abstract: PROBLEM TO BE SOLVED: To provide a method for simultaneously producing hydrogen and aromatic hydrocarbons including benzene and naphthalene from lower hydrocarbons including methane without causing the detereoration of catalytic activity. SOLUTION: This method simultaneously produces hydrogen and aromatic hydrocarbons consisting mainly of benzene and naphthalene from lower hydrocarbon(s) including >=60 mol% methane in the presence of a catalyst; wherein the feedstock lower hydrocarbon and a hydrogen or a hydrogen- containing gas for maintaining the activity of the catalyst or regenerating the catalyst detereoration in activity are contacted with the catalyst periodically and alternately.

13 Dec 2005TL;DR: Voriconazole is prepared by a process comprising condensing 1-(2,4-difluorophenyl)-2-(1H-1, 2, 4-triazole-1-yl)ethanone with 4-chloro-6-ethyl-5-fluoropyrimidine, in a ketone, ether, aliphatic hydrocarbon, or aromatic hydrocarbon solvent.
Abstract: Voriconazole is prepared by a process comprising condensing 1-(2,4-difluorophenyl)-2-(1H-1,2,4-triazole-1-yl)ethanone with 4-chloro-6-ethyl-5-fluoropyrimidine, in a ketone, ether, aliphatic hydrocarbon, or aromatic hydrocarbon solvent, to give (2R, 3S/2S,3R)-3-(4-chloro-5-fluoropyrimidin-6-yl)-2-(2,4-diflurophenyl)-1-(1H-1,2,4-triazole-1-yl)butan-2-ol.

12 Sep 1996TL;DR: In this article, a catalyst composition and a process for hydrodealkylating a C 9 + aromatic compound such as 1,2,4-trimethylbenzene to a C 6 to C 8 aromatic hydrocarbon such as a xylene are disclosed.
Abstract: A catalyst composition and a process for hydrodealkylating a C 9 + aromatic compound such as, for example, 1,2,4-trimethylbenzene to a C 6 to C 8 aromatic hydrocarbon such as a xylene are disclosed. The composition comprises an alumina, a metal oxide, and a acid site modifier selected from the group consisting of silicon oxides, sulfur oxides, phosphorus oxides, boron oxides, magnesium oxides, tin oxides, titanium oxides, zirconium oxides, molybdenum oxides, germanium oxides, indium oxides, lanthanum oxides, cesium oxides, and combinations of any two or more thereof. The process comprises contacting a fluid which comprises a C 9 + aromatic compound with the catalyst composition under a condition sufficient to effect the conversion of a C 9 + aromatic compound to a C 6 to C 8 aromatic hydrocarbon.
