摘要： PURPOSE:To produce a diesel gas oil having a sulfur content of 0.05wt.% or below and a hue of -10 or above (in terms of Saybolt color) from a petroleum distillation residue having poor hue, poor oxidation stability and a sulfur content of 0.1-2.0wt.%. CONSTITUTION:This production process comprises the step 1 of bringing a petroleum distillation residue having a sulfur content of 0.1-2.0wt.% and a boiling point in the range of 15-400 deg.C into contact with hydrogen in the presence of a hydrotreatment catalyst prepared by impregnating a porous support with a metal having hydrogenation activity under conditions of a temperature of 330-375 deg.C and a pressure of 45-100kg/cm to decrease the sulfur content to 0.05wt.% or below and the step 2 of bringing the product from the step 1 into contact with hydrogen in the presence of a hydrotreatment catalyst prepared by impregnating a porous support with a metal having hydrogenation activity under conditions of a temperature of 200-300 deg.C and a pressure of 45-100kg/cm to increase the hue of -10 or above (in terms of Saybolt color).

摘要： PURPOSE:To obtain a low-sulfur light oil for diesel engine having low sulfur content and good color with a simple apparatus by hydrogenating a distillate oil of petroleum under specific condition in two stages. CONSTITUTION:A petroleum distillate oil having a sulfur content of 0.1-2.0wt.% and a boiling point of 150-400 deg.C is made to contact with hydrogen at 375-450 deg.C under 45-100kg/cm pressure in the presence of a hydrogenation catalyst produced by supporting a hydrogenation active metal consisting of chromium, molybdenum, tungsten, cobalt and/or nickel on a porous carrier such as alumina until the sulfur content is decreased to 0.05wt.%. The objective light oil for diesel engine is produced by contacting the hydrogenated substance with hydrogen at 200-300 deg.C under 45-100kg/cm pressure in the presence of a hydrogenation catalyst produced by supporting a hydrogenation active metal consisting of chromium, molybdenum, tungsten, cobalt and/or nickel on a porous carrier to improve the Saybolt color value to >=110.

摘要： PURPOSE:To produce a low sulfur diesel oil gas oil having a low sulfur content, and a good hue by subjecting a petroleum distillation fraction to two step hydrogenation treatments under specific conditions. CONSTITUTION:A petroleum distillation fraction having a sulfur content of 0.5-2.0wt.% and a boiling point range of 200-400 deg.C is hydrogenated with hydrogen in the presence of a hydrogenation catalyst such as a catalyst comprising a cobalt-molybdenum active metal carried on an alumina carrier at 371-480 deg.C under a pressure of 10-50kg/cm to reduce the sulfur content to >=0.05wt.%. The hydrogenated oil is brought into contact with hydrogen in the presence of a hydrogenation catalyst at 80-149 deg.C under a pressure of 10-50kg/cm to produce the objective diesel gas oil having a sulfur content of =0 (hue standard value).

SOLUTION: This method for producing a gasoline base comprises a step for bringing a crude benzene fraction into contact with hydrogen under hydrogenating conditions of an existing catalyst containing a group VIII metal of the periodic table supported on an inert inorganic oxide and converting the benzene in the crude benzene fraction into cyclohexane and a step for selectively converting the cyclohexane in the hydrogenated product oil obtained in the step into methylcyclopentane under hydrogenating isomerization conditions of an existing catalyst containing the group VIII metal of the periodic table supported on zeolite, an acidic salt of a heteropoly acid, a ZrO2 containing sulfate radicals or TiO2 containing the sulfate radicals.

摘要： PURPOSE:To obtain easily a highly viscous paving asphalt by mixing a specified oil obtained by solvent-deasphalting a vacuum distillation residue with a specified (semi-)finished petroleum product. CONSTITUTION:A solvent-deasphalted oil containing at least 13wt.% asphaltene and obtained by solvent-deasphalting a vacuum distillation residue is mixed with a finished petroleum product having a flash point of 150 deg.C or above and/or a semifinished petroleum product to produce a highly viscous paving asphalt. Conventionally, a road paved with straight asphalt is problematic in that it easily undergoes rutting, and a countermeasure is to use semiblown asphalt produced by blowing air into a vacuum distillation residue at elevated temperature of 150-300 deg.C for several hours. However, this is disadvantageous in that it requires many production equipments, a road paved with it is easily cracked, and it is easily deteriorated by heating during transportation, storage and mixing with an aggregate. According to this process, a highly viscous paving asphalt free from such disadvantages can be obtained by a simple mixing operation.

摘要： PURPOSE: To obtain high-purity butadiene from a mixture of 4C hydrocarbons, by using a solvent consisting of a phosphate compound such as trimethyl phosphate, dimethyl phosphate, or its mixture as a main component through extractive distillation.
CONSTITUTION: A mixture of 4C hydrocarbons obtained by decomposing thermally petroleums or dehydrogenating butane-butenes, preferably a mixture of 4C hydrocarbons, obtained by hydrogenating the mixture of 4C hydrocarbons in the presence of a catalyst in a liquid or vapor phase so that acetylenes are hydrogenated selectively to make an acetylene content of ≤1,000ppm based on butadiene, is preferably subjected to the first step extractive distillation operation using a selective solvent consisting essentially of a phosphate compound (e.g., triethyl phosphate, etc.) to remove paraffins and olefins, and subjected to the second step extractive distillation operation to remove acetylenes. Consequently, high-purity butadiene is obtained.

摘要： PURPOSE:To maintain a catalyst activity at a high level for a long time and thereby to prevent plugging of the reaction tower, by allowing a specified amount of hydrogen sulfide to be present in hydrogen gas, in carrying out the selective hydrogenation of thermal cracking gasoline by use of a palladium catalyst. CONSTITUTION:In the production of motor gasoline by selectively hydrogenating diolefins contained in thermal craking gasoline which is a normally liquid hydrocarbon mixture produced as a by-product in the production of lower olefins by thermal cracking of petroleum, the thermal craking gasoline is contacted with hydrogen gas containing 100-1,000molppm of hydrogen sulfide over a palladium catalyst at a catalyst layer temperature of 125-250 deg.C and a pressure of 10-80kg/ cm . The above operation makes it possible to hydrogenate selectively and efficiently diolefins in thermal cracking gasoline for a long time and to prevent increase in pressure loss across the reaction tower due to formation of polymerizate on the catalyst.

摘要： PROBLEM TO BE SOLVED: To obtain a lead-free gasoline which contains a specific paraffin component as a gasoline base material, satisfies the volatility and the octane value, even when the benzene content is decreased in the gasoline, and is useful as a fuel for motor cars. SOLUTION: This gasoline contains a specific paraffin component prepared by hydrogenating the reaction product of propylene dimerization, as a gasoline base material, and contains, in the gross basis, (A) 3-15vol.% of 2,3- dimethylbutane, (B) 0-3vol.% of benzene, (C) 0-2mass% of oxygen containing compounds, calculated as oxygen atoms, such as methyl tert.-butyl ether or the like. In order to prepare the paraffin component, for example, the starting propylene is dimerized in a solvent such as toluene in the presence of a catalyst such as a nickel compound and the dimerization product is hydrogenated in the presence of a hydrogenation catalyst such as palladium on alumina at 150-200 deg.C.
