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 prevent the blockage of a catalyst layer of a hydrodesulfurization apparatus caused by a petroleum-based heavy stock oil contg. fine magnetic particles by heating the oil to a specified temp. and passing it through a filter and a high-gradient magnetic separator to remove fine particles having specified particle sizes from it. CONSTITUTION:A petroleum-based heavy stock oil contg. fine magnetic particles is heated to 180-320 deg.C with a heat exchanger using a bottom oil at 300-350 deg.C supplied by a fractionating column in the later stage of a hydrogenation apparatus, is then passed through a filter at a linear velocity of 1-10cm/sec to remove solid impurities having particle sizes of 2.5mum or higher, and is passed through a high-gradient magnetic separator filled with a ferromagnetic filler comprising shell-like metal fragments and having a magnetic gradient of 0.5-20kG/cm at a linear velocity of 0.5-10cm/sec to magnetize iron particles having particle sizes of 25mum or lower to adhere them to the surface of the filler and remove them from the oil, thus reducing the content of fine particles in the stock oil remarkably. Then, the iron particles attached to the filler are removed by switching the separator from iron removing to cleaning, causing the magnetic field around the filler to disappear, and passing the bottom oil through the separator at a linear velocity of 1-10cm/sec.

摘要： PROBLEM TO BE SOLVED: To obtain a low sulfur heavy oil base material economically without causing the plugging of pipes downstream of a hydrogenation tower by hydrotreating a specified feedstock oil repeatedly under specified conditions to form a hydrotreated oil. SOLUTION: A feedstock oil (e.g. vacuum residue) having a dry sludge content of 0-5.0mass% and an S content of 1.0-10mass% is hydrotreated in the 1st-stage tower packed with a hydrogenation catalyst (e.g. a catalyst prepared by impregnating an alumina support with NiO and MoO3 ) under elevated pressure at a temperature (the maximum temperature in the catalyst bed) of 390-450 deg.C to obtain a hydrotreated oil having an S content which is at most 30% of that of the feedstock oil and a content (T) of toluene-insolubles of 10 mass ppm or above. This oil is hydrotreated in the 2nd-stage hydrotreatment tower packed with a hydrogenation catalyst under elevated pressure at a temperature (the maximum temperature in the catalyst bed) which is lower than that in the 1st-stage tower by at least 10 deg.C and is lower than 410 deg.C to obtain a hydrotreated oil having an S content of 30% or below and a T which is at most 50% of that of the hydrotreated oil obtained in the 1st stage.

摘要： PURPOSE: To improve the utilization efficiency of solid medium in the catalytic reaction of heavy petroleum oil, by separating the magnetizable particulate solid medium coated with the metal deposited from the heavy petroleum oil by the catalytic reaction and the nonmagnetizable particulate solid medium using a magnetic separator, and then reusing the latter medium for the reaction.
CONSTITUTION: Heavy petroleum oil consisting of petroleum oil containing fractions having boiling point of ≥190°C (or a product obtained therefrom by hydrogenative desulfurization) is made to react in a catalytic reactor containing particulate solid medium having particle diameter of ≤5cm (pref. 0.1W500μm). After the reaction, at least a part of the medium is extracted from the reactor, and passed through a magnetic separator having a magnetic field of usually 1,000W20,000 gauss or more to separate the magnetizable particles from the nonmagnetizable particles, which are then returned to the catalytic reactor and reused.
