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： PURPOSE:To provide a method for chemically cleaning petroleum refining equip ment which causes neither the generation of hydrogen sulfide gas nor cracking due to stress corrosion and by which an iron sulfide scale can effectively be dissolved and removed with little corrosion of the base material. CONSTITUTION:An iron sulfide scale deposited on petroleum-refining equipment is contacted with nitric acid, if necessary after being contacted with an alkali to remove an oil. Thus, the scale is removed by dissolution.

摘要： PROBLEM TO BE SOLVED: To obtain a heavy oil having ultra-low sulfur content from a heavy oil containing sulfur, metals, etc., by using a hydrogenation reactor containing a number of catalyst layers filled with a hydrogenation catalyst and satisfying a specific relational formula. SOLUTION: A heavy oil containing sulfur component, metal component, etc., is successively passed from the 1st catalyst layer to the final catalyst layer in a hydrogenation reactor containing >=4 catalyst layers filled with a hydrogenation catalyst and satisfying the formulas Sn =Vn+1 (S is the surface area per 1 m of the hydrogenation catalyst; V is the pore volume per 1 m of the catalyst; (n) is a natural number representing the order of the catalyst layer). The crude heavy oil is brought into contact with hydrogen gas in each catalyst layer under a hydrogenation condition to obtain the objective refined heavy oil.

摘要： PURPOSE:To produce fractions of kerosine and light oil at high yields and selectivities by causing metals having hydrogenolysis activities to be carried by fluorine-modified carriers, wherein porous inorganic oxides are brought into solid-phase contact with solid fluoride. CONSTITUTION:Porous inorganic oxides such as alumina, silica-alumina, etc., are brought into solid-phase contact with solid fluorine compounds such as ammonium fluoride, metallic fluoride, etc., to form fluorine-modified carriers. And the carriers are caused to carry hydrogenolysis active metals such as tungsten, molybdenum, etc., wherein 10-90wt.% of porous inorganic oxides, 2.5-85wt.% of solid fluorine compounds, and 5-50wt.% of hydrogenolysis active metals are contained per total weight of the catalyst respectively. The catalysts thus obtained outstandingly promote hydrogenolysis activities and selectivities, changing thus mineral oil to base oil for lubricating oil having high performances.
