  • Patent number: 10533140
    Abstract: A method for producing a hydrocarbon liquid fuel including hydrocracking a raw material oil in the presence of a hydrocracking catalyst, at a supplying pressure of hydrogen of from 0.1 to 1.0 MPa, a liquid space velocity of liquid volume of the raw material oil of from 0.05 to 10.0 hr?1, and a flow rate of the hydrogen from 50 to 3,000 NL per 1 L of the raw material oil, wherein the hydrocracking catalyst is produced by a method including stirring a sulfur compound and a cracking catalyst in an aqueous medium to allow liquid-solid separation (step 1); stirring a solid product obtained in the step 1 and a metal component in an aqueous medium to allow liquid-solid separation (step 2); baking a solid product obtained in the step 2 (step 3); and reducing a solid product obtained in the step 3, or reducing a solid product obtained in the step 3, and then subjecting a reduced product to sulfurization treatment (step 4).
    Type: Grant

  • Patent number: 9017476
    Abstract: Disclosed is a modified metal oxide sol that has a large hydrophilizing effect and antistatic effect, can be produced at low cost and is capable of being a coating. Specifically disclosed is a modified metal oxide sol characterized by modification by a functional group represented by formula (1) at 0.55-5.5 mmol per 1 g of metal oxide sol. MOS(?O)2—R1—Si(CH3)n(—O—)3-n (1) {In the formula, M is a hydrogen ion, C1-4 alkyl group, metal ion or ammonium (NR24) group; Rl is a C1-10 alkylene group (may have urethane bonds or urea bonds in the main alkylene chain); R2 may be the same or different and is a C1-5 alkyl group or a hydrogen atom; and n represents 0 or 1}.
