Abstract: Disclosed is a lubricating oil composition. The lubricating oil composition contains a lubricating base oil including mineral base oil, 4 to 15 mass % of an ester compound of a monovalent or polyvalent aliphatic carboxylic acid and a monovalent or polyvalent aliphatic alcohol, 400 to 1200 mass ppm of zinc dialkyl dithiophosphate in terms of a phosphorus element, 500 to 3000 mass ppm of a calcium-based detergent in terms of a calcium element, and 50 to 1000 mass ppm of a boron-modified succinimide-based dispersant in terms of a boron element, on the basis of the total amount of the lubricating oil composition.

Abstract: A method for producing xylene, including a conversion reaction step of bringing a raw material containing a light hydrocarbon having 2 to 7 carbon atoms as a main component into contact with a crystalline aluminosilicate-containing catalyst to produce a product containing a monocyclic aromatic hydrocarbon having 6 to 8 carbon atoms and a xylene conversion step of subjecting the product to a disproportionation reaction or a transalkylation reaction.

Abstract: A method for producing a monocyclic aromatic hydrocarbon having 6 to 8 carbon atoms, including bringing a raw material which contains a light hydrocarbon having 2 to 7 carbon atoms as a main component into contact with a catalyst composition for producing a monocyclic aromatic hydrocarbon having 6 to 8 carbon atoms. The catalyst composition for producing a monocyclic aromatic hydrocarbon having 6 to 8 carbon atoms is coated with an amorphous silicon oxide compound and contains a crystalline aluminosilicate, and the silicon oxide compound is a silicon oxide compound derived from a compound represented by XnSi(OR)4-n, where X represents a hydrogen atom or an alkyl group, R represents an alkyl group, and n represents an integer of 0 to 4.
