GAS OIL COMPOSITION

摘要

A gas oil composition obtained by mixing 5-70 vol.% hydrotreated petroleum oil with 95-30 vol.% gas oil base obtained by mixing a hydrocracked gas oil fraction and/or a dewaxed gas oil base with an environmentally friendly gas oil base produced by contacting a raw oil with a catalyst comprising a given porous inorganic oxide and an active metal under given reaction conditions, the raw oil being one obtained by mixing an animal/vegetable fat and/or an ingredient derived from an animal/vegetable fat with a sulfur-containing hydrocarbon compound. The gas oil composition has a 90% running temperature of 360°C or lower, sulfur content of 10 mass ppm or lower, oxygen content of 1 mass% or lower, fatty acid/alkyl ester content of 3.5 mass% or lower, total acid value of 0.13 mg-KOH/g or less, methanol content of 0.01 mass% or lower, glyceride content of 0.01 mass% or lower, and cold filter plugging point of -5°C or lower. The gas oil composition is excellent in life-cycle CO2 emission characteristics and oxidative stability and in member stability.
