BASE MATERIAL FOR GAS OIL AND GAS OIL AND METHOD OF PRODUCING THE SAME

摘要

PPROBLEM TO BE SOLVED: To provide a light oil base material which contains a reduced amount of high unit risk PAH and is obtained from readily available petroleum materials by a low energy consumption manufacturing process and light oil. PSOLUTION: Hydrogenation refining is conducted using at least one kind of catalyst containing a porous body containing Ni and Mo as active metal elements to manufacture the light oil base material and the light oil involving 10-20 vol% of the total aromatics, 0.5-1.5 vol% of aromatics with two or more rings, having a 90 vol% distillation temperature of 320-360C, a sulfur content of 10 mass ppm and a total content of high unit risk comounds of 0.2 mass ppm with those compounds less than 0.1 mass ppm in content as 0 mass ppm. The high unit risk comounds are benzo[a]anthracene, chrysene, benzo[b]fluoranthene, benzo[k]fluoranthene, benzo[a]pyrene, indeno[1,2,3-c,d]pyrene and dibenzo[a,h]anthracene.
