| 摘要 | PURPOSE: To obtain light fractions having excellent stability and compatibility in high yields, by a method wherein heavy hydrocarbon oil is heat-treated under specified conditions to obtain heat-treated oil which is then hydrogenated in the presence of a specified catalyst under specified conditions. CONSTITUTION: Heavy hydrocaron oil such as crude oil is pyrolytically decomposed at 400W530°C under a pressure of 0W200kg/cm 2 G and at a residence time of 1minW5hr. If necessary, the pyrolysis oil is subjected to a distillation operation to remove low-boiling fractions. The resulting oil is catalytically hydrogenated at 350W450°C under a pressure of 50W250kg/cm 2 G at a liquid space velocity of 0.1W5hr -1 , and a H 2 /oil ratio of 100W2,000Nl/l in the presence of a catalyst consisting of 0.1W30wt% catalytic metallic component (e.g. V, Mo) for hydrogenation selected from Groups VB, VIB, VII and IB metals of the Periodic Table and 99.9W70wt% porous inorg. oxide carrier (e.g. zeolite) contg. clay minerals haing complicated chain structure composed mainly of magnesium silicate, to obtain light fractions.
