摘要： This invention relates to a stock oil pretreatment supply system adapted to supply heavy petroleum stock oil to a hydrogenator. In order to remove fine iron particles of not larger than 25 mu , which cannot be removed by the conventional techniques, from stock oil, a system consisting of a heater for heating the stock oil to a predetermined temperature by conducting heat exchange between the stock oil and a high-temperature hydrogenated oil at the bottom of a fractionating tower, a back washer-carrying solid filter for the heated stock oil, and a high-gradient magnetic separator for magnetically separating fine magnetic iron particles of not larger than 25 mu from the stock oil is formed, in which the bottom oil in the fractionating tower is used as a magnetic separator cleaning oil. The fine iron particles could be removed from the stock oil by repeating the iron removing operation and cleaning operation. This pretreatment supply system enables the iron particles, which cause a catalyst layer in the hydrogenator to be closed and deteriorated, to be reduced, and the length of time during which a conventional hydrogenator can be operated continuously to be increased.

摘要： A process for the production of a low-sulfur diesel gas oil having a sulfur content of 0.05 % by weight or lower and having a Saybolt color number of -10 or higher, from a petroleum distillate having a sulfur content of 0.1 to 2.0 % by weight and having an inferior color and inferior oxidation stability. The process comprises contacting the petroleum distillate with hydrogen in the presence of a hydro-treating catalyst which has at least one metal and a porous carrier, wherin said metal has a hydro-treating activity and is supported on said porous carrier, at a temperature of 350 to 450 °C, and a pressure of 45 to 100 kg/cm² in the first step to thereby produce materials having a sulfur content of 0.05 % by weight or lower, and contacting further the materials issued from the first step with hydrogen in the presence of a hydro-treating catalyst which has at least one metal and a porous carrier, wherin said metal has a hydro-treating activity and is supported on said porous carrier, at a temperature of 200 to 300 °C, and a pressure of 45 to 100 kg/cm² in the second step to thereby produce the finished low-sulfur diesel gas oil.
