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.
