Embodiment 1
[0097] Step 1: Using the atmospheric distillate oil whose physical and chemical properties are shown in Table 1 as the raw material oil, the second distillate oil with a distillation range of 230°C to 300°C is obtained through a diesel fractionator and a diesel stripper.
[0098] Among them, the technological conditions of the diesel fractionation tower are: the pressure at the top of the tower is -38KPa, the temperature at the bottom of the tower is 255°C, and the temperature at the top of the tower is 158°C. The physicochemical properties of the second distillate can be found in Table 2.
[0099] Step 2: Pass the second distillate oil into the reactor, and the reactor is filled with 5A molecular sieve. The physical and chemical properties of the molecular sieve can be seen in Table 3.
[0100] The process conditions of the reactor were as follows: the bed temperature was 290°C, the temperature of the second distillate entering the reactor was 283°C, and the temperature of th...
