Embodiment
[0017] according to figure 1 In the flow chart in the middle, a set of test equipment is built in the laboratory. R1A and R1B are each filled with 100ml of protective catalyst and 100ml of demetallization catalyst, and R2, R3, and R4 are respectively filled with 200ml of desulfurization catalyst, high-activity desulfurization catalyst and denitrification catalyst. Table 1. The operating conditions of the device are pressure 18MPa, liquid space velocity 0.20h -1 , hydrogen oil ratio (v / v) 800. The purity of the new hydrogen is 99v%, and the raw material oil is sand light and slag-reduced. The properties of raw materials and product control indicators are shown in Table 2. The high-pressure separator gas comes from another set of hot high-pressure separator of the diesel plant in operation, and is washed with water before entering the switchable reactor for sulfidation.
