Abstract: The high antioxidant true sulfurized diesel hydrogenation catalyst has completed its first industrial application on the 1.8 Mt/a diesel hydrogenation unit of the Refining Department 4 of Zhongke (Guangdong) Refining and Chemical Co., Ltd. The start-up process has shown that the high antioxidant true sulfurized hydrogenation catalyst effectively solves the technical bottleneck of conventional sulfurized hydrogenation catalysts being prone to self heating during transportation and loading. Catalyst loading can operate in a flowing air environment with low dust, stable catalyst performance, and convenient start-up process. It significantly simplifies the start-up process and reduces the workload of operators, reducing safety and environmental risks, energy consumption, and material consumption during the start-up phase. The product properties of the device are stable during long-term operation, and the raw materials of the catalyst have strong applicability. The product meets the requirements of automotive diesel indicators.
