1) EPRES technology has broken through the foreign technology monopoly in this field, achieved obvious technical advantages, and improved the overall technical level and market competitiveness of China's hydrogenation technology.
2) The results of industrial application show that the EPRES hydrogenation catalyst process is simple, advanced in technology and simple in equipment. The use of cheap vulcanizing agents, the preparation cost of off-the-device pre-vulcanization catalysts is low.
3) The use of EPRES technology can not only shorten the start-up time of the hydrogenation unit: but also the quality of the catalyst produced is stable at room temperature, which can significantly improve the sulfidation effect of the catalyst and improve the utilization rate of the catalyst active metal compared with the pre-sulfidation catalyst in the instrument; As a result, considerable economic benefits are created.
4) There is no centralized heat release phenomenon in the heating and activation process of EPRES catalyst, which improves production safety, and the adaptability and practicability of external pre-sulfidation technology are strong, and 5) the production, storage, transportation and filling process of EPRES catalyst do not need nitrogen protection.
6) Using EPRES technology, many catalysts used in refineries across the country are converted from dispersed vulcanization to centralized external pre-vulcanization, which has significant environmental protection performance.
7) EPRES technology can be widely used in the production of off-the-shelf pre-sulfidation of various types of hydrogenation catalysts, which has broad application prospects.
