HPT-01 series of hydrodesulfurization protectants

Release time:2017-04-10 17:37:10    source:

Long-term operation of the hydrogenation unit, will inevitably according to the nature of different raw materials, there are different degrees of pipeline wall corrosion peeling phenomenon, and in the form of iron salt by the reactor filter, plug the catalyst microporous and bed gap, thus Resulting in bed pressure rise and catalyst deactivation. HPT-01 series of hydrodesulfurization protective agent, provided by me a set of diene saturated, iron, scale effect in one of the new hydrogenation catalyst protection proppant. The agent has a large pore volume and specific surface area; clover-shaped appearance, with excellent compression, wear resistance; moderate particle size, can improve the distribution of logistics. Suitable for all hydrogenation reaction devices, according to the need to fill in the main catalyst between the top of the catalyst and the ball between the ball can reduce the coking scale, reduce the bed pressure drop, to extend the hydrogenation cycle and the use of the catalyst Life, reduce the cost of running the purpose. The protective agent has been successfully applied in Zhenhai Refining and Chemical, Jingmen Petrochemical and other hydrogenation devices, and achieved good results. The main properties of the HPT-01 series hydrodesulfurizing agents are shown in the following table:
