Environmental support and protection agent
This product is based on high purity alumina as the main raw material added to the special components of the protection of the catalyst support material.The structure of the hole within the circle, around the groove to achieve both to ensure a certain compressive strength and increase its specific surface area and porosity.As the product has 40-50% porosity, a large number of micropores and openings can filter oil granular, gel, asphaltene and heavy metals and other impurities. Although these impurities can be filtered out even after passing through the raw material filter,But there are still a considerable part of the particles below 25μm impurities and iron ions still can not filter out.The top of the reactor filled with the protective agent can be unfiltered impurities in raw materials adsorbed in the pores,So as to achieve the goal of protecting the catalyst from coking and protecting the start-up period of the device.
In the treatment of raw materials, the type and content of impurities and different particle size,Users choose different pore sizes and different number of holes of environmental protection agent.Also according to need, with molybdenum, nickel, cobalt and other active ingredients, in order to prevent the catalyst Shen carbon coke and poisoning.
In the petrochemical industry restructuring, hydrogenation, hydrogen production, coker gas, diesel hydrotreating and other devices using the protective agent results show that it can effectively filter impurities;And can effectively protect the catalyst life,Extend the opening period of the device, increase the flow area of oil,Can make the system pressure drop to below 0.1Mpa, the device processing capacity increased by 26.5%, and the penetration of catalytic diesel up to 37% -40%.
