Guard Catalyst (LSFZC) Series
h@hydrogenationcatalyst.com
Catalysts LSFZC – 100, LSFZC – 102, and LSFZC – 103 are a series of efficient resid hydrotreating guard catalyst, which is developed for high sulfur crude oils. The LSFZC-10X series catalysts have the characteristic of high porosity and can effectively remove metal and dirt from the feedstock of hydroprocessing units, therefore protecting the primary catalysts from being polluted and preventing the bed pressure from increasing rapidly.
