HPC catalysts are catalysts used in the hydroprocessing. Hydroprocessing is the name given to a series of chemical reactions that take place as part of oil refining, and include hydrogenation, hydrocracking and hydrotreating. Hydroprocessing is necessary to remove pollutants like sulfur, nitrogen and heavy metals from fuel oils, as well as in the process of catalytic hydrocracking, where large hydrocarbon molecules are cracked into shorter ones that can be used as fuel oils. 更多
