Catalyst for oil refining – FCC
Levasil® CA to improve mass transfer
Our Levasil® CA products contributes to the mechanical strength of the FCC catalyst structure and facilitates efficient mass transport.
The strong binding ability of Levasil® colloidal silica contributes to the mechanical strength of the catalyst structure and in particular to the attrition strength of the catalyst. This results in increased mechanical stability and extended catalyst lifetime. The strong binding ability is primarily related to the high specific surface area of colloidal silica and its reactivity with various oxide and inorganic mineral materials.
Colloidal silica also has an effect on the mesopore size in FCC catalysts, enabling efficient mass transport. The specific surface area of the colloidal silica and the gelling rate are parameters that can be varied to affect the mesopore size.
