Catalytic properties of mesoporous crystalline MCM-41 and related materials forhydrocarbon cracking

The catalytic properties of extra-large pore aluminosilicate MCM-41 and a silica-containingVPI-5 were investigated by MAT ( M icro A ctivity T est) using n-hexadecane as a model feed and were then compared with the results obtained from a commercial FCC catalyst (FCC: F luid C atalytic C racking). It could be demonstrated that, by optimizing structural and chemical properties, the new mesoporous crystalline MCM-41 and related materials are suitable as active components in cracking catalysts for “deeper” cracking of high boilding hydrocarbons.
