Recent Trends in Fluid Catalytic Cracking Patents, Part II: Zeolites
Apr 22nd, 2014 by William Reid | News | Recent News & Articles |
This is the second article in an ongoing review of recent patent trends in the area of Fluid Catalytic Cracking (FCC). In the last installment, we reviewed patents on catalyst additives and demonstrated that relatively few patents had recently issued on FCC additives (e.g., gasoline sulfur reduction catalysts), likely reflecting the current use of gas oil hydrotreaters and naphtha hydrotreaters/desuphurizers, which reduce the need for such additives. The current article covers recent patents relating to zeolites. Review of these patents indicates that the most active area of research regarding zeolites, at least from the standpoint of companies obtaining patent protection, is in the area of zeolite mesoporosity (zeolite pore diameters in the range of 2 to 50 nm).
