Abstract
|
Researchers
employed n-hexane as an n-paraffinic model hydrocarbon to be hydrocracked for
LPG production that can be used both as a fuel in domestic heating appliances
and as high-octane gaseous motor fuels.
They examined catalysts containing 0.15%Pt, 0.30%Pt, or 0.60%Pt loaded on H-MFI zeolite, aluminum-deficient MFI (AD-MFI), or hydrofluorinated MFI zeolite (F-MFI). In addition, the three unloaded modified zeolites were compared as catalysts for n-hexane hydroconversion, whereby the F-MFI catalyst exhibited superior catalytic activity by virtue of acquiring higher acid sites density and strength. The Pt/F-MFI catalysts also exhibited the highest activities by acquiring the highest acid sites density and strength as well as the highest Pt dispersion. |
