La-Faujasite zeolite activated with boron trifluoride: synthesis and application as solid acid catalyst for isobutane–isobutene alkylation

Abstract The sodium form of Faujasite Y (Na-FAU) zeolite has been synthesized by the hydrothermal method, and it exchanged with ammonium sulphate later lanthanum (III) chloride solutions to obtain La-FAU catalyst. three zeolites Na-FAU, NH 4 + -FAU have characterized microcrystalline X-ray diffraction, fluorescence, surface area, pore volume Brönsted acid sites. catalyst successfully activated boron trifluoride etherate, tested in alkylation reaction isobutane isobutene up 112 h time on stream, since raw showed a rapid deactivation.
