Chemistry and Technology of Fuels and Oils Aims and scope

A developed HLaY-containing catalyst in an aluminum-pillared montmorillonite matrix in the Na- and CaNa-forms was tested for cracking of vacuum gas oil into the target products gasoline and light gas oil. The gasoline yield increased from 58.5 to 62.5% over the steam-treated catalyst Al(2.5)CaNaHMM + HLaY. The catalyst Al(2.5)CaNaMM + HLaY on unactivated montmorillonite was tested for light gas oil production. The maximum yield of light gas oil of 65.9-65.1% was obtained after steam treatment of this catalyst at a 2:1 catalyst to feedstock ratio. The influence of steam treatment on the phase composition, porous structure, elemental composition, and acidic properties of the studied catalysts was analyzed by XRD, BET, NH3 thermal desorption, and x-ray fluorescence.
