The data of the cracking of vacuum gas oil (VG) and a mixture of VG with fuel oil (M-100) on
HLaY zeolite catalyst based on acid-activated kaolinite of the Pavlodar deposit modified by aluminum are presented.
The synthesis of the kaolinite matrix and the HLaY zeolite catalyst with its use, the physicochemical and acid
characteristics of the catalyst and its constituent components, and the fractional and hydrocarbon compositions of
vacuum gas oil are described. High mesoporosity of the H-form of the used kaolinite (86.2%), modified by
aluminum of the H-form (84.1) and the HLaY catalyst (80.1%), which provide the activity of the sample in cracking
of the mixture with a yield of 32.6% gasoline and 25.9% light gas oil (LG) at 4500
С and in cracking of VG a yield of
38.2% gasoline and 29.4% LG at 5000
С. The gasolines of cracking of LG contain an increased content of iso
paraffins (up to 20.2%) and a low content of aromatic hydrocarbons (24.1%), which makes the catalyst attractive for
cracking a mixture of VG with fuel oil
