CATALYST FOR REFORMING GASOLINE FRACTIONS AND METHOD FOR PREPARATION THEREOF Russian patent published in 2021 - IPC B01J21/04 B01J21/06 B01J23/656 B01J27/13 B01J27/135 B01J37/02 C10G35/09 

FIELD: catalysts.

SUBSTANCE: proposed is a catalyst for reforming gasoline fractions, containing platinum, rhenium, chlorine and a carrier, wherein the catalyst comprises a surface compound of dehydrated aluminium zirconyl oxodifluoride by the general formula Al₂O₃[ZrOF₂]_x with weight stoichiometric coefficients x from 0.11 to 0.20 with an increased total acidity as a carrier, a total amount of acidic sites over 490 mcmol NH₃/g, with the following content of the components, wt.%: platinum 0.1 to 0.5; chlorine 0.1 to 0.5; carrier the rest. Also proposed is a method for preparing the above catalyst for reforming gasoline fractions.

EFFECT: development of a catalyst ensuring production of a reformate with an octane number of no less than 98 IM when processing raw materials with a high content of naphthenes (35 to 50 wt.%) and a WHSV of 4 to 5 h^-1, wherein the temperature of the catalyst layer is not higher than 470°C.
