PROCESS OF CATALYTIC REFORMING OF GASOLINE FRACTIONS ON ALUMINUM-PLATINUM-RHENIUM CATALYST Russian patent published in 2006 - IPC C10G35/85 B01J37/20 B01J23/656 

FIELD: petroleum processing and petrochemistry.

SUBSTANCE: catalytic reforming carried out at temperature in the reforming zone entry not higher than 485°C is supplemented by sulfidizing accomplished by introducing sulfur-containing compounds by doses each constituting 0.001-0.02% sulfur of the weight of catalyst, intervals between doses being not less than 1/2 one dose introduction time and at summary amounts of added sulfur 0.02-0.2% sulfur of the weight of catalyst during additional sulfidizing period. Additional sulfidizing is performed one or several times over the service cycle lasting hundreds or thousands hours. One sulfur dose addition time ranges from 0.5 to 1.5 h.

EFFECT: increased yield of reforming catalysate.
