HYDROCARBON FRACTION HYDROFINING PROCESS AND HYDROCARBON FRACTION HYDROFINING CATALYST Russian patent published in 2003 - IPC

Abstract RU 2219999 C1

FIELD: petrochemical processes. SUBSTANCE: process is carried out at elevated temperature in presence of hydrogen on hydrogen-activated alumino-platinum hydrofining catalyst, which is spent hydrocarbon isomerization catalyst pretreated with inert gas at 190-200 C and then with inert gas/oxygen mixture (8% oxygen) at 200 to 470 C at gradual treatment rise with possible rise speed 5 to 15 C/h. EFFECT: increased hydrofining efficiency concerning removal of unsaturated and aromatic hydrocarbons as well as sulfur compounds. 3 cl, 3 ex
