PROCESS FOR PREPARING A RAW MATERIAL FOR A LOW-TEMPERATURE CATALYTIC ISOMERISATION

Preparing a raw material for a low-temperature catalytic isomerisation to remove material damaging isomeric catalyst; hydro-catalytic refinement of a light hydrocarbons mixture upon a catalyst containing, as the active components thereof, molybdenum, cobalt and nickel in the form of sulphides applied on alumina, whilst the weight ratio of MoS2 : NiS : CoS is 10 to 14 : 1.5 to 2.5 : 1.5 to 2.5 and the total sulphide concentration on the active alumina is from 13 to 20 wt.%, at pressure from 1.5 to 2.5 MPa, at temperature from 250 to 325 degrees Celsius and volume velocity from 4 to 10 raw-materila volumes/catalyst volume per 1 hr.
