FIELD: chemistry.
SUBSTANCE: said invention relates to method for improvement of loss of mobility temperature of hydrocarbon material obtained by Fischer-Tropsch synthesis, in particular to satisfactory-yield conversion of material with high temperature of mobility loss, at least one fraction of which has low mobility loss temperature and high viscosity index for base oil. Method implies utilisation of dewaxing catalyst, which contains at least one zeolite (molecular sieve) chosen from a group of TON type zeolites (Theta-1, ZSM-22, ISI-1, NU-10 and KZ-2), and at least one ZBM-30 zeolite, at least one inorganic porous matrix, at least one hydrogenating/dehydrogenating element, preferentially from group VIB and group VIII of periodic table.
EFFECT: improved loss of mobility temperature for hydrocarbon material obtained by Fischer-Tropsch synthesis.
