FIELD: oil and gas industry.
SUBSTANCE: invention refers to method for simultaneous making medium fractions and lubricant bases from synthetic paraffin mixtures, including hydrocracking stage (i) and distillation of product of stage (i), where hydrocracking involves addition of solid bifunctional catalyst including: (A) acidic carrier consisting of catalystically active porous solid substance, including silicon, aluminium, phosphorus and oxygen interlinking so that to form mixed amorphous solid substance, characterised by nuclear ratio Si/Al within 20 to 250, ratio P/Al at least 0.1, but lower that 5, total porous amount within 0.5 to 2.0 ml/g, average pore diameter within 2 nm to 40 nm and specific surface area within 200 to 1000 m2/g; (B) at least one metal with hydrogenation-dehydrogenation activity, selected from groups with 6th on 10th of Periodic systems and distributed over specified carrier (A) in amount within 0.05 to 5 wt % relative to total mass of catalyst.
EFFECT: development of method for simultaneous making medium fractions and lubricant bases from synthetic paraffin mixtures.
