METHOD FOR IMPROVING FLOWABILITY LOSS TEMPERATURE FOR PARAFFIN RAW MATERIAL UTILIZING ZEOLITE NU-86-BASED CATALYST

摘要

petrochemistry. SUBSTANCE: raw material to be processed is brought into contact with catalyst containing zeolite NU-86 and at least one hydrogenation-dehydrogenation element at temperature between 170 and 500 C, pressure between 1 and 250 bar, and volumetric raw material flow rate between 0.05 and 100 h-1 in presence of hydrogen in proportion from 1 to 2000 l per batch of raw material. EFFECT: obtained at least one fraction including at least one averaged distillate with lowered flowability loss temperature and residue including base oils with lowered flowability loss temperature and high viscosity index. 15 cl, 2 tbl, 4 ex
