FIELD: chemistry.
SUBSTANCE: invention relates to hydrotreatment processes. Described is a method of removing paraffin from hydrocarbon material, involving reacting the material with a mixture of ZSM-48 catalysts under catalytic paraffin removal conditions for producing material from which paraffin has been removed, where the mixture of ZSM catalysts contains: a) first type ZSM-48 crystals, having molar ratio of silicon dioxide to aluminium oxide equal to 70-110 and containing inoculating crystals different from ZSM-48, and b) second type ZSM-48 crystals which differ from first type ZSM-48 crystals on one or more properties selected from presence of inoculating crystals different from ZSM-48, crystal morphology, higher kenyaite percentage and higher molar ratio of SiO2 to Al2O3.
EFFECT: high efficiency of removing paraffin from hydrocarbon material owing to use of a a highly active catalyst.
