FIELD: petrochemical processes.
SUBSTANCE: hydrocarbon feedstock including paraffin molecules is brought into contact, under catalytic dewaxing conditions, with catalytic composition containing metallosilicate crystallites, binding material, and hydrogenation component, weight ratio of said crystallites to said binding material ranging between 5:95 and 35:65. Metallosilicate crystallites have crystalline microporous structure and are characterized by that their structure is build from tetrahedral SiO4 blocks and tetrahedral M (Al and/or Fe, and/or B, and/or Ti) blocks or from tetrahedral SiO4 blocks and octahedral M blocks, these blocks being interconnected at their angles through oxygen atoms.
EFFECT: reduced gas formation and increased porosity of catalytic composition.
