FIELD: petrochemical process catalysts.
SUBSTANCE: hydrocarbon stock is processed in presence of catalyst containing 50.0-80.0% of ZBN, ZBM, ZSM-5, ZSM-8, ZSM-11-type zeolites with silicate modulus 30-100; 0.5-5.0% Zn or Ga (calculated as metal); no more than 1.0% in sum of promoter selected from Cl, F, Mg, Ca, Sn, B2O3, or their mixture; no more than 0.7% in sum of NaO and/or Fe2O3 admixtures; and alumina (the rest). Hydrocarbon stock is composed of, wt %: C1-C13-n- and iso-paraffins 2.7-99.5, aromatic C6-C12-hydrocarbons up to 25.0, C5-C12-naphtenes up to 38.0, C4-C6-dienes up to 3.0, acetylene hydrocarbons up to 0.85, aliphatic C1-C6-alcohols and their ethers up to 0.5, nitrogen-containing compounds up to 0.1 (on conversion to N), sulfur-containing compounds up to 0.7 (on conversion to S), water up to 0.5, and C2-C8-olefins - the balance.
EFFECT: enabled processing of hydrocarbon stock with different olefin and paraffin contents without extensive separation of impurities from starting material and separation thereof.
