FIELD : technological processes. SUBSTANCE : invention relates to the C2-C12 aliphatic hydrocarbons, C1-C5 alcohols, their esters or their mixtures to each other conversion catalyst into the high-octane gasoline component or aromatic hydrocarbons concentrate with their contact with this catalyst under the following conditions : temperature of 200–650 °C, pressure of 0.1–6.0 MPa, the raw materials feed volumetric rate (in liquid) of 0.1–10.0 h-1, i.e., invention also relates to this catalyst using method. Catalyst contains the high-silica zeolite of penthasils group (ZSM-5 or ZSM-11) with the mol ration of SiO2/Al2O3 = 20–150 mol/mol and the sodium oxide residual content of not more than 0.4 wt.%, zinc oxide and/or gallium oxide, lanthanum oxide, may contain one or more of rare earth elements oxides (cerium (IV) and/or neodymium and/or praseodymium), and/or iron (III) oxide and/or magnesium oxide and/or calcium oxide and/or phosphorus pentoxide and/or boron oxide and/or platinum group metal (Pt, Pd) and/or cobalt oxide, contains binder (gamma – Al2O3, and/or silica, and/or synthetic aluminosilicate, and/or clay, and/or zirconia, etc.), strontium oxide, wherein its content in the catalyst composition makes from 0.01 to 3.0 wt.%, zeolite content makes from 20.0 to 90.0 wt.%, zinc oxide content makes from 0.1 to 6.0 wt.%, gallium oxide content makes from 0.1 to 3.0 wt.%, lanthanum oxide (La2O3) content makes from 0.1 to 5.0 wt.%, rare earth elements oxides content (CeO2, Nd2O3, Pr2O3) makes from 0.1 to 1.0 wt.%, the iron (III), magnesium, calcium, phosphorus, boron, cobalt oxides content makes from 0.1 to 3.0 wt.%, platinum group metals (Pt, Pd) content makes from 0.05 to 1.0 wt.%, the binder component content is the balance to 100 wt.%. EFFECT : increase in the liquid C5+ hydrocarbons yield and increase in the aromatic hydrocarbons content in them. 5 cl, 4 tbl, 53 ex
