A process for preparing high-octane gasoline components consists in that a feed stock, composed of isobutane and olefins, preferably butylenes, in a molar ratio between I and 40, is contacted at temperatures of from about 50 to about 160 DEG C and at pressures of from about 1 to about 40 atm. with a heterogeneous acid catalyst, whose active component is a metal-complex or metaloxopolymeric compound of the general formula Hk(Me<1>) I (Me<2>)mOnXp, wherein k = 1-6; l= 1-3; m=1-5; n=1-10, p= 2-10, dispersed in a porous organic or inorganic matrix, followed by the extraction regeneration of the deactivated catalyst with an organic or inorganic solvent.
