A B S T R A C T PROCESS FOR THE PREPARATION OF AN AROMATIC HYDROCARBON MIXTURE C2-C4 paraffins are converted into aromatic gasoline over a crystalline galliumsilicate with a specific crystal structure having a SiO2/Ga2O3 molar ratio between 25 and 250, which silicate has been subjected once or several times to a two-stage treatment comprising reduction at a temperature of 400-650°C and oxidation at a temperature of 350-700°C. Optionally the galliumsilicate is being subjected to precalcining at a temperature of 600 1000°C, the number of times of the two-stage treatment being determined by the fact whether or not said galliumsilicates have been subjected to such precalcination.
