FIELD: petroleum reprocessing. SUBSTANCE: catalyst has, wt.-%: platinum 0.2-1.0; tin 0.02-1.0; chlorine in the form chloride-ion ((Cl-)) 0.02-0.05, and a carrier - titanium-silicalite or aluminium titanate, or silicon titanate (titanium content is 0.2-2.5 wt.-%) - the rest. On this catalyst dehydrogenation of C2-C5-paraffins is carried out at 500-700 C, under pressure 1-2 kg/cm2 at the volume rate 100-10000 h-1. EFFECT: enhanced quality of catalyst. 3 cl, 2 tbl
