The invention refers to a method for the pyrolysis of C2-C4 alkanes to produce ethylene, propylene, butylene, hydrogen and unsatd. hydrocarbons, which can be widely used in the chem. and petrochem. industry. Described is a method for the pyrolysis of alkanes using radiation, which comprises feeding a stream of gaseous C2-C4 alkanes into a pyrolysis tube; heating the tube externally to heat the alkane stream by means of the tube walls; introducing one or more radiation beams of limited cross section into the alkane stream; addnl., hydrocarbons with one or more double -C=C- bonds and/or CO2, are introduced into the reaction mixt.; the alkane pressure ranges from 0.1 to 10 atm at a radiated power d. in the reaction medium above 10 W/cm2; the reaction medium temp. near the tube walls does not exceed 900°C; the distance between the radiation beam boundary and the tube wall ranges from 0.1 cm to 10 cm. Coherent radiation from a continuous-wave or a repetitively pulsed CO2 laser is used as a radiation source.
