A process for the thermal cracking of hydrocarbons by using a vertical cracking apparatus, comprising introducing raw hydrocarbon material containing components of low volatility or hydrocarbons of low volatility into a heat medium stream of heated steam of 1,600 DEG -2,300 DEG C, said introducing being in the form of a spray of liquid drops countercurrent to said heat medium steam and at an angle in the range of 120 DEG -150 DEG .
