PURPOSE:To selectively obtain the titled light hydrocarbon at a high yield, by thermally treating paraffin-containing high-boiling hydrocarbon in the presence of a solid super acidic type catalyst under specific operating conditions while restraining the volume of generated gas. CONSTITUTION:Paraffin-containing high-boiling hydrocarbon (e.g., solid paraffin wax) is thermally treated in the presence of a solid super acidic type catalyst, which is prepared in such a manner that a carrier comprising a hydroxide or oxide of the group III and IV metals of the periodic table is treated with sulfuric acid, calcined and stabilized, under conditions of hydrogen pressure >=50atm, hydrogen to feedstock oil ratio >=300Nl/l, liquid space velocity of 0.2-3.0h<-1> and temperature of 150-350 deg.C, to obtain the titled 10C or lower hydrocarbons.
