Apparatus is provided for thermal cracking of hydrocarbons, which comprises a reaction column A having a reactor attached thereto, and a regenerator B having a combustion and heating chamber attached thereto (see FIG. 1), wherein the reaction column has a large diameter in the upward portion thereof and smaller diameter in the downward portion thereof, the reactor, using a dilute fluidized layer, being connected with the top of the reaction column, and on the other hand the regenerator has a large diameter in the upward portion thereof and a smaller diameter in the downward portion thereof, the combustion and heating chamber, using a dilute fluidized layer, being connected with the top of the regenerator. Means are provided for connecting the upper part of the reaction column to the lowermost portion of the regenerator, and similar means are provided for connecting the upper part of the regenerator to the lowermost portion of the reaction column. A refractory material maintained under concentrated, floatable, fluidized conditions is caused to circulate between the regenerator and reaction column as heat carrier, and to come in contact with hydrocarbons introduced into the reaction column, wherein thermal cracking results in the production of lower hydrocarbons. Means are provided for the thermal isolation of the reactor and reaction column, and similarly for the combustion and heating chamber and the regenerator. Also provided are means for the introduction of raw material hydrocarbons, steam, air and heat carrier into the apparatus.
