   <Desc/Clms Page number 1> 
 



   Le brevet principal n    553.070   décrit un procédé de produc- tion de noir de carbone et de gaz utiles, comme sous-produits, procédé caractérisé en ce   qu'on' brille   un hydrocarbure dans un four dans des conditions de combustion incomplète pour produire du noir de carbone en suspension à l'état d'aérosol dans des gaz com- bustibles obtenus comme sous-produits, on refroidit brusquement l'aérosol   à une   température de 816 C au moins., uniquement par échange indirect de chaleur, et on sépare le noir de carbone des gaz. 



   Le présent perfectionnement est basé sur la constatation qu'il n'est pas nécessaire de pousser l'abaissement de la tempéra- ture des gaz à une température en dessous de 186 C au sortir du four pour obtenir le résultat cherché. 

 <Desc/Clms Page number 2> 

 



   Suivant ce perfectionnement on opère le refroidissement brusque des gaz contenant l'aérosol, en les refroidissant au sor- tir du four, par échange indirect de chaleur, jusqu'à une tem- pérature à laquelle s'arrête en substance toute réaction. Pour certains noirs de carbone, cette température peut être aussi élevée que   1200 C,   mais elle peut également être inférieure à   12000C   pour d'autres noirs de carbone.

   Principal Patent No. 553,070 describes a process for the production of carbon black and useful gases as by-products, characterized in that a hydrocarbon is ignited in a furnace under conditions of incomplete combustion to produce black. of carbon suspended in the form of an aerosol in combustible gases obtained as by-products, the aerosol is suddenly cooled to a temperature of at least 816 ° C., only by indirect heat exchange, and the gas is separated. carbon black gas.



   The present improvement is based on the finding that it is not necessary to push the lowering of the temperature of the gases to a temperature below 186 ° C. on leaving the oven in order to obtain the desired result.

 <Desc / Clms Page number 2>

 



   According to this improvement, the gases containing the aerosol are suddenly cooled, by cooling them on leaving the furnace, by indirect heat exchange, to a temperature at which all reaction essentially stops. For some carbon blacks, this temperature can be as high as 1200 C, but it can also be lower than 12000C for other carbon blacks.
