<p>This invention provides with a process to be easily carried out under which organic materials charged into a vaccum dry distillation still is subjected to indirect heating under an entirely automatic closed process so as to form, for example, A heavy oil, carbon or hydrochloric acid and further, at the same time, organic materials may be recovered by gasifying same. According to another embodiment of this invention, it provides with an entirely automatic closed process being capable of a continuous operation with the exception of three hours for cooling a still after eight hours for dry distillation of one cycle; and accordingly a running cost may considerably be reduced.</p> |
