ABSTRACT:
Provided is a production process for a carbonized product characterized by comprising the following steps (a) to (b):(a) a step in which metal-made or ceramic-made plural granular matters are charged into a heat treating apparatus which is maintained at a temperature of 400° C. or higher and 700° C. or lower and allowed to move therein and in which a carbonized product precursor is fed into the above apparatus and subjected to heat treatment, whereby the carbonized product is adhered on the surface of the above granular matters and(b) a step in which the carbonized product adhered on the surface of the granular matters is heated at a higher temperature than the heat treating temperature in the step (a) and 900° C. or lower, whereby the carbonized product is separated from the granular matters. The present invention provides a production process for an inexpensive and useful carbonized product by simple apparatus and steps.
