Abstract:
1. A production process for a carbonized product, produced from a carbonized product precursor which is obtained by polymerizing polyaromatic hydrocarbon under the presence of hydrogen fluoride and boron trifluoride, 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 the carbonized product precursor is fed into the above apparatus and subjected to heat treatment, whereby the carbonized product precursor is carbonized and the carbonized product is adhered on the surface of the above granular matters, wherein the granular matters have a true density of 2 g/ml or more, and have a diameter falling in a range of 10 to 50 mm, 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, to thereby separate the carbonized product from the granular matters.
