Abstract
A liquid mixture is prepared by using a liquid phenolic resin (PL-2818) serving as a carbon source. While an inert gas is introduced into the liquid mixture, a released gas is discharged. Then, the liquid mixture is dried in a reduced-pressure atmosphere, and thereby the nitrogen dissolved in the liquid mixture can be reduced. In this way, the amount of nitrogen content after burning can be reduced.
