Patent number: 8715604Abstract: 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.Type: GrantFiled: September 5, 2008Date of Patent: May 6, 2014Assignee: Bridgestone CorporationInventor: Mari Miyano
