| Outline of Final Research Achievements |
Bio-oil/char slurry is combined fuel of the bio-oil and the char. It is an attractive and novel fuel from wood biomass. Fluidized bed reactor for fast pyrolysis was developed to produce the bio-oil and char. The residence time is key factors for quality and quantity of yields (bio-oil). This system shows good performance for short residence time close to a few seconds. The optimum configuration of facility and operation conditions were clarified.
Moreover, the methods of char separation and removal from bed of binary solids mixture (mixture of silica sand as bed material and char particle) was discussed. It is necessary to obtain both good yields and continuous operation. An effective system of a novel fluidized bed, constructed with two sections connected through a slit bottom of the bed was invented. This system shows good performance of char-particle separation and therefore enables the continuous operation.
