Description

Shirasu is one of the volcanic ejections from the volcano on Mt.Sakurajima and it is distributed widely around southern Kyushu. Shirasu is an attractive raw material and many products have been developed from it such as Shirasu porous glass, zeolite, Shirasu opal and Shirasu balloon. In this study, the objective is the development of a continuous reactor for a Shirasu microballoon, which diameter is smaller in two orders of magnitude than that of the Shirasu balloon. As a result of manufacturing a Shirasu balloon with the circulating fluidized bed reactor at around 1273K, Shirasu microballoons with several micrometers in diameter can be prepared.
