RETENTION MEMBER FOR RECOVERY OF INORGANIC MATERIAL FROM ORGANIC MATERIAL/INORGANIC MATERIAL COMPOSITE, METHOD OF RECOVERING INORGANIC MATERIAL THEREWITH AND INORGANIC MATERIAL RECOVERY APPARATUS HAVING THE MEMBER

摘要

A method and apparatus for recovering inorganic materials from an organic material/inorganic material composite, designed to reutilize used catalyst particles in the cracking of organic materials to thereby eliminate the need to separate catalyst particles from inorganic materials after the cracking operation and also to discard catalyst particles, thereby attaining recovery of inorganic materials by efficiently treating the organic materials of the organic material/inorganic material composite. These inorganic material recovering method and apparatus can be provided by the use of a retention member for retaining of the composite thereinside, comprised of a wall member having an opening of size allowing passage of catalyst particles but not allowing passage of obtained inorganic materials therethrough. Preferably, the retention member has a spherical basket form.
