POROUS GRANULATED CALCINATION PRODUCT AND PRODUCTION METHOD THEREOF
PROBLEM TO BE SOLVED: To provide an alumina porous granulated calcination product that has a large specific surface area as well as homogeneous network-like pores to the interior.SOLUTION: The porous granulated calcination product is produced by firmly connecting innumerable alumina particles while leaving mainly communicated pores in a network-like state over the whole cross-section of granulated product particle; the pore is controlled in the inner diameter by the droplet size of pore-forming agent; and a pore-forming agent (emulsion) is sprayed on the raw material and a coating layer of pore-forming agent is formed over the surface of raw material particles to control the inner diameter of pore.
【課題】大きな比表面積を有するともに、内部まで均質な網目状の気孔を有するアルミナの多孔質造粒焼成物を提供すること。【解決手段】無数のアルミナ粒子同士が、主として連通する気孔を造粒粒子の断面全体に網目状に残存させて固結してなる多孔質造粒焼成物。気孔は、その内径が気孔形成剤の液滴径で制御されている。気孔形成剤（エマルション）を原料に対して噴霧して、気孔形成剤の被覆層を原料粒子の表面に形成して、気孔の内径を制御する。【選択図】図１
