METHOD FOR PRODUCING POROUS SPHERICAL ABSORBENT FOR SEWAGE SLUDGE COMBUSTION GAS

摘要

Provided is a method for producing a porous spherical absorbent for a sewage sludge combustion gas, comprising the steps of: producing slurry by mixing water with lime powder obtained from slaked lime or limestone and milling the mixture; foaming by mixing the slurry with a foaming agent; inducing gelation by mixing the foaming solution with a gelation solution so as to form a spherical solid; and calcining the formed spherical solid.
