METHOD FOR THE PRODUCTION OF CALCIUM HYDROXIDE-BASED ABSORBENT MATERIAL SERVING FOR THE RETENSION OF GASEOUS POLLUTANTS DERIVED FROM THE COMBUSTION OF SOLID OR LIQUID COMBUSTIBLES

摘要

Gaseous pollutants are produced during combustion of solid and/or liquid combustibles, causing harmful impacts to the environment. The present invention describes a method meant for the production of absorbent materials exhibiting strong absorption action when injected in dry form into the duct or directly into the boiler. Then, after acting as anti-pollutants, these absorbent materials will be collected and analogously exploited by the anti-polluting equipment (sack-filter/electric filter). Said absorbent materials are based on calcium hydroxide and produced in a specialized manner to acquire enhanced natural absorption features such as special surface, porosity and granularity; the enhancement of these features is based partially to a specialized innovative productive process and partially to the use of known surfactants. This productive process aims at producing two absorbent materials which, being based on calcium hydroxide of special surface (25μ2/gr), are enhanced for being injected in dry form at all-range temperatures throughout the production of pollutants.
