METHOD FOR MANUFACTURING IRON SULFIDE COATED POROUS SUPPORTER AND IRON SULFIDE COATED POROUS SUPPORTER MANUFACTURED BY SAMEMETHOD

摘要

The present invention relates to a method for manufacturing an iron sulfide coated porous supporter by using alumina or sand which is a porous material in an inner space as a supporter and an iron sulfide coated porous supporter manufactured thereby. The method comprises: a first step of obtaining iron sulfide slurry by performing stirring after mixing Na_2S solutions and FeCl_2 solutions in an anaerobic chamber; a second step of separating a supernatant from iron sulfide slurry by using a centrifuge and removing the separated supernatant; a third step of obtaining iron sulfide powders in a nanounit by freezing and drying the iron sulfide slurry; a fourth step of manufacturing an iron sulfide suspension by dissolving the iron sulfide powders in de-ionized water in which dissolved oxygen is removed by nitrogen purging; a fifth step of coating the surface of the porous supporter with mackinawite by mixing and stirring the iron sulfide suspension and porous supporter; and a sixth step of obtaining a porous supporter coated with iron sulfide by drying the porous supporter coated with iron sulfide in the anaerobic chamber. In the fifth step, the porous supporter is stirred with the iron sulfide suspension of predetermined pH.
