Granular mesoporous silica and preparation method thereof

摘要

Disclosed are granular mesoporous silica and a preparation method thereof. The preparation method includes preparing powdered silica containing a structure derivative to form mesopores; preparing a molded precursor including the powdered silica and an inorganic binder or an organic binder; preparing a granular molded article having a predetermined shape by extruding or injection-molding the molded precursor; and removing the structure derivative by calcinating the granular molded article. The granular mesoporous silica represents superior pore characteristics and is used as an adsorbent capable of effectively removing pollutants in water treatment and air pollution treatment.

主权项

1. A preparation method for granular mesoporous silica, the preparation method comprising:
preparing powdered silica containing a structure derivative, wherein the structure derivative forms mesopores; preparing a molded precursor, the molded precursor comprising the powdered silica and an inorganic binder, or an organic binder, or both the inorganic binding and the organic binder; preparing a granular molded article having a predetermined shape by extruding or injection-molding the molded precursor; and removing the structure derivative by calcinating the granular molded article.
