TITANIA CARRIER FOR SUPPORTING CATALYST, MANGANESE OXIDE-TITANIA CATALYST COMPRISING THE SAME, APPARATUS AND METHOD FOR MANUFACTURING THE TITANIA CARRIER AND MANGANESE OXIDE-TITANIA CATALYST, AND METHOD FOR REMOVING NITROGEN OXIDES

摘要

Provided are a titania carrier for supporting a catalyst for removing nitrogen oxides, a manganese oxide-titania catalyst comprising the same, an apparatus and a method for preparing the same, and a method for removing nitrogen oxides. More particularly, provided are a titania carrier having a specific surface area of 100 m²/g-150 m²/g, an average pore volume of 0.1 cm³/g-0.2 cm³/g, and an average particle size of 5 nm-20 nm, and an apparatus and method for preparing the same. Provided also are a manganese oxide-titania catalyst comprising the titania carrier and manganese oxide supported thereon, a method for preparing the same, and a method for removing nitrogen oxides using the catalyst. The catalyst has high activity and dispersibility, and thus provides excellent denitrogenation efficiency even in a low temperature range of about 200° C.
