A CHROMIA/TITANIA CATALYST FOR REMOVING DIOXINS AND A METHOD OF REMOVING DIOXINS BY USINT THE SAME

摘要

PURPOSE: Disclosed are a chromia catalyst supported titania for removing dioxin and a preparation method thereof. CONSTITUTION: The prepared chromia/titania catalyst for removing dioxin has a content of 1-50 t% chrome oxide, desirably 5-40wt%, and +6 oxidation state of supported chrome species is desirable for controlling the dioxin. The removal reaction is operated over 200 deg.C, and below 5,000 hr-1 of space velocity.
