Apparatus and method for manufacturing silica-titania catalyst

Abstract

Provided are an apparatus and method for preparing a silica-titania catalyst. The apparatus for preparing a silica-titania catalyst, comprising: precursor supplying units; an oxygen supplying line; a reaction unit; and a recovering unit, wherein the precursor supplying units vaporize a silica precursor and titania precursor and supply them to the reaction unit, wherein the oxygen supplying line supplies an oxygen source to the reaction unit, wherein the reaction unit converts vaporizates of the silica precursor and titania precursor supplied from the precursor supplying units to produce a silica-titania catalyst, wherein the recovering unit cools, condenses and collects the silica-titania catalyst produced at the reaction unit, wherein the recovering unit comprises a cooler for cooling the silica-titania catalyst introduced from the reaction unit, and the cooler comprises a turbulence-forming section on a flow path of the silica-titania catalyst.
