METHOD AND APPARATUS FOR PRODUCING ULTRAFINE PARTICLE CATALYST OR ULTRAFINE PARTICLE CATALYTIC CARRIER

摘要

PURPOSE:To obtain the dry ultrafine particle catalyst effectively and completely without generating any waste liquid or the like by passing the ultrafine particles produced by an evaporating method within glass through a fibrous carrier to stick the ultrafine particles on the fiber surface of the fibrous carrier. CONSTITUTION:The air incorporated in a production chamber 4 is exhausted to introduced the atmospheric gas therein and a crucible 2 is heated by conducting electricity to a heating source 3 to evaporate an evaporating material 1. The produced ultrafine particles of the evaporating material 1 are carried into a sticking chamber 6 via a conveying pipe 5 by using the atmospheric gas as a carrier gas. The ultrafine particles carried together with the carrier gas are allowed to collide against the fiber 7 used as a carrier and stuck on the surface of the fiber 7. The sticking efficiency of the ultrafine particles on the fibrous carrier 7 is changed by the property of the ultrafine particles and the property of the carrier 7 or the like but nearly 100% ultrafine particles can be stuck by selecting suitably the thickness of fiber sheet. Al2O3, Pt, Ni and Pd, etc. can be used as the material of the ultrafine particles.
