Title:
ハニカム構造体及びその製造方法
Document Type and Number:
Japanese Patent JP5902826
Kind Code:
B2
Abstract:
Provided is a manufacturing method capable of manufacturing a honeycomb structure which uses a TiO2/V2O5/WO3 catalyst, and which has excellent NOX conversion efficiency and thermal durability. This manufacturing method is of a honeycomb structure which is provided with a honeycomb unit in a shape in which multiple cells are partitioned by cell walls, said cells containing at least titanium oxide, vanadium oxide, tungsten oxide and an inorganic binder and extending in the longitudinal direction from one end surface to the other end surface; this manufacturing method is characterized by involving a molding step for molding a material containing titanium oxide, a vanadium raw material, a tungsten raw material, and an inorganic binder into a honeycomb shape to obtain a honeycomb molded body, and a firing step for firing the honeycomb molded body, wherein the oxygen concentration is 21% or greater and the temperature is 450-650°C in the firing step.
