摘要： PROBLEM TO BE SOLVED: To provide a method for manufacturing a metal oxide nanoporous body which exhibits high adhesive strength when stuck to various base materials such as a honeycomb filter and has excellent heat resistance and the coating film of which to be formed on the base material can be thinned.
SOLUTION: The method for manufacturing the metal oxide nanoporous body comprises the steps of: preparing a raw material fluid composition containing at least one colloidal particle of the metal oxide selected from the group consisting of alumina, zirconia, titania, iron oxides, rare earth metal oxides, alkali metal oxides and alkaline-earth metal oxides and raw materials of two or more metal oxides; mixing the raw material fluid composition so that the quantity of the particle size to be decreased (which is the ratio of (the average particle size of the mixed colloidal particles)/(that of the colloidal particles before mixed)) becomes ≥1.3, heat-treating the mixed raw material fluid composition without coprecipitating them substantially and dispersing the metal oxides uniformly on a wall body which has nanopores each having ≤10 nm diameter and constitutes nanopores.

摘要： PURPOSE: To achieve continuous operation by preventing leak of electricity effectively while improving the efficiency of dust collection, by electrostatically collecting soot, etc., in waste gas passing through a flue into a dust collection room and then burning it by an ignition device.
CONSTITUTION: Waste gas discharged from an internal combustion engine is guided to a flue 4 through an inflow pipe 12 and while a center electrode 3 is reduced to a negative one, a static voltage is appied between many rod-shaped electrode members 31 on the surface of the electrode 3 and the internal wall surface of an external cylinder 1 as a counter electorde. Then, soot, etc., contained in the exhaust gas is electrified by corona discharge between the electrodes to be attracted to the counter electrode, and then enters a dust collection room 5 by way of the holes 22 of a ceramic pipe 2 which forms a circumferential side of the flue 4 to stick the internal wall surface of the external cylinder 1. Gas removed from the soot, etc., is discharged out through an outflow pipe 14 and the soot, etc., collected in the dust collection room 5 is burnt by being ignited intermittently by an ignition device 6.
