に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a honeycomb type deodorizing catalyst. To be more specific, the present invention is capable of converting foul-smelling exhaust gas containing a large amount of dust, which is generated from various odor sources, into a harmless, odorless material without deteriorating performance due to abrasion or peeling of catalyst components caused by dust, and without clogging. This relates to a no-nikum type deodorizing catalyst that converts into gas and removes it.

も問題となっており、公害防止の見地からこれら悪臭成
分の除去が急務とされてきている。In recent years, various types of foul-smelling exhaust gases, such as organic solvent-based foul-smelling exhaust gases generated from printing, painting, resin processing, and surface treatment factories, as well as dust-containing foul-smelling exhaust gases generated from garbage incinerators, scrap preheating furnaces, etc., have become increasingly important from an occupational health perspective. These odor components have become a problem not only in terms of pollution, but also in terms of environmental hygiene, and from the standpoint of pollution prevention, there is an urgent need to remove these foul-smelling components.

と、（４）法は吸着剤の再生、交換等の煩雑な操作がと
もなうことなどである。Conventionally, methods for removing these foul-smelling exhaust gases include (1) atmospheric diffusion using odor stacks, (2) direct combustion method (cleaning method using a 31 scrubber, and (4) adsorption method using adsorbents such as activated carbon. Each method has the following disadvantages: (1) method is ineffective except when the amount of bad odor generated is minute;
Method 1 requires high temperatures of 750 to 900°C, which is disadvantageous due to high fuel costs, and at the same time there is a risk of secondary pollution such as nitrogen oxide (NOx) by-products (Method 31 requires high costs for wastewater treatment) , (4) methods involve complicated operations such as regeneration and replacement of the adsorbent.
以上の様な理由からこれらの方法は脱臭法の決め手とし

している。The catalysts used in this catalytic combustion deodorization method are granular activated alumina supported with noble metals such as platinum and palladium, and base metals such as copper, chromium, and iron.Recently, catalysts used in automobile exhaust gas purification have also been used. Catalysts have been put into practical use in which activated alumina is supported on a cordierite honeycomb carrier with a small pore diameter, and noble metals such as platinum and palladium are supported in a thin layer on the surface. However, granular catalyst V has a large ventilation resistance and cannot process exhaust gas at a high linear velocity.Therefore, it is necessary to have a large exhaust gas flow cross-sectional area, which increases the area occupied by the reactor, and when treating exhaust gas containing dust. This has the disadvantage that the clogging increases ventilation resistance and increases running costs. On the other hand, when using a catalyst using a cordierite honeycomb type body, when treating dust-containing exhaust gas, the noble metal catalyst substance thinly supported on the surface is worn away and peeled off by the hard fine powder in the dust.
This causes a decrease in activity, and the small pore diameter causes an increase in ventilation resistance due to clogging.Furthermore, when exhaust gas containing several r/Nm3 of dust is vented to the catalyst, ventilation 1 to
It has drawbacks such as clogging that becomes unusable within two days.

A grain size of ~6 mm is selected. However, this granular catalyst has a space velocity of 10.000 to 30.000 Hr l.
When using the catalyst layer, the catalyst layer length is limited to about 200% due to the ventilation resistance of the catalyst layer, which results in a large reactor installation cross-sectional area.In addition, scrap preheating furnace exhaust gas,
When processing foul-smelling exhaust gas containing a large amount of dust, such as garbage incinerator exhaust gas, sintering furnace exhaust gas, foundry exhaust gas, etc., even if the layer length is about 100 square meters, airflow resistance increases due to dust clogging in a short period of time, causing running problems. This increases costs and requires complicated operations such as frequent catalyst cleaning and catalyst replacement.

の物性面で問題がある。When this catalyst is used to treat the above-mentioned dust-containing foul-smelling exhaust gas, there are problems such as abrasion of the surface noble metal catalyst by dust, performance deterioration due to peeling, and increased ventilation resistance due to clogging of the small pore size. This type of catalyst also has a space velocity of 10.000 to 50.000 Hr.
When used in a catalytic converter, the limit for the catalyst layer is about 400 mm due to the ventilation resistance of the catalyst layer, and as with granular catalysts, the device has the disadvantage of becoming large-scale.@The catalyst layer length must be shortened. In other words, the fact that the exhaust gas cannot be processed at a high linear velocity means that the gas flow inside the catalyst pores becomes more laminar and less turbulent, which is one of the causes of dust clogging. It also becomes. As a countermeasure against dust clogging, it is possible to use an electric precipitator, a bag filter, etc. to remove dust and deodorize it, but when using a bag filter, for example, the exhaust gas must be cooled once because its heat resistance is low. Since the exhaust gas is then removed from dust, it is necessary to heat the exhaust gas again by burning a fuel such as butane to the treatment temperature before it enters the catalyst layer, which increases fuel costs and running costs. It is extremely advantageous to deodorize by containing dust. Honeycomb-shaped mullite and alumina carriers with relatively large pores (about 4 mm pore diameter) have also been disclosed as deodorizing catalyst carriers, and catalysts in which catalyst materials are directly supported on these carriers are also considered, but mullite When a carrier is used, there are problems with the physical properties of the catalyst.
