Definitions
- the invention relates to a method for coating ceramic honeycomb bodies with a coating suspension containing catalyst components in a carrier liquid as solids and / or in dissolved form.
- the coated honeycomb bodies are preferably used for the purification of automobile exhaust gases.
- honeycomb bodies For the purification of automobile exhaust gases, catalysts have been used for decades, which are applied in the form of a coating on so-called honeycomb bodies.
- the honeycomb bodies are penetrated by parallel flow channels for the exhaust gases.
- Ceramic honeycomb bodies are made of highly refractory materials. The majority of these are cordierite, a magnesium aluminum silicate. Further common ceramic materials are silicon carbide, aluminum oxide, zirconium oxide, zirconium mullite, mullite, silicon nitride, barium titanate or titanium oxide.
- the honeycomb bodies are made from these materials by extrusion and generally have an open pore structure.
- the flow channels pass through the honeycomb body from an inlet end face to the outlet end face.
- the channels generally have a square cross section and are arranged in a narrow grid over the cross section of the honeycomb body.
- the number of flow channels per cross-sectional area is referred to as cell density, and can be between 10 and 200 cm "2.
- the catalytic coating of the honeycomb body is a so-called dispersion coating, which is applied to the honeycomb body using a mostly aqueous suspension of the catalyst components.
- This coating is also referred to below as washcoat coating.
- the catalyst components contain, for example, finely divided support materials with a high specific surface area, on which the catalytically active components, usually the noble metals of the platinum group platinum, palladium, rhodium, iridium and ruthenium are applied.
- the solids in the catalyst suspension are usually homogenized by wet milling prior to application to the honeycomb body. After grinding, the solids of the suspension have a mean particle size d 5 o between 3 and 5 microns.
- support materials are simple and composite oxides such as active alumina, zirconia, tin oxide, cerium oxide or other rare earth oxides, silica, titania or silicates such as aluminum silicate or titanates such as barium or aluminum titanate and zeolites.
- the different phases of active aluminum oxide of the transition series which can be stabilized by doping with silicon oxide and lanthanum oxide, but also by zirconium oxide and cerium oxide, have proven particularly useful as temperature-resistant support materials.
- the coating of the honeycomb body with a catalytically active layer refers to the coating of the channel walls of the flow channels.
- a coating of the outer shell of the honeycomb body is undesirable.
- the amount of coating applied is generally expressed in terms of the external volume of the honeycomb in grams per liter. The person skilled in the conventional methods for carrying out such a coating are well known.
- the coating For the fulfillment of the demands placed on them, the coating must have a concentration dependent on the respective task. In general, the higher the concentration, the more active and age resistant the coating should be. In practice, depending on the application 10 to 300 g / l needed. However, the maximum achievable concentration can be below the catalytically required concentration for various reasons. Thus, with increasing concentration and thus layer thickness, the adhesive strength of the coating decreases. In addition, large layer thicknesses reduce the hydraulic diameter of the flow channels and thus increase the exhaust back pressure (back pressure) of the catalyst.
- 5,334,570 proposes laying the catalytic coating in the pores of ceramic honeycomb bodies
- the ceramic honeycomb bodies used in this patent had an open porosity of 30 to 45% and average pore diameters of 3 to 10 ⁇ m
- catalytic catalysts have colloidal particle diameters between 0.001 and 0.1, preferably between 0.001 and 0.05 ⁇ m, which penetrate into the pores of the honeycomb bodies upon contact of the honeycomb bodies with a corresponding colloidal coating dispersion
- 90 to 95% of the colloidal washcoat particles could be deposited in the pores of the honeycomb bodies so that the cross-section of the flow channels through the coating hardly diminished and so on t the dynamic pressure was only marginally increased.
- the catalytically active, water-insoluble, pulverulent components are usually suspended in water or an organic liquid, ground, and the substrate is subsequently coated by dipping into the suspension, by pouring over the suspension or by sucking in or pumping in the suspension.
- Object of the present invention is to provide a method for coating porous honeycomb bodies, which allows to coat both the geometric surfaces of the flow channels as well as the pores of the channel walls defined with a catalyst.
- the objective here is to increase the amount of catalytic table active components in the walls of the honeycomb body to optimize the dynamic pressure behavior after coating at the same catalyst mass or the increase in active mass with a comparable dynamic pressure behavior after coating.
- the method uses ceramic honeycomb bodies which are traversed by an inlet end face to an exit end face of parallel flow channels which are delimited from one another by channel walls having an open pore structure.
- a catalyst suspension is used which contains solids suspended in a carrier liquid.
- the method is characterized in that the flow channels are temporarily closed alternately at the inlet and outlet end surfaces, the catalyst suspension flows from the inlet surface to the outlet surface through the honeycomb body and then the mutually closed flow channels are reopened.
- honeycomb body is understood to mean so-called flow-through honeycomb bodies whose flow channels are open at both ends. According to the invention, these flow channels are temporarily closed alternately at inlet and outlet end faces only for the purpose of coating. In contrast, there are the so-called Wandfluß honeycomb body whose flow channels are permanently closed alternately on inlet and outlet end face.
- the method forces the coating suspension to flow through the pore system of the channel wall material during the coating process, unlike conventional honeycomb coating methods.
- the surfaces of the pores are selectively coated.
- the particle size distribution of the solids in the coating suspension and on the mean pore diameter of the ceramic material of the honeycomb body a more or less pronounced filtration of the coating suspension occurs. It is thus possible by appropriate choice of the particle size distribution to set the mass ratio of the deposited in the pores coating suspension defined on the channel walls coating suspension.
- the aim is to fill the pores of the channel walls as completely as possible with catalyst mass in order to keep the coating of the wall surfaces as low as possible at the desired coating concentration.
- the catalyst suspension may optionally be sucked through or pumped through the honeycomb bodies.
- the honeycomb bodies may be dipped into the catalyst suspension or doused with the catalyst suspension if it is ensured that the coating suspension must pass through the channel walls in this process.
- the sealing compounds are not limited. You just have to bring with the known methods in the flow channels and be firm at the usual working temperatures when coating honeycomb bodies. Usually, the honeycomb bodies are coated at room temperature. Suitable are, for example sealing compounds, which at elevated temperature, preferably above 80 0 C, melt or vaporize, can be dissolved out by a solvent or thermally decompose or can be chemically reacted. The latter category includes, in particular, organic sealing compounds which can either be incinerated or ashed. Suitable compositions of this kind are, for example, burnable water-insoluble fillers, such as natural or synthetic waxes, in particular paraffin wax or polymers, such as polyethylene wax. Waxes are preferably having a melting point higher than 8O 0 C.
- all porous honeycomb bodies with open porosity are generally suitable.
- the solids of the coating dispersion must have correspondingly small particle diameters.
- average pore sizes in the range between 3 and 10 .mu.m preference is given to solids having average particle diameters in the colloidal range ( ⁇ 1 .mu.m).
- solids with a broad grain spectrum or solids with a multi-modal grain size distribution can be used.
- Filtration then occurs during coating: particles of small particle diameters are deposited in the pores of the honeycomb body, while the larger particles are deposited on the channel walls.
- highly porous honeycomb bodies with a porosity between 30 and 90% and with an average pore diameter between 10 and 50 ⁇ m are preferably used.
- the inventive method makes it possible, compared to standard honeycomb bodies more catalytically active material applied at a comparable layer thickness on the channel surface or at a comparable hydraulic diameter of the flow channel on the carrier.

- FIG. 2 Section II of FIG. 1
- FIG. 3 Drawing according to photographs of a cross section through a honeycomb body coated according to the invention according to Example 1
- FIG. 4 Section IV of FIG. 3
- FIG. 5 Back pressure as a function of the flow for three honeycomb bodies:
- the flow channels of a honeycomb body made of cordierite were mutually closed with a paraffin wax.
- the honeycomb body had a diameter of 14.4 cm, a length of 15.24 and a cell density of 46.5 cm "2 mm with a thickness of the channel walls of 0.3.
- the porosity of the material was 65% with a mean pore diameter of 22 ⁇ m.
- This honeycomb body was coated with a conventional SCR catalyst of titanium dioxide powder coated with 1.5% by weight of vanadium pentoxide and 9.3% by weight of tungsten.
- the titanium oxide powder was suspended in water and ground by means of a Dyno mill to a mean particle diameter d 50 smaller than 1 micron or dgo ⁇ 3 microns. This suspension was pumped through the honeycomb body and transferred to sucked off schüssiger Washcoat by applying a vacuum at the back of the filter. By repeating this procedure once, the honeycomb body could be coated with a catalyst amount of 240 g per liter of honeycomb volume. After coating, the honeycomb body was dried and calcined, melting and burning the reciprocal paraffin seals of the flow channels.
- Example 2 For comparison, the same honeycomb body was coated as in Example 1 without prior mutual closing of the flow channels with the catalyst suspension, dried and calcined.
- the catalyst mass after coating was 234 g / l.
- FIG. 1 shows a cross section of the honeycomb body (1) coated according to Comparative Example 1.
- FIG. 2 shows the detail II of FIG. 1 enlarged again.
- Reference numeral (2) denotes the flow channels of the honeycomb body and (3) its cordierite skeleton with the pores (4). Almost all of the catalyst material is present as a coating (5b) on the channel walls. Only a small part (5a) has penetrated into the pores of the cordierite framework in the edge region of the channel walls.
- Figures 3 and 4 are the corresponding to Figures 1 and 2 cross-sections of the coated catalyst according to Example 1.
- the pores of the cordierite framework are also filled with catalyst material in the interior of the channel walls (5c) and in the edge region of the channel walls (5a).
- honeycomb bodies with the same dimensions as in the preceding examples were coated analogously to Example 1 and Comparative Example 1 with an iron-exchanged zeolite.
- the coating concentration on the honeycomb body coated according to the invention was 330 g / l honeycomb volume and on the conventionally coated honeycomb body 327.5 g / l.
- Curve A is the dynamic pressure curve for the uncoated honeycomb body, curve B for the coated according to the invention and curve C for the conventionally coated honeycomb body.
- the honeycomb body coated according to the invention has a significantly lower back pressure than the conventionally coated honeycomb body. Although at the selected coating amount of more than 300 g / l, only a small proportion of the coating mass can be absorbed by the pores in the channel walls, this has a very positive effect on the dynamic pressure.
