example 1

[0024] This example illustrates the method provided by the invention.

[0025] Such as figure 1 As shown, a slurry 4 is added to the dipping tank 3 . The slurry 4 is made of pseudoboehmite (containing 32% by weight of alumina, produced by Qilu Catalyst Factory), zirconium oxychloride (ZrOCl 2 ·8H 2 O, produced by Beijing Chemical Plant), rare earth chloride (containing 44% by weight of mixed rare earth oxides, wherein lanthanum oxide accounts for 40% by weight of mixed rare earth oxides, cerium oxide accounts for 53% by weight of mixed rare earth oxides, and other rare earth oxides It is prepared by mixing chloroplatinic acid solution containing 0.02082 g / ml platinum, rhodium chloride solution containing 0.0041 g / ml rhodium and deionized water. This slurry 4 contains 7.5% by weight of alumina, 0.5% by weight of zirconia, 1.5% by weight of rare earth oxides (including 0.6% by weight of lanthanum oxide, 0.8% by weight of cerium oxide, and 0.1% by weight of other rare earth ox...

Abstract

A process for coating the active component on the cellular carrier having the particles capturing function includes such steps as immersing one end of the carrier in the active component slurry while applying vacuum to another end of the carrier of forcing the slurry to flow through the channels of carrier, immersing another end in the active component slurry, repeating the first step, and drying.

Description

technical field [0001] The invention relates to a method for coating active components on a honeycomb support. Background technique [0002] Diesel vehicle exhaust purification catalyst is an important means to deal with modern diesel vehicle exhaust and make its emissions meet environmental protection requirements. The catalyst is the same as the automobile exhaust gas purification catalyst in that it is composed of a honeycomb carrier and active components coated on the carrier, and the honeycomb carrier contains many parallel pores. The difference is that the cells contained in the honeycomb carrier of the automobile exhaust gas purification catalyst are open at both ends, and the hole density on the cross section is 46.5-186.0 holes / cm 2 , the cross-sectional area of ​​each hole is 0.91-1.72mm 2 . The honeycomb carrier of the diesel vehicle exhaust purification catalyst contains each pore that has one end of the outlet blocked, and the pore d...
