Catalyst blank carrier<\/h2><\/div>\n\n\n\n

A catalyst blank carrier refers to a carrier material that is not loaded with active components and mainly plays a supporting and dispersing role in the catalyst system. It usually does not have catalytic activity itself. It is like the “skeleton” of a catalyst, and the true catalytic effect relies on the active substances (such as metals, oxides, etc.) loaded on it, while blank carriers are commonly used as experimental controls to eliminate the interference of the carrier itself on the reaction results. \u200c\u200c<\/p>\n\n\n\n

Product Introduction<\/h2><\/div>\n\n\n\n

Honeycomb shaped carrier, also known as inert carrier, is a ceramic based carrier used for automotive exhaust treatment catalysts, made of materials such as cordierite and alumina. This carrier was first developed by Corning in the early 1970s. It has a honeycomb structure with parallel capillary channels distributed inside, with a pore size range of 0.1 to 1 millimeter and approximately 1600 pores per square centimeter. The first batch of commercial ceramic carriers had lower pore density and thicker walls. Nowadays, in ordinary American gasoline or hybrid cars, there are usually two or three carriers in operation.<\/p>\n\n\n\n

Kaolin is the main raw material for synthesizing cordierite honeycomb ceramic carriers, and its purity, sheet-like structure, and chemical composition have a significant impact on the carrier properties. High purity sheet-like raw materials help reduce the thermal expansion coefficient of honeycomb ceramics. Moderate SiO2 content enhances the thermal stability of honeycomb ceramics, while higher Al2O3 content helps to improve compressive strength and wear resistance. The CaO content should be low to reduce the expansion and shrinkage problems during the sintering process, while the ultra-low K2O and Na2O content solves the expansion and melting problems during the sintering process of honeycomb ceramics. At present, most of the kaolin used in car honeycomb ceramics is imported kaolin. Honeycomb ceramic carriers of cordierite are often formed by extrusion molding. When the sheet-like raw material passes through the mold during extrusion molding, the clay particles are subjected to mutual shear, causing the sheet-like raw material to be oriented and arranged along the honeycomb lattice wall. The crystallization of cordierite is generated based on the oriented arrangement of raw materials during firing, thereby reducing its thermal expansion coefficient<\/p>\n<\/div><\/div>\n\n\n\n
