METHOD FOR THE PREPARATION OF CARRIERS FOR HETEROGENOUS CATALYSTS AND S DIMENTED HETEROGENOUS CATALYSTS WITH DEVELOPED GEOMETRICAL SURFACE

This method is used in the chemical industry. The derived carriers and precipitated catalysts have a highly-developed geometric surface, and during its production, no costly synthetic flammable and fire-inflammable ingredients are used. Meanwhile, no toxic or corrosive-apt gases are precipitated.Des...

Beschreibung
Zusammenfassung:	This method is used in the chemical industry. The derived carriers and precipitated catalysts have a highly-developed geometric surface, and during its production, no costly synthetic flammable and fire-inflammable ingredients are used. Meanwhile, no toxic or corrosive-apt gases are precipitated.Description : to the mass of the carrier, or the precipitated heterogeneous catalysts before formation, is added a carbamate in the form of granules, whose quantity is between 0.1 and 25% mass, toward the total mass of the carrier, or of the heterogeneous catalyst, before formation. After formation of the carrier or the catalyst, a thermal treatment follows at a temperature of 160 degrees C, determined by the essence of the respective carrier or catalyst.
