White Honeycomb Ceramic Catalysts Carriers 51% SiO2 For Gasoline Purification
A catalyst is a substance that accelerates the course of a chemical reaction without undergoing an irreversible change. Catalysts are important not only for the chemical industry, but also for solving environmental problems.
Ceramic structures with a high specific surface are used as carriers for catalysts. The high specific surface should be preserved after long-term use, as well as geometry and mechanical properties, which implies the carrier’s resistance to thermal and mechanical stresses and to chemical destruction.

Ceramic catalysts carriers are usually used:
for purification of gasoline and diesel automobile engines exhaust;
for chemical and petroleum refining processes;
for cleaning emissions of power plants and other industrial enterprises.
The main requirements for catalyst carriers include a large surface area, heat resistance, porosity, chemical inertness, mechanical strength.
Ceramic and metal carriers compete with each other: ceramics are often more stable and more economical, and therefore dominate in most sectors. Metal is sometimes preferable because of greater mechanical strength and the ability to manufacture catalysts of a certain geometry using wire, foil or thin-wall honeycomb structures.
Product Characteristics
● Large specific surface area: to ensure full access to the exhaust gas with the catalyst.
● Stable water absorption: to ensure the catalyst evenly firmly attached to the surface of the catalyst carrier.
● Warm-up: after start-up the engine, the temperature of the carrier can reach the catalyst activation temperature in the shortest possible time.
● Low exhaust resistance: the engine’s exhaust resistance is small, to ensure that doesn’t affect the engine performance.
● High strength: the operating environment of the catalyst carrier is in the bumpy car, so the catalyst carrier must be high strength without being external damage.
● Good assembly: the carrier is an exhaust assembly parts, only good appearance and precise dimensions can ensure perfect assembly.
