Honeycomb Ceramic Catalyst Carrier as Automotive Emission Catalytic
ConverterDescription:The catalyst carrier is mainly used in the
automotive and other high-temperature process exhaust. The main
material is cordierite, after coated the catalyst, catalytic
conversion of the exhaust, so as to achieve the national emission
standards. It has characteristics of large surface area, small
expansion coefficient, high strength, high water absorption, and
good matching with the catalytic active component, heating up fast
and so on.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.Technical Data

Principle:Using the noble metal catalyst which coated on the
carrier, catalyze the harmful gases such as HC, CO, NOx, etc. at a
suitable temperature, to make the reaction between three kinds of
harmful gases, the reaction equation is as
follows:2CO+O2=CO22C2H6+7O2=CO2+6H2O2NO+2CO=N2+2CO2Packages:/*
