Production Line of Honeycomb Ceramic 
Our Company
Huizhou Hompi is a Group company with one sub-factroy who manufactures catalytic converter for diesel vehicles and industrial use which has a building area of 10,000 m² with an investment of 20 million US dollars in 1st phase project, now the annual production capacity could reach up to 5 million Liters.
We make several types of catalyst for diesel exhaust systems, such as DOC, DPF, SCR, which had been successfully entered into the market of North America, South Africa, Brazil, and Netherlands.
Working Principle of DOC+CDPF
Reactions in CDPF
The NO produced by the reaction of NO2 with carbon particles was oxidized to NO2 again, and then continued to react with carbon particles for continuous utilization.
Doc: Oxidation of No to No2 and removal of CO and HC.
CDPF: the captured carbon particles react with NO2 at low temperature to produce CO2 emissions.
