Blockchain bidding

1. Australia, Japan and Canada are all developing well. For example, in Japan, even the government has begun to apply the blockchain technology. Some of their government affairs, such as government bidding, are completed on the blockchain platform. There are also high-quality blockchain government affairs platforms in China, such as the blockchain rental platform in xiong'an New District of Hebei Province, the blockchain government affairs platform in Chongqing, and the SMIC blockchain public service platform in Changsha of Hunan Province. They have done well and achieved good results.

POC particle oxidation catalyst (POC) = particle oxidation catalyst

different from gasoline vehicles, only a few new diesel vehicles adopt exhaust after treatment technology. Automobile diesel engine manufacturers have been improving the engine and its control system to meet the emission standards

The most difficult part is to rece the emission of particulates and nitrogen oxides at the same time in the low temperature lean burn environment

the best effect can be achieved by using diesel lean burn NOx removal catalyst and diesel particulate filter

although this technology already exists, it is very expensive. In most cases, advanced particulate oxidation catalyst POC is used, which is characterized by particulate combustion

The catalyst consists of a new low temperature coating and a metal carrier called Ecocat. At the same time, the conversion of HC and CO can reach 80% - 90%

has been tested on several light and heavy engines and vehicles driven by this type of engine (engines up to Euro 0 to Euro 4 standards). The biggest advantage of this scheme is that the price is relatively cheap and maintenance is not necessary. But the sulfur content in diesel oil should be low

POC is a catalytic oxidizer for particulate matter. The working principle is to catch up the particulate matter, and then burn it through the high temperature of exhaust gas (250 ℃ - 500 ℃), so as to achieve the purpose of recing the particulate matter. POC is widely used in light truck. In addition, POC can regenerate actively and DPF needs human intervention

particulate oxidation catalytic converter (POC) can be used to rece particulate matter in diesel exhaust, which belongs to the category of oxidation catalytic converter. The conversion efficiency of particulate matter is higher than doc, but lower than DPF system. The principle is to make the exhaust gas pass through a multi fold channel without blocking, and the particles are adsorbed in the POC, and the accumulated particles are removed by oxidation combustion

because POC requires a higher working temperature, it needs to be used in combination with DOC, which is called PM Kat system by European heavy truck enterprise man, that is, DOC and POC are integrated. Under the oxidation of DOC catalyst, no in the exhaust gas combines with oxygen to form nitrogen dioxide, and the original NO2 in the exhaust gas enters the POC together. Under the action of the catalyst, the molecular bond of N O2 breaks at a lower temperature, and the generated o burns with the captured C particles to form C O2, thus effectively removing the captured particles

POC can only filter the larger carbon particles, but the ability to capture the carbon particles below PM2.5 is low, and the efficiency of recing PM is 30% - 80%, which is better than doc and lower than DPF. The price of POC is lower than that of DPF and higher than that of doc
