Automotive diesel oil pollution of urea benefit: Tiger Chai Qin Source: China Chemical Industry News Update Time: 2013-12-24 Recently, severe fog and haze in the eastern region. The idea that increasing motor vehicles, especially cars should be responsible; also with a view to upgrade the country's oil Pianman progress is an important incentive fog and haze. To solve this problem, the Environmental Protection Department of the Environment and Planning Institute, Ford Research Institute, China Petrochemical Research Institute of Petrochemical scientific and other experts recently convened a symposium. Many experts believe that gasoline vehicles are major emitters of carbon monoxide and hydrocarbons, according to the material properties, which contaminated part of the vehicle did not imagine that serious. The main emissions from diesel vehicles is PM and nitrogen oxides, the formation mechanism of these two conflicting material, in the governance process, reducing a substance will result in an increase of another substance, exhaust gas treatment is relatively difficult. One study showed Tsinghua University, in Beijing, diesel vehicles, especially heavy-duty diesel vehicles, in PM2.5 contribution accounting for up to about 80%, so the pollution control heavy-duty diesel vehicles is an important catch governance PM2.5 hand, which is the most important vehicle of urea. China's automotive product development started late urea solution, currently only a small number of research institutions and enterprises to small batch production according to market demand. 2012 annual sales of the national market is only about 10,000 tons. Beijing is a city of the earliest implementation of the country Ⅳ standard, the annual demand of about 6000 tons, mainly buses use. Shanghai is running less than 1000 Euro Ⅳ car, annual demand of about 1000 tons. However, with the imposition of the country Ⅳ emission standards, is expected to usher in rapid growth.
