subject: Add A Component Of Coal-based Fuels Breakthroughs - China Rear Projection Bulb - Replacement [print this page] Energy-saving environmental protection DMM3 ~ 8 may be a new and efficient alternative to diesel-based Reuters reporter recently from the Chinese Academy of Sciences, Lanzhou Institute of Chemical Physics learned, the Institute has developed a new clean diesel-component poly-methoxy-dimethyl ether synthesis technology is DMM3 ~ 8 preparation for the test. The technology has received U.S. invention patents reached the international advanced level. This means that China's coal chemical industry The main products - methanol and formaldehyde as raw material alternative to a new coal-based synthetic fuels DMM3 ~ 8 worth the wait.
Chinese Academy of Sciences, Lanzhou compounds by DMM3 ~ 8 synthesis technology R & D leader Chen researcher, DMM3 ~ 8 in diesel additive amount of up to 10% -20%. China's annual consumption of 150 million tons of diesel above, such as the harmonic ratio of 15%, the annual increase to 22 million tons of diesel.
China has become the methanol production and consumption of the fastest growing countries, is currently under construction, installation, approval to be built, plans to build the capacity of total 57.21 million tons / year. Industry insiders estimate that, DMM3 ~ 8 successful industrialization, the annual consumption of at least 20 million tons of methanol.
Poly methoxy-dimethyl ether DMM3 ~ 8 is internationally recognized as reduction of fuel consumption and reduce flue gas emissions, a new environment-friendly fuel oxygen component. It first began to study by the United States, Europe, several companies have also been explored, but all there is a low yield, the product distribution is not satisfactory and so on. Chinese Academy of Sciences, Lanzhou compounds are methanol, formaldehyde, two large coal chemical products, using environmentally friendly ionic liquid of new catalytic materials, so that one-way DMMn yield of 50%, where n = 3 ~ 8 a product of up to 70% ~ 80% , but reached only 10% of foreign level.
DMM3 ~ 8 a high cetane number, physical properties and diesel are similar to reconcile the use of diesel engine fuel supply system for vehicles do not need to be transformed. DMM3 ~ 8 environmental performance is good, according to 15% of the harmonic to the diesel fuel can improve diesel fuel quality, increasing the oxygen content of more than 7% reduction over 50% of the tail gas pollution, a significant reduction in nitrogen oxides and carbon monoxide emissions.
It is understood that East China University of Technology is also carried out with dimethyl ether or methanol synthesis DMM3 ~ 8 studies. After the industrialization of technological achievements, not only can solve the two ether must exist to replace diesel engines for vehicles transformation, resulting in dimethyl ether as an alternative fuel vehicle the social problem of high running costs, but also to absorb excess production capacity of dimethyl ether.
