China scientists have made new progress in science and technology — original title in the synthesis gas directly to olefins: Chinese scientists have made new progress in new Beijing on 6 October, in the synthesis gas for olefin (reporter Zhang Su) 6 reporters from China Academy of Sciences was informed that the China scientists have made significant progress in syngas to olefins 6, relevant results published in the journal "nature". Olefin is one of the most important and high value-added chemical raw materials, synthetic fiber, synthetic rubber, high-grade lubricants and other products can not be separated from it. In order to reduce the dependence on oil resources, in recent years, domestic and foreign research has been based on the non oil route. At present, the main processes are as follows: firstly, the synthesis gas is made from coal or natural gas, and then the methanol is synthesized by the synthesis gas conversion. The scientists found that the synthesis gas can be directly prepared by Fischer Tropsch reaction of olefins, the process is shorter, lower energy consumption. However, there are still some problems in the improvement of olefin selectivity and the effective control of product distribution, for example, because of local overheating, a large amount of methane is produced, and the total olefin yield is reduced. Chinese Academy of Sciences, Shanghai Institute of advanced science and technology, Shanghai University of science and technology joint research team recently developed a new catalyst, can be achieved in a mild condition of high selectivity synthesis of olefins. "The selectivity of methane is as low as 5%, the selectivity of low carbon olefin is up to 60%, and the selectivity of olefin is as high as 80%." Chinese Academy of Sciences, Shanghai Institute of advanced research, said Zhong Zhong, which is of great significance to expand the field of synthetic gas catalytic conversion. Zhong Liangshu introduction, the next step of the research team will work with enterprises in the preparation of catalyst amplification, reactor design, process development and other aspects of cooperation, as soon as possible to achieve industrial demonstration and industrialization. Based on the lack of oil, gas and coal resources, the researchers hope to promote the development of coal chemical industry in china. (end) (Lin Lu, commissioning editor He Yingchun)相关的主题文章:
