Hot 1:Ministry of Industry and Information Technology: iron and steel industry adjustment policy for public comment

The Ministry of Industry and Information Technology (MIIT) recently on the "iron and steel industry adjustment policy (revised in 2015) (draft)" to the public for comment, proposed to 2017 steel capacity scale is basically reasonable, capacity utilization rate of 80% or more, the industry's profitability and return on assets back to a reasonable level. In this regard, the Ministry of Industry and Information Technology on energy saving and emission reduction, market access and exit, product restructuring and environmental protection and other aspects of the relevant recommendations.

MIIT proposes to further organize structural optimization and adjustment, accelerate the pace of mergers and acquisitions, and by 2025, the top ten iron and steel enterprises will account for no less than 60% of the country's crude steel production, and form three to five mega iron and steel groups with strong competitiveness on a global scale. In addition, the technological innovation system will be continuously improved, and a number of innovation platforms such as R&D centers, laboratories and industrial alliances with the functions of prior intervention, follow-up services and promotion and application will be built. Meanwhile, by 2025, pollutant emissions and energy consumption of iron and steel enterprises will fully comply with national and local standards, and solid waste will be 100% utilized.

The Ministry of Industry and Information Technology (MIIT) said it will further build a fair competition, unified and open market environment to guide and standardize the development of the iron and steel industry in the next 10 years. The period of public consultation with the society is from March 20th to April 20th.

Hot 2:Xinjiang reduced carbon dioxide emissions by 1.478 million tons in 2014, realizing a 39% year-on-year increase in wind power and photovoltaic installations

As of 2014, Xinjiang power grid consumption of new energy 17.57 billion kWh, up 105% year-on-year, to accelerate the new energy on-line as a representative of the region's electricity substitution program in recent years has been effective.

Since 2014, State Grid Xinjiang Power has promoted the implementation of a total of 58 electric energy substitution projects, realizing the substitution of 2.372 billion kWh. Equivalent to the consumer side of the reduction of 830,000 tons of direct-fired coal, emission reduction of 1.478 million tons of carbon dioxide, emission reduction of sulfur dioxide, nitrogen oxides, dust and other 108,000 tons.

It is understood that the electricity substitution strategy "to electricity instead of coal, electricity instead of oil, electricity from afar, to clean electricity" as the core. Among them, "electricity instead of coal", that is, the drying room, residential heating, kitchen cooking, etc. to change "coal for electricity", significantly reducing direct coal combustion. In the suburbs of the city, rural areas to promote household electrification and decentralized electric heating. More than 1,800 electric energy substitution projects have been promoted in dry fruit and vegetable drying and modern agriculture in vegetable greenhouses.

"Electricity in lieu of oil" reduces the use of oil and gas by vigorously developing electrified oil and gas field development, electrified rail transportation, and electric vehicles. Up to now, the cumulative implementation of electricity instead of gas unit project 3, substitution amount of about 28 million kWh, is expected to replace the annual amount of 150 million kWh; electric railroad dragging substitution amount of about 4.97 million kWh, the year is expected to replace the amount of about 120 million kWh.

As of 2014, Xinjiang power grid wind power and photovoltaic installed 11.29 million kilowatts, an increase of 39%, Xinjiang grid-connected wind power utilization hours of 2272 hours.

Hot 3:Dalian University of Technology explored a new method of chemical utilization of carbon dioxide

From the Dalian University of Technology was informed that recently, the school's State Key Laboratory of Fine Chemical Industry, "small molecule activation and biomimetic catalysis" Ministry of Education innovation team to explore a new method of chemical fixation of carbon dioxide, the successful design of crystalline compounds - crystalline gradient polycarbonate, to improve the scope of use of carbon dioxide. Improving the use of carbon dioxide.

Chemical immobilization of carbon dioxide has been a common concern among scientists from various countries. However, the high thermodynamic stability of carbon dioxide makes it difficult to be activated and converted into useful chemicals.

Liu Ye, Ren Weimin, and Lv Xiaobing of this university have achieved the asymmetric alternating copolymerization of carbon dioxide with various endocyclic epoxidized alkanes with high activity and high enantioselectivity through the chiral advantageous binuclear cobalt catalysts they created, and the enantioselectivities of the polymerization products are as high as 99%, and a variety of crystalline carbon dioxide copolymers have been obtained. A novel class of crystalline gradient polycarbonates with adjustable melting temperatures within a certain range was successfully designed, which greatly expanded the scope of carbon dioxide use.

Although some of the chiral polycarbonates are crystalline, many are still completely amorphous. The research team found that regardless of whether they are crystallizable or amorphous, chiral polycarbonates with the same structure but different configurations can form highly crystalline polycarbonates with significantly higher heat resistance by simple self-assembly.

The research group also innovatively proposed and realized that chiral polycarbonates with different structures and different configurations can also form highly crystalline polycarbonates after simple self-assembly.
