China's Fluidized Bed Methanol to Acrylic Industry Technology Ranks in the Forefront of the World
As an important chemical raw material, olefins are the core products of petrochemical industry. The production routes of traditional olefins such as ethylene and propylene are mainly produced by naphtha cracking, and their disadvantage is excessive dependence on petroleum. With the increasingly scarce oil resources in the world and rising international oil prices, it is of great practical significance to explore a new path to produce propylene from non-oil resources. At the same time, China's coal-based energy pattern is difficult to change in a considerable period of time. Clean and efficient use of coal resources is the key to solving China's energy problems and reducing carbon dioxide emissions. Coal-to-olefin technology provides a recognized and viable direction of development. The core of this key technology is to use advanced gas generation technology to convert coal resources into methanol through the channels of coal to syngas, and then to produce low-carbon olefins from methanol. The cost is lower than that of current petroleum. The reduction of propylene by more than half will play an important role in the structural adjustment and industrial upgrading of the traditional coal chemical industry, as well as the comprehensive utilization of energy in China.
At the press conference on the "Mechanical Breakthrough of Fluidized Bed Methanol to Propylene (FMTP) Industry Technology" held at the Great Hall of the People in Beijing, Li Yongwu, president of the China Petroleum and Chemical Industry Association, said: "The breakthrough of this project is worldwide, and its The significance lies in the great practical significance and historical significance of the development of China's energy and coal chemical industry.The successful development of this technology not only fills a gap in the technology of coal to olefins, but also breaks the foreign coal chemical industry. The monopolistic situation of major key technologies will have a major impact on China's transition from a coal chemical production country to a coal chemical technology powerhouse."
What shall we do if the air is dry at home
What if the indoor air is too dry? Learn these methods, you can automatically humidify. Learn quickly, life tips, life tips, life tips
1. Use empty bottles and water cans to contain clean water and put it everywhere in the room. In addition, after cleaning the open glass bottle after daily use, inject clean water and place it in an inconspicuous corner of the room, which is equivalent to adding several small water environments to the room and has an obvious effect on improving the humidity of the room.
2. Fish and green plants.
Raising green plants can urge the room to maintain appropriate humidity, especially ferns, because they can grow healthily under a certain humidity. Watering and often spraying leaves with water are conducive to improving the air humidity in the room.
Large green plants, such as dripping Guanyin and scattered tail sunflower, are themselves an Air Purifier, which can bring a clean and moist atmosphere to the home environment when placed in the room.
3. Increase the frequency of room cleaning. Wipe the ground with a damp mop, humidify it while cleaning, and increase the cleaning frequency to humidify the room several times. Often wipe furniture with a damp cloth can also humidify the room.
4. Dry the washed clothes naturally. The cleaned clothes can omit the drying and drying steps, and can be hung indoors for natural drying, which can effectively increase the humidity of the room.
5. The warm and humid water and gas in the bathroom humidifies the room. After taking a hot bath in winter, the water vapor in the bathroom is thick. At this time, open the bathroom door, the warm and wet water vapor flows to other rooms, and the humidity increases several times in an instant.
6. Humidify the towel on the radiator and put a basin of water under it. Put a wet towel on the heating. The heating has moisture when radiating, which can also increase the air humidity.
7. Often open windows for ventilation. The outdoor air humidity is relatively higher than the indoor air. You can open the window in the morning and afternoon to change the indoor air flow.
8. Use the humidifier aroma diffsuer. Humidifier humidification is one of the commonly used methods of indoor humidification. However, humidifiers need to be regularly cleaned to prevent bacteria in the humidifier from spraying into the air with water spray. They can use Aroma Diffuser, ultrasonic spray, no need to replace STICKER.
