Up-conversion luminescence is essentially an Anti-Stokes light, which means the radiation energy is greater than the absorbed light. Up-conversion materials are mainly solid compounds doped with rare-earth elements, it can absorb multiple low energy long wave though the metastable level characteristics of rare-earth primary color, so as to make the invisible infrared light that people can not see to visible light.
Applications:Infrared detection in visible light of infrared excitation, biomarker, long afterglow luminous warning signs, fire path signs or the interior Up-conversion Luminescence,Lasers for Up-conversion Luminescence,night light function,IR Laser for Up-conversion Luminescence Changchun New Industries Optoelectronics Technology Co., Ltd. , https://www.lasersciences.com
It is understood that Wu Petrochemical began construction of an oil upgrading and refining project in September last year. The project includes 5 million tons/year atmospheric decompression, 1.2 million tons/year delayed coking, 1.9 million tons/year hydrogenation of coal-diesel, 60,000 tons/year sulfur recovery, 2 million tons/year hydrocracking, 1.8 million Ton/year catalytic feedstock hydrogenation, 80,000 cubic meters/hour hydrogen production, and other sets of production equipment. After all these devices are completed and put into production, the processing capacity of Wuhu Petrochemical will reach 8 million tons/year. By then, Wu Petrochemical will not only provide high-quality gasoline and diesel for Central China, but also provide raw materials for Wuhan's 800,000 tons/year of ethylene.
It is reported that the 1.2 million tons/year delayed coking unit of Wuhua Petrochemical will also be completed, 60,000 tons/year of sulfur plant and 1.9 million tons/year of coal-based diesel hydrogenation unit are under construction.
wall coating as a night light function and so on.
Wubo Petrochemical Co., Ltd. built 5 million tons of atmospheric and vacuum devices
On December 25, Wuhan Petrochemical Plant's 5 million tons/year atmospheric decompression unit was completed by China Communications. After the device is put into operation, the company's comprehensive supporting capacity will reach 6.5 million tons/year.
