SCR denitration technology is a necessary means for power plants to achieve ultra-clean emissions. Catalysts, as a core part of SCR denitration technology, lose their activity due to wear or blockage during operation. Some of the regenerable catalysts can be reused after regeneration, while the catalysts that cannot be regenerated face the situation of rational utilization and disposal.

With the rapid development of human society and economy, energy and environmental problems have become increasingly prominent. Organic dye wastewater pollution has become one of the most concerned environmental problems. These organic dye molecules not only destroy the ecological environment, but also contain aromatic intermediates which are carcinogenic.

The US White House issued a statement saying that in order to boycott China’s acquisition of US technology, the United States will still impose a 25% tariff on 50 billion Chinese goods, mainly related to the “Made in China 2025” related industries, and also invest in China’s high-tech industries in the United States. Set new limits. The list of specific commodities will be announced on June 15 and tariffs will be implemented shortly thereafter.

With the rapid rise of global energy demand and the increasing problem of greenhouse gas emissions, the deployment of hydrogen energy industry has become one of the important strategies to solve the sustainable development of society, economy and environment. Hydrogen is widely used to synthesize and upgrade liquid fuels to replace traditional petroleum to produce gasoline and diesel. Meanwhile, proton exchange membrane fuel cells (PEMFCs) fueled with hydrogen have high energy conversion efficiency, and the byproduct is only water, which is expected to become the power core of a new generation of vehicles.
