Which is the best pressure swing adsorption coconut shell columnar activated carbon?
Abroad, there are two companies in Japan: Takeda and Iwaki. In China, there are many companies in Changxing County, such as Changxing Zhongtai and Changxing Kebo. There are still differences in the performance of carbon molecular sieves domestically; the nitrogen recovery rate is low, and their performance degrades rapidly (with a short lifespan). The import price is around 100,000 yuan per ton, while domestic products cost 20,000–30,000 yuan per ton. It is said that Takeda is represented by a trading company in Guangzhou, and there are many fake products on the market. Additionally, Korelli and Dainippon Solarex in Japan also produce it, but it is unknown what the actual performance is like. That’s what I know.
