On hydrogen purification technology
Thread Content
China has gradually made breakthroughs in palladium membrane technology; this technology can be used to produce high-purity hydrogen for electronic-grade polysilicon. Are there any locations in China that have devices utilizing this technology or manufacturers that use it?
Palladium membrane technology can be used to purify hydrogen for electronic applications, but the processing capacity is limited and the cost is high. When it comes to processing tens of thousands of cubic meters of gas in electronic-grade polysilicon systems, the investment required is enormous
Target membranes are still a long way away from large-scale industrial application!

The target membrane device can generally process only a few hundred cubic meters of hydrogen per hour, and it has high energy consumption. The hydrogen purification method for electronic-grade polysilicon adds a cryogenic adsorption process to the dry recovery using activated carbon developed by CDI Company.
