Manufacturers of catalysts for gas pre-purification
Thread Content
I would like to ask about the performance and scale of these three companies in terms of catalysts used for gas purification (TSA): 1. Chengdu Wuhuan New Era Chemical Co., Ltd.; 2. Shanghai Huaxi Chemical Technology Co., Ltd.; 3. Wuhan Colin Fine Chemical Co., Ltd. Also, if anyone knows of other good catalyst suppliers, please recommend them (indicating their performance and scale). By scale, I mean the size of the factories that use these catalysts
Wuhuan Xinrui has a relatively immature PSA, a mediocre TSA, and also a mediocre PTSA. I’ve had contact with them, and the activated carbon adsorbents they purchase are mainly produced by a company in Henan. I saw the adsorbents they bought on site, and they seemed of poor quality – the activated carbon particles were extremely small; it’s likely that these adsorbents need to be replaced every year, and there’s a lot of powder involved. Judge for yourself – the owner of Shanghai Huaxi is the nephew of the owner of Chengdu Huaxi Chemical; their technical skills are exactly the same, and they have both been doing an excellent job for decades. TSA mainly focuses on programmable valves and adsorbents; it’s better to use imported ones, otherwise you’ll regret it later. . .
