Amanye ama-catalysts
Siphinde futhi sinikeze ama-catalysts e-serial neqembu asetshenziswa ekusebenzeni kwamakhemikhali we-petrochemical kanye nakwemvelo afana nama-catalysts kanye nama-adsorbents kuyunithi ye-anconia Ammonia, iyunithi yokukhiqiza i-hydrogene, i-acetylene hydrogenation Catalyst ekusebenzeni kwe-PE, njalonjalo.
