Details

1. FEATURES AND SCOPE OF APPLICATION
   RDAS-2 is a kind of de-arsenic catalyst, adopting transition metal oxides as active component and adding special additive. In comparison with the other same kind of industry products, the bulk density of RDAS-2 is 20% lower, thus decreasing expense per loading, and the crushing strength is much higher. Typically, its arsenic capacity and arsenic pick-up accuracy are much superior to other catalysts.
It is widely used for arsenic removing from propylene, ethylene, butylene and other chemical materials under process conditions of high space velocity and high hydrogen arsenide concentration.
