HDAS 1 catalyst

Product Overview

Description

Catalyst HDAS-1 is a new generation of de-arsine catalyst researched and developed and produced by  Liaoning Haitai Sci-Tech Development Co., Ltd. The arsenide is the deleterious poison to the catalytic processing. The minute content of arsenide in feedstock would make the catalyst take place the permanent poisoning and then happen deactivation. Especially, many kinds of noble metal catalysts such as Pt,Pd and so on are more sensitive to arsenic and the poisoning chance is more easier. Therefore, feedstock needs to pre-dearsenicat for guaranteeing the activity and selectivity of the major catalyst in treating the feedstock that behaves high content of arsenic. Catalyst HDAS-1 is a kind of de-arsenic catalyst with high de-arsenic rate and high arsenic capacity. It can be used for arsenic removal of  gasoline distillate that contains high content of arsenic and light diesel distillation. The de-arsenic rate being more than 99%, catalyst HDAS-1 can entirely satisfy the requirements of the technology production.
