Welcome to Shijiazhuang Baisheng Chemical Co., Ltd
Description:
it is a kind of new sulfide removal adsorbent based on Active zinc oxide as main component.
In addition to keeping excellent performance of desulfurization, it has been improved the physical properties.
It posses the characteristics of high strength, low abrasion, good water resistance, reduced bed pressure and large area of media.
The sulfide-removal adsorbent is mainly used for removal of hydrogen sulfide from natural gas, oil gas, refinery gas, coke oven gas and light oil feedstock .As for the feed oil containing organic sulfide of complex composition, It can be used with organic sulfur hydrogenation catalyst ,which can make sulfur content down to 0.1ppm in outlet.
