XDH-4 Coking Dry Gas Hydrogenation Catalyst

Product Features & Applications

The XDH-4 catalyst exhibits high hydrogenation conversion capabilities for organic sulfur compounds and olefins in feed gases. It is suitable for the hydrogenation process of coke oven dry gas with olefin content <8%, as well as for the hydrogenation conversion of feedstocks such as petroleum distillates, refinery gas, natural gas, field gas, and water gas. It is particularly well-suited for hydrogen production units using coke oven dry gas as feedstock, where it demonstrates excellent performance.

Packaging & Precautions

XDH-4 hydrogenation catalyst is packaged in cardboard drums lined with double-layer plastic bags, with no foreign objects inside the drums. To prevent catalyst breakage, avoid dropping or jarring during transportation. Conduct thorough inspections during storage and ensure protection against moisture. Store in a dry, well-ventilated warehouse. Do not stack outdoors. Strictly prohibit co-storage with acidic or alkaline chemicals and other harmful substances to avoid compromising catalyst activity. When stored in a sealed container for 3 to 5 years, the catalyst activity remains unaffected.
