XDH-2 Coke Oven Gas Hydrogenation Conversion Catalyst

Product Features & Applications

The XDH-2 Coke Oven Gas Hydroconversion Catalyst is a novel organic sulfur hydroconversion catalyst. Due to its specialized preparation process, the catalyst exhibits approximately double the activity compared to similar products. This catalyst is primarily used for the hydroconversion and removal of organic sulfur from coke oven gas containing less than 10% CO and approximately 5% olefins. Under operating conditions of space velocity (SV) 500–1000 h⁻¹, reaction temperature 380–450°C, and pressure 1.0–2.0 MPa (gauge), the catalyst achieves an organic sulfur conversion rate exceeding 95% for coke oven gas containing 100–250 mg/Nm³ of organic sulfur.

Packaging & Precautions

XDH-2 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 prevent catalyst deactivation.

When stored in a sealed container, the catalyst retains its activity for 3 to 5 years.
