Coke oven gas hydrotreating desulfurization catalyst is a high-performance catalytic material designed to efficiently remove sulfur-containing compounds from coke oven gas through hydrogenation processes. Engineered with advanced metal-supported formulations, it ensures optimized sulfur conversion, enhanced reaction kinetics, and prolonged operational stability. This catalyst plays a crucial role in refinery gas purification, clean fuel production, and petrochemical processing, delivering reliable performance for large-scale industrial desulfurization applications.
Product Overview
The coke oven gas hydrotreating desulfurization catalyst is based on a γ-alumina carrier, containing iron-molybdenum active components and special additives. This catalyst is specially designed for the hydrogenation conversion of organic sulfur in coke oven gas, which may contain up to 10% carbon monoxide. It effectively converts organic sulfur into hydrogen sulfide and hydrogenates olefins in the gas, protecting downstream catalysts for continued use. The catalyst offers excellent selectivity, efficiently converting organic sulfur into hydrogen sulfide while minimizing methanation side reactions and nearly completely preserving the effective components of carbon monoxide, thus maintaining stable catalytic activity.
