Natural gas and synthesis gas are vital energy sources and chemical feedstocks. However, their raw forms typically contain sulfur compounds, primarily hydrogen sulfide (H2S) and carbonyl sulfide (COS), which must be removed to prevent environmental pollution, corrosion of equipment, and poisoning of downstream catalysts used in processes like ammonia or methanol synthesis. NINGBO INNO PHARMCHEM CO.,LTD. plays a crucial role in providing the advanced catalysts needed for effective desulfurization.

Activated zinc oxide and copper oxide-alumina catalysts are prominently used in these applications. Activated zinc oxide desulfurizers are known for their effectiveness at normal and low temperatures, forming stable compounds with H2S and COS to reduce sulfur levels to below detectable limits. Their advantages include high sulfur capacity, good strength, and excellent water resistance, making them versatile for purifying various gas streams, including hydrogen, natural gas, and even liquid hydrocarbons like propylene.

Copper oxide-alumina catalysts offer similar benefits and are often chosen for their high performance in specific conditions. These catalysts, often in a strip or granular form, are critical for processes requiring stringent sulfur removal, thereby enabling cleaner energy production and more efficient chemical synthesis. The ongoing development of these fine chemical catalysis solutions by companies like NINGBO INNO PHARMCHEM CO.,LTD. ensures that industries can meet their purification goals, contributing to both environmental protection and economic viability. Understanding the specific needs of your gas stream is crucial for selecting the optimal desulfurization catalyst.
