Sulfur-containing exhaust gas from natural gas processing, petroleum refining, and coal chemical production is a major source of industrial air pollution. To meet global environmental emission standards and recover valuable sulfur resources, the Claus process has become the most widely adopted core technology for industrial sulfur recovery worldwide. As the core functional material of the Claus sulfur recovery unit, the performance of the Claus catalyst directly determines sulfur conversion efficiency, tail gas treatment effect, and the long-term stable operation of the entire production system. High-performance Claus catalysts are therefore indispensable for modern green petrochemical and coal chemical enterprises.
Shandong Xunda Chemical Industrial Group Co., Ltd. is a professional and reliable manufacturer specialized in R&D, production and customization of sulfur recovery catalysts. With years of in-depth cultivation in the catalyst industry, the company focuses on solving the pain points of low conversion rate, poor high-temperature resistance and easy deactivation of traditional Claus catalysts, providing global industrial clients with high-efficiency, durable and cost-effective Claus sulfur recovery catalyst solutions.
Our product, A888 Claus Catalyst, adopts premium Fe₂O₃-SiO₂ composite raw materials and γ-Al₂O₃. Optimized through professional formula adjustment and pore structure design, the catalyst is specially applicable to the main reaction section and regeneration section of Claus sulfur recovery units. It is perfectly suitable for desulfurization and sulfur recovery of various sulfur-containing gas sources, including refinery gas, natural gas, and coal chemical tail gas, covering most industrial sulfur recovery application scenarios.
This A888 Claus Catalyst possesses multiple outstanding industrial advantages that distinguish it from conventional products.
Firstly, it delivers an ultra-high sulfur conversion rate. Thanks to the high specific surface area of modified alumina, the catalyst maximizes reaction contact efficiency, stably boosting the overall sulfur recovery rate to 96%–98%, effectively improving resource utilization and increasing economic benefits for enterprises.
Secondly, it features excellent high-temperature thermal stability. This product maintains a stable crystal structure under high-temperature operation and frequent temperature fluctuations. It effectively resists sintering and active component loss, with a service life 20%–40% longer than ordinary catalysts, greatly reducing frequent replacement costs and downtime losses.
Thirdly, the catalyst boasts ultra-high mechanical strength. It features low pulverization rate and strong compression resistance, which stabilizes reactor bed pressure drop, avoids equipment blockage, and extends equipment maintenance cycles.
Supported by strong enterprise comprehensive strength, Shandong Xunda Chemical Industrial Group Co., Ltd. ensures reliable product quality and flexible services. We own a professional R&D team and three advanced catalyst production lines with an annual output of 9,500 tons, supporting mass supply and personalized customization of product composition, shape and specifications.
Our catalysts and complete sets of technical solutions are exported to the Middle East, Southeast Asia, Europe, North America and other regions, winning unanimous recognition from global clients. Select A888 Claus Catalyst from Shandong Xunda Chemical Industrial Group Co., Ltd. for high-efficiency sulfur recovery, stable production and green industrial upgrading.
