In the global industrial gas production sector, a revolution in efficiency and environmental sustainability is quietly emerging. Avant Company, with its latest SYAMCAT Z428Q/SYAMCAT Z429Q catalyst series, is at the forefront of this revolution, utilizing self-regenerating technology to achieve unprecedented efficiency leaps in industrial production.

The main causes of methane steam reforming catalyst deactivation include poisoning, carbon deposition, and active component sintering. Typically, adjusting catalyst structure or pre-purifying feed gas can delay deactivation, but regeneration is still necessary after long-term use. Industrial catalyst regeneration generally results in decreased activity and increased operating temperature after each cycle, ultimately requiring replacement. Carbon deposition deactivation can be addressed by oxidizing the deposits, while sintering deactivation requires temperature control or the use of additives to prevent sintering.

Ni-based catalysts are prone to poisoning by sulfur and chlorine. Pre-purification of methane gas is necessary before steam reforming, but small amounts of sulfur may still enter the reaction system. Enhancing sulfur resistance can be achieved by adding additives or using high-temperature hydrogen reduction to remove sulfur species, though this may damage the catalyst surface. Avant Company focuses on the development of steam reforming catalysts and regeneration technologies, aiming to provide efficient, reliable products and services to meet customer needs.

The self-regenerating feature of the SYAMCAT catalyst series significantly simplifies operation, shortens startup time, and improves production efficiency. Its high reducibility ensures rapid reaction initiation and stable production, enhancing production rates and raw material conversion. Additionally, this technology reduces energy consumption and carbon emissions by minimizing activation steps, aligning with green production standards. SYAMCAT series is suitable for various conditions, exhibiting excellent performance and stability. As a patented product, its innovation and reliability are industry-recognized, with Avant committed to providing efficient and eco-friendly industrial gas production solutions.
