TANAKA PRECIOUS METAL TECHNOLOGIES Co., Ltd. has announced the development of the MOC1-30 series methane oxidation catalyst, which offers enhanced sulfur resistance and sustained purification performance.
The catalyst addresses the global challenge of reducing methane emissions, which have a greenhouse effect approximately 25 times greater than carbon dioxide. This development is timely as the adoption of natural gas-powered systems increases, alongside stricter emission regulations.
The MOC1-30 series maintains more than 80% methane conversion after 1,000 hours of continuous operation at 350℃. This is achieved through a proprietary technology that converts sulfur on the catalyst surface into sulfur trioxide while preserving the integrity of platinum particles, which are crucial for catalytic reactions.
The performance evaluation of the MOC1-30 series demonstrated that it maintains high methane conversion rates even in the presence of sulfur dioxide, outperforming conventional platinum and palladium-based catalysts. This positions the MOC1-30 series as a viable solution for gas engines in marine and stationary applications.
In addition to meeting emission regulations, the MOC1-30 series reduces operating costs by extending catalyst lifespan and diminishing reliance on desulfurization systems. The catalyst's recyclability further supports sustainable resource management.
As the market for gas engines grows, particularly in sectors like ship propulsion and emergency power generation, the MOC1-30 series offers a cost-effective and environmentally friendly solution. TANAKA aims to leverage its integrated value chain capabilities to introduce this catalyst globally, contributing to industrial decarbonization and a carbon-neutral society.
