Latest Patents

Hajime Iida holds a patent for a "Catalyst for removing carbon monoxide in hydrogen rich gas and production method therefor." This catalyst is characterized by the support of platinum and rhenium on rutile titania. It demonstrates a high CO conversion at relatively low reaction temperatures, specifically between 200°C and 300°C. The catalyst is noted for its excellent cost/performance ratio due to a reduction in the amount of supported platinum. The optimal weight ratio of supported platinum to rhenium is recommended to be between 3:1 and 1:1, with a particularly effective ratio of 3:2. Furthermore, the catalyst's performance can be significantly enhanced when rhenium is supported first, followed by platinum.
