Carbon Recycling Catalysts by TANAKA Precious Metals
We contribute toward solving the issue of climate change by providing methanation catalysts—which generate methane that serves as a fuel from CO2, a global warming substance that is released into the atmosphere—as well as other catalysts such as carbon dioxide gas reforming catalysts and reverse shift catalysts—which generate CO and hydrogen that serve as chemical raw materials.

Carbon Dioxide Gas Reforming Catalysts (H2O)
Hydrogen (H2) and carbon monoxide (CO), which serve as the raw materials for chemical products and fuel, are generated from carbon dioxide gas (CO2) and methane (CH4).
