What are "Carbon Recycling Catalysts"?
Carbon Recycling Catalysts are precious metal catalyst products that contribute to carbon dioxide capture and utilization (CCU) technologies, which not only reduce CO2 emissions but also capture and convert CO2 into reusable carbon resources. This is a group of precious metal catalyst products that contribute to carbon dioxide capture and utilization (CCU) technology. These catalysts support a range of conversion processes, including dry reforming, reverse shift reactions, and methanation, enabling the effective utilization of CO2 as a valuable feedstock.

TANAKA's Carbon Recycling Catalysts

We provide methanation catalysts that generate methane fuel from CO2, a global warming substance released into the atmosphere, as well as carbon dioxide gas reforming catalysts and reverse shift catalysts that generate CO and hydrogen as chemical feedstocks, thereby contributing to addressing climate change.

Overview of Carbon Recycling Catalysts

Features

  • Uses ruthenium, platinum, and rhodium to meet various catalyst needs
  • High durability from use of precious metals
  • High catalytic activity can be maintained even with low precious metal content, enabling the supply of catalysts at low cost
