Both TRC413 and TRC10 exhibit strong propane reforming activity that is close to equilibrium composition.

In terms of low S/C, we have been also developing catalysts with improved C deposition resistance. Please contact us for details.

Our reforming catalysts can be used to generate H2 and CO, the raw materials for chemicals and fuel, from carbon dioxide gas (CO2) and methane (CH4), which cause global warming.

Reaction formula: CH4 + CO2 + 4H2O → 6H2 + 2O2 + 2CO

TRC10-24.5A〔Ru〕

H2 generation concentration, SV-dependence

CO generation concentration, SV-dependence

Note: These results are reference data from initial measurements that we performed.
They are not intended to be conditions for the actual machine.

H2 and CO synthesis gas close to equilibrium composition can be generated. Although the deposition of carbon thought to be due to a disproportionation reaction is noted in piping after passing through the catalyst, there is no carbon deposition on the catalyst.

We offer consultations regarding the trial manufacture and contract production of catalysts that have been customized in accordance with customer needs.
