Note: These results are reference data from initial measurements that we performed.
They are not intended to be conditions for the actual machine.
TRC10-24.5A〔Ru〕
Methane reforming SV-dependence
Methane reforming S/C ratio-dependence
Note: These results are reference data from initial measurements that we performed.
They are not intended to be conditions for the actual machine.
TRC413-2.4A〔Rh〕
Methane reforming SV-dependence
Methane reforming S/C ratio-dependence
Note: These results are reference data from initial measurements that we performed.
They are not intended to be conditions for the actual machine.
■Characteristics of Carbon deposition
Note: These results are reference data from initial measurements that we performed.
They are not intended to be conditions for the actual machine.
Compared to conventional products, TRC10 and TRC413 can greatly suppress carbon deposition.
■Characteristics of propane reforming
TRC10-10A〔Ru〕
Propane reforming SV-dependence
Amount of H2 generated
Amount of CO generated
Note: These results are reference data from initial measurements that we performed.
They are not intended to be conditions for the actual machine.
Propane reforming S/C ratio-dependence
Amount of H2 generated
Amount of CO generated
Note: These results are reference data from initial measurements that we performed.
They are not intended to be conditions for the actual machine.
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.
Effective Use of CO2 (Carbon Dioxide Gas Reforming)
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
■Characteristics of carbon dioxide reforming
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.
