Low temperature catalytic partial oxidation of methane for gas-to-liquids applications
The catalytic partial oxidation (CPO) of methane in the presence of steam (low temperature catalytic partial oxidation, LTCPO) over noble metal catalysts was investigated. The “dry” CPO over ruthenium and rhodium catalysts was studied by thermogravimetric analyses coupled with IR spectroscopy. For C...

The “dry” CPO over ruthenium and rhodium catalysts was studied by thermogravimetric analyses coupled with IR spectroscopy.
