The features of ignition of hydrogen-methane and hydrogen-isobutene mixtures with oxygen over Rh and Pd at low pressures

摘要

The flammability limits of stoichiometric mixtures (20-80% H-2 + 80-20% CH4) + O-2 over Rh and Pd were determined in the pressure range 0-200 Torr and the temperature range 200-500 degrees C. It has been shown that the dark reaction in the mixture (80% H-2 + 20% C4H8)(stoich) + O-2 leads to the formation of carbon nanotubes with a mean diameter of 10-100 nm.
