PP-I-33above 750°. The catalytic properties of 5%Ni/Cr 2 O 3 ⋅ Al 2 O 3 and 5%Ni-2%Au/Cr 2 O 3 ⋅Al 2 O 3 systems are presented in table 1. Presented catalysts achieved 100 % andabout 20 % of CH 4 conversion at 800 °C respectively in POM and OSR reaction. Allsamples showed 100% of methane conversion at 900 °C. The loss of activity wasbelow 1% after 24h in partial oxidation of methane, which was mainly caused byformation of carbon deposition. The nickel and nickel - gold catalysts tested in OSRprocess did not show carbon presence after 24h reaction, but the loss of CH 4 was5% for 5%Ni/Cr 2 O 3 ⋅ Al 2 O 3 probably because of the active phase oxidation.Table 1.
