- 中文摘要: Methane decomposition over metal oxides/SiO2 surface was investigated. At 1400K obtained product distribution of this decomposition varied wihth metal oxide used. The effectiveness of these catalysts has been discussed in terms of activity and C2 selectivity. ThO2/SiO2 was found to be the most effective catalyst for the catalytic decomposition of methane. Positive catalytic effect of ThO2/SiO2 on the pyrolysis has also been confirmed at 1073K. At low reaction conversions, ethane and ethylene are found as major products. Yields of ethylene and other unsaturated products are sensitively inhibited by NO impurities in the methane. A reaction mechanism has been proposed to account observed experimental results.
