Ageing tests of a La-Sr based catalyst have been performed at 870°C at different apparent contact times, with a feed of the same composition. They show that this catalyst deactivates only very slightly with time on stream. The most sensitive indicator for an ageing phenomenon is the oxygen conversio

A series of PbO-MgO aerogels differing by their atomic Pb/Mg ratios were tested at 720°C for methane coupling using nitrous oxide to ethane and ethylene. The best catalyst (Pb/Mg =OS) gave a C,, overall selectivity of 69%, a high activity (at W/F=0.03 g s cm-') and a good stability with time-on-stre

Addition of trace amounts of H&l to the reactants for metbane oxidative coupling results in the formation of SO, and poisoning of a lanthanum oxide catalyst. Poisoning has little effect on Cx+ selectivity until conversion falls to a low level. The factors controlling catalyst poisoning were found to
