Scaling up a hollow fibre reactor: A study on non-PGM hollow fibre after-treatments for methane emission control under extreme conditions

Hollow fibre-based after-treatments impregnated with iron and chromium-based oxides (non-PGM) have been tested for residual methane catalytic oxidation under extreme conditions (sulfur concentration 100-times larger than in real conditions), timeframes (1000 h) operating cycles (thermal shocks). The results from this study proven, the first time reported literature, that hollow fibre reactors can be scaled up non-PGM are ideal candidate development of commercial after-treatments. • A after-treatment has synthesised time. was a oxide. catalyst remained active 100 ppmV sulfur dioxide 1000 h. showed excellent thermal stability shocks. This technology reduce annual emissions by 5.58 billion cubic metres.
