Abstract

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), real timeframes (1000 h) and real operating cycles (thermal shocks). The results from this study have proven, for the first time reported in the literature, that hollow fibre reactors can be scaled up and that non-PGM impregnated hollow fibre after-treatments are the ideal candidate for the development of commercial residual methane after-treatments.
