IONICON PTR-MS in use - Fischer-Tropsch Process
Filter Efficacy in a Fischer-Tropsch process
Beside the main constituents of syngas, which typically appear in percent concentrations, also trace gas impurities at much lower concentrations can play a crucial role. The catalytic activity of most transition metals is drastically reduced by the presence of sulfur-containing compounds at extremely low concentration, resulting in poisoning of the catalyst. Furthermore, when large amounts of off-gas are being released, also trace concentrations of compounds of extreme toxicity constitute an environmental risk.
IONICON PTR-MS instruments are ideal to monitor filter efficacy. In the figure, we show sampling at two points, before and after syngas passes through a filter. The break-through of the filter can already be detected in its early onset, which can be used to protect sensitive parts in the process and to prevent poisoning of a catalyst.
