ShiftMax 217 To protect the methanol steam reforming catalyst ReforMax M from chloride-containing impurities in the methanol feed gas, a protection bed made of ShiftGuard 200 is installed upstream. ShiftGuar 200 can also be used as a fixed bed to protect against chloride contamination upstream of the low-temperature Water Gas Shift (LTS) catalyst ShiftMax 217. The inherent high LTS activity of ShiftGuard 200 further enhances the performance of the low-temperature Water Gas Shift (LTS) catalyst. ShiftMax 217 Stable at high temperatures, Al2O3 can be used to protect fixed-bed catalysts against contamination from tar compounds and dust. The high pore volume ShiftGuard 100-based can be used in a suitable protection bed. ShiftMax 217
