WebApr 13, 2024 · Topsoe’s SynCOR reformer uses a multi-layered bed of Topsoe’s unique Ni-based catalysts, while JM’s LCH process layout pre-reforms natural gas with a gas-heated reformer to boost energy efficiency. Industrial gases, petrochemicals, and carbon capture and storage (CCS) businesses show considerable interest in such technologies. WebKPIs include C 2 + slip, pressure drop and Z 90 progression. ATE is not a KPI for the pre-reformer, as the SMR’s ATE would be close to zero throughout the expected life of the catalyst if the C 2 + is within the guaranteed limit. However, the SMR and WGS equilibrium temperatures can be calculated and compared with the observed temperatures.

WebThis has a threefold effect; firstly, as there is more reforming reaction near the inlet of the tube, there is a lower process gas temperature due to the increased heat of reaction required. Secondly, the hydrocarbon content of the process gas is reduced. And finally as more hydrogen is produced carbon formation is suppressed.
