A. High-purity hydrogen (95%-99%) principally recovered from catalytic reformer product gases often is not enough to meet the total refinery requirements. Hydrogen is also produced from steam reforming of natural gas and mainly naphtha. After pretreatment to remove sulfur compounds, naphtha is mixed with steam and taken to the reforming furnace (650°-850°C), where hydrogen is produced.
