The Production of Hydrogen Gas: Steam Methane Reforming
Figure 1: Steam Methane Reforming Plant Linde Engineering 2 Steam Methane Reforming Process First, water must be heated in a furnace to produce steam. The superheated steam is mixed with natural gas in the reforming reaction, producing hydrogen gas and carbon monoxide. Carbon monoxide from the reforming reaction interacts with water again to produce more hydrogen and carbon dioxide ...

Metallurgical extraction of antimony (Sb) currently has the limitations of high energy consumption and adverse environmental impact. In this study, we proposed a cleaning process to extract Sb by metallurgy and beneficiation based on Sfixing and reduction roasting of Sb2S3. Metallic Sb can be obtained directly by using zinc oxide (ZnO) and carbon as sulfurfixing and reducing agents ...
