Atmosphere control is critical: oxidizing conditions promote lead oxide formation and copper removal via drossing, while reducing or inert atmospheres prevent excessive lead oxidation during antimony removal. Batch Refining Process Stage 1 – Copper Removal (Drossing): Heat to 400-450°C under oxidizing atmosphere. Copper forms ...
The Challenges: Process Variability and Gas Quality Instability in Coal Gasification Coal gasification proceeds through a series of thermochemical reactions that respond strongly to coal properties and operating conditions: Water-gas reaction: C + H2O → CO + H2 Partial oxidation: C + 1/2O2 → CO Boudouard reaction: C + CO2 → 2CO Water-gas shift ...
