Magnetite hematite hydrogen reduction
WebBased on the phase transformation analysis, during the SMR process, limonite was first dehydrated and converted to hematite, and then siderite decomposed to generate magnetite and CO, where CO... WebBiogas produced during anaerobic treatment of sulphate containing wastes, such as distillery waste, invariably contains around 1–3% (v/v) H 2 S. Being highly corrosive, H 2 S reduces the utility of biogas as a fuel for boilers and also makes the generation of electricity from biogas very problematic. Sodium molybdate is known to inhibit sulphate reduction …
