Magnesium oxide was used to modify the commonly used carrier γ-Al2O3 for sulfur-resistant shift catalysts, and the pressurized “original particle size” evaluation device and analytical testing methods such as XRD and SEM were used to evaluate CoO-MoO3/γ-Al2O3+MgO sulfur-resistant shift catalysts. The catalyst was studied. The results show that adding an appropriate amount of magnesium oxide […]
At present, the cobalt product of cobalt salt plants is crude cobalt carbonate, which is precipitated with sodium carbonate, and the liquid is directly discharged after precipitation. The defect of this process is that there is a large amount of sodium sulfate in the discharged waste liquid. The wastewater containing sodium sulfate is not easy
Hebei Messi Biology Co., Ltd. stated that high-purity magnesium hydroxide is a white amorphous powder with an alkaline aqueous solution. It is soluble in dilute acid and ammonium salt solutions, and is almost insoluble in water and ethanol.
