Effect Of Pyrolysis Time On Conversion Of Magnesium Sulfate

With the wide application of magnesium sulfate in various industries, we found that when using magnesium sulfate, we generally go to the conversion rate, and we will find that the pyrolysis time has a certain influence on the conversion rate of magnesium sulfate. Learn more about it below.

At the same time, the content of natural gas in the reaction system was increased, so the conversion rate of magnesium sulfate was improved. When the pyrolysis time was longer than When it increases to , the conversion rate of magnesium sulfate only increases by sieving, and magnesium sulfate with different particle sizes is obtained.

Then the specified particle size is the particle size of the sample, and the content of magnesium oxide in the reduction pyrolysis product is determined by atomic absorption spectrometer. Under the pyrolysis conditions, the particle size of magnesium sulfate is the conversion rate of magnesium co-acid. The conversion rate of magnesium sulfate has increased from that to because with the increase of the reaction time, the surface is porous and fluffy, with a high specific surface area. Insulation, good light transmittance, the demand for pure magnesia is increasing year by year, and it is urgent to develop and research. High heating performance and large thermal expansion coefficient are an important inorganic chemical production. Magnesite.The content of magnesium oxide in the pyrolysis product is 25%. The magnesium oxide is high-purity magnesium oxide. Magnesium sulfate is prepared from salt lake magnesium chloride and sulfuric acid, and magnesium sulfate is dehydrated to obtain anhydrous magnesium sulfate. The effects of reduction temperature, pyrolysis time, magnesium sulfate particle size and natural gas flow rate on the conversion of magnesium sulfate were investigated by single factor experiments. The conditions of reduction and pyrolysis were optimized by orthogonal experiments. The pyrolysis products were analyzed and characterized. Preparation conditions of magnesium oxide. The pyrolysis temperature was ℃, the pyrolysis time was to prolong the contact time between magnesium sulfate and natural gas, and the gas flow rate of natural gas was one. Temperature was the main factor affecting the conversion of magnesium sulfate. The conversion rate of magnesium sulfate is reached, the purity of magnesium oxide is reached, and the single molecule of magnesium oxide prepared is uniform.

This paper attempts to prepare high-purity magnesium oxide by reducing and pyrolyzing magnesium sulfate with natural gas. First, magnesium sulfate is prepared by reacting magnesium chloride and sulfuric acid in salt lakes. After dehydration, natural gas is used for reducing pyrolysis. Most of the magnesium production methods are to precipitate magnesium first, and then directly calcine. The above methods have the defects of low pyrolysis efficiency and low product purity, while direct pyrolysis of magnesium sulfate has problems such as high pyrolysis temperature and long decomposition time. In view of the problems existing in the preparation process of high-purity magnesium oxide,
