Synthesis, catalysts, construction and modeling Vaknshgrhay oxidation of methanol to formaldehyde Bstrsyal order


One of the chemicals formaldehyde and consumed values ​​in the petrochemical industry is always check and optimize its production processes a large part of the investigation is taken. The present partial oxidation of methanol in formaldehyde using a catalyst of iron oxide, molybdenum oxide in the temperature range $ ^ circ C $ 410-270 in a continuous reactive fluid bed has been studied. Catalyst needed for the process, a process during Hmrsvby of ammonium and nitrate solutions Polar Hptamvlybdat iron is produced. In order to increase the mechanical strength and resistance to catalyst synthesis, the action inoculated with bismuth nitrate on it and then taken up again by calcination reaction in order Bstrsyal useful. During the impact of various parameters such as reaction temperature, gas superficial velocity and the percentage of feed, the reaction rate and operational capacity has been studied reagent. Experimental results obtained with the results of the models presented for fluid bed reactors have been compared. Finally the best model based on reagent performance is marked.
