A METHOD OF PREPARING MULTICOMPONENT BISMUTH MOLYBDATE CATALYSTS WITH CONTROLLING PH AND A METHOD OF PREPARING 1,3-BUTADIENE USING THEREOF |
摘要 |
A manufacturing method of a multicomponent bismuth molybdate catalyst for manufacturing 1,3-butadiene is provided to manufactured with a corecipitation method on a co-precipitated solution of which a pH is controlled. A manufacturing method of a multicomponent bismuth molybdate catalyst comprises steps of: preparing a first solution including a precursor of a metallic component of divalent cation, a precursor of a metallic component of 3-valent cation and a bismuth precursor; preparing a second solution dissolving a molybdenum precursor; injecting the first solution into the second solution, co-precipitating the first solution and the second solution, dipping a basic solution of 1~3 molarity into a co-precipitated solution and controlling the co-precipitated solution to pH of 6 ~ 8; obtaining a solid-component by removing moisture after mixing the co-precipitated solution of which a pH is controlled for 1~2 hours; and heat-treating the solid-component to 400~600‹C after drying the solid-component at 20 ~300‹C. |
