Haber Bosch Process Magnetite Alyst

In the chemical process called HaberBosch method, Magnetite is used as an iron source in catalysts which increases the reactivity between nitrogen and hydrogen to make ammonia. This method, originally designed by Nobel Prize winners Haber and Bosch, is the most used process for largescale ammonia production today.

The catalyst used in the haber process is magnetite fe 3 o 4 fused with smaller amounts of promoters consisting of other metal oxides. the catalyst is ground finely such that it has a large surface area of about 50 m 2 g1, and the magnetite is reduced to iron. the large surface area allows gaseous molecules to rapidly absorb and react.

Iii a catalyst a porous iron catalyst prepared by reducing magnetite, fe 3 o 4. osmium is a much better catalyst for the reaction but is very expensive. this process produces an ammonia, nh 3 g, yield of approximately 1020. the haber synthesis was developed into an industrial process by carl bosch. please do not block ads on this website.
