摘要:
The present invention relates to a catalytically active material for ammonia synthesis obtainable by reducing a precursor material having a phase pure spinel structure which itself is obtainable by heating an intermediate having a layered double hydroxide (LDH) structure. The present invention is also directed to a method of forming the catalytically active material and to a method of synthesizing ammonia, decomposing ammonia or both when using the catalytically active material. Moreover, the present invention is concerned with the use of the catalytically active material in the synthesis of ammonia, decomposition of ammonia or both as well as the use of the intermediate and the precursor material in the preparation of the catalytically active material for ammonia synthesis.
摘要:
The present invention relates to a method for producing propylene oxide directly from propane. The method comprises a step of heating a reaction mixture comprising propane and oxygen in a reactor to form a product mixture comprising propylene oxide. It also comprises a step of isolating the propylene oxide from the product mixture. The invention also relates to methods wherein the isolated propylene oxide is further reacted.
