Catalyst |
摘要 |
A metal oxide catalyst composition is in the form of particles having at least one face formed by solidification of melt in contact with a surface and preferably having at least one channelled surface whereby the pressure drop through a bed of such particles is limited. The particles are made preferably by casting a melt thinly and fracturing the resulting layer. Such a composition comprising iron oxide is a precursor of an ammonia synthesis catalyst.
