ON THE NIO, MOO3 MIXED-OXIDE CORRELATION BETWEEN PREPARATIVE PROCEDURES THERMAL-ACTIVATION AND CATALYTIC PROPERTIES

In order to achieve a better control of the final characteristics of n ickel molybdate catalysts employed in the oxidative dehydrogenation of propane, a study of the dependence of the catalytic activity upon the preparation methods has been undertaken. A new oxalic precursor is co mpared to those precipitated from an ammonia solution and is particula rly studied because it leads to more selective phase beta stabilized a t room temperature.
