Abstract
A process for enhancing fluidization in a fluidized bed reactor chamber. In a preferred embodiment, molybdenum oxide is reduced to molybdenum metal in the fluidized bed. An oxidant is introduced into the fluidized bed during the reducing process in order to substantially prevent or reverse the agglomeration of the particles.
Claims37
A method for enhancing fluidization in a fluidized bed reactor chamber comprising the steps of:
- introducing metal oxide particles into a fluidized bed reactor chamber;
- reducing said metal oxide particles;
- and
- introducing an oxidant into the chamber to enhance the fluidization of the reduced particles while the reduced particles are in the chamber.

A method for reducing molybdenum oxide, comprising the steps of:
- introducing molybdenum oxide particles into a fluidized bed reactor chamber;
- reducing the molybdenum oxide particles;
- and
- at least partially oxidizing the reduced particles to enhance the fluidization of the reduced particles while the reduced particles are in the chamber.

A method for reducing MoO.sub.3 to Mo, comprising the steps of:
- introducing MoO.sub.3 into a first fluidized bed reactor chamber containing MoO.sub.2 particles;
- reducing MoO.sub.3 to MoO.sub.2 at a first temperature;
- introducing MoO.sub.2 into a second fluidized bed reactor chamber containing metallic molybdenum particles;
- reducing MoO.sub.2 to Mo particles at a second temperature;
- and
- oxidizing Mo particles to substantially prevent said particles from sticking to each other.
