Methods and systems for preparing catalyst, such as chromium catalysts, are provided. The valence of at least a portion of the catalyst sent to an activator is changed from Cr(III) to Cr(VI). The catalyst is prepared or activated continuously using a fluidization bed catalyst activator.

Continuous catalyst activator

A multi-stage fluidized bed synthesizer and process for synthesizing trichlorosilane wherein silicon particles can be fed into one of multiple intercommunicating fluidizing zones in a fluidized bed reactor supplied with fluidizing gas comprising hydrogen chloride. The fluidizing zones can be disposed laterally adjacent one to another, for example side-by-side, or in a horizontal line. Useful embodiments include: feeding the fluidizing gas at different rates and/or compositions to the different fluidizing zones; filtration apparatus to filter the gaseous product and return silicon particles to the reactor and cooling systems for cooling the fluidized bed and the gas volumes above the fluidized beds, if present.

Ferrous powder particles are coated with vaporized phosphorus in a fluid-bed reactor to obtain homogeneous coatings of phosphorus. The coated powders are useful feed for pressed structural parts, exhibiting improved green density, compressibility and sintered density thus improving magnetic and tensile properties.
