This invention relates to a fluidized bed process. More particularly, the present invention is a process for operating a magnetically stabilized fluidized bed by using a magnetizable fluid to fluidize solid particulate nonmagnetizable fluidizable particles. The operating conditions are such that there is substantially no random motion or time-varying pressure fluctuation as measured at a point within the bed.

This invention relates to a process for magnetically stabilizing the operation of contactor columns containing immiscible fluids passing in dispersed countercurrent flow. The process operates by including, in an appropriate fluid phase, a magnetizable component in an amount which does not substantially change the nature of the liquid in that phase and, further, imposing upon at least a portion of the column containing dispersed phases, a magnetic field sufficient to result in substantially diminished radial mixing of the phase containing the magnetizable substance and diminished coalescence of the dispersed phase. The phase containing the magnetizable component passes through the stabilized zone in substantial plug flow.

The present invention encompasses the use of a specific fuel fed electrode in depositing metals from solutions thereof and in the absence of an external applied potential. Basically as shown in FIG. 1, the electrode comprises an electrically conductive porous substrate 3 bearing on one surface thereof a fuel activating catalyst 4. The porosity of the substrate is sufficient that the current density at surface 2 of the substrate 3 opposite the catalyst 4 will assure substantially complete depletion of metal ions very near the surface of the porous substrate, whereby the catalyst surface and the pores remain substantially free of deposited metal.
