<p>A process for dispersing a fluid in solid particles which comprises the steps of (a) contacting a gas with a fluid composition comprising (i) from 0.01 to 30 weight percent of a polymer and (ii) from 99.99 to 70 weight percent of a liquid diluent, based on the total weight of the polymer (i) and the liquid diluent (ii), to produce a foam, and (b) contacting the produce foam with solid particles of an average size of less than 2500 micrometers, the weight ratio between the foam and the solid particles being from 1:20 to 1:02. When the fluid composition comprises a binder, a granular material is produced which can be pressed to tablets.</p> |
