Abstract
The invention concerns a conditioned composition comprising at least a liquid absorbed on a support containing a precipitated silica, said silica being in the form of substantially spherical pellets and having: an average pellet size greater than 150 μm; a filling density in compacted state (DRT) less than 0.29; an oversize rate for a sieve with aperture size of 75 μm of at least 88% wt. %; a porous volume (Vd1), consisting of pores with diameter less than 1 μm, greater than 2.0 cm3/g. The invention also concerns the use of said silica as a support for liquid.
