A process for preparing hollow particles of aluminosilicates having a spherical shape of allophane type which are hybrid at the core, comprising:

Process for the synthesis of hybrid allophane

The use of hollow particles of hybrid aluminosilicates of imogolite or allophane type, characterized in that they have their external surface functionalized with Al&#x2014;OH units and their internal surface functionalized at least in part with Si&#x2014;R units, with R representing a nonhydrolyzable unit, preferably a hydrocarbon unit, as vehicle for one or more hydrophobic substances, in particular considered in the oil industry, the hydrophobic substances being chosen from any compound containing a linear or branched aliphatic chain having at least 4 carbon atoms, surfactants, biocides and methane clathrates inhibitors.

Application of hybrid aluminosilicates

The present invention relates to a Pickering destabilisation method. The present invention also relates to a method for phase separation, and specifically to a method for separating hydrocarbons for hydrocarbon extraction, as well as to a method for manufacturing porous substrates and to a method for manufacturing finished products.
