Abstract
Official abstract text for this publication.
The use of hollow particles of hybrid aluminosilicates of imogolite or allophane type, characterized in that they have their external surface functionalized with Al—OH units and their internal surface functionalized at least in part with Si—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.
First claim
Opening claim text (preview).
The invention claimed is: 1. Method for at least one of trapping and extracting hydrophobic substances, comprising the steps of: providing a bioreactor media containing one or more hydrophobic substances, and contacting said one or more hydrophobic substances with a vehicle to at least one of trap and extract said hydrophobic substances, wherein said vehicle comprises hollow particles of hybrid aluminosilicates of imogolite or allophane type, said hollow particles having their external surface functionalized with Al—OH units and their internal surface functionalized at least in part with Si—R units, with R representing a nonhydrolyzable unit, and said one or more hydrophobic substances being selected from the group consisting of compounds containing a linear or branched aliphatic chain comprising at least 6 carbon atoms, surfactants, biocides, and methane clathrates inhibitors. 2. Method according to claim 1 , wherein said one or more hydrophobic substances is a methane clathrates inhibitor. 3. Method according to claim 1 , wherein said particles are of imogolite type with R representing a linear or branched C 1 -C 12 alkyl or alkenyl group. 4. Method according to claim 1 , wherein said particles are of imogolite type with R representing a methyl, ethyl, propyl, butyl or vinyl group. 5. Method according to claim 1 , wherein said particles are of allophane type with R representing a methyl or vinyl group. 6. Method according to claim 1 , wherein said particles are 100% hybrids. 7. Method according to claim 1 , wherein R represents a hydrocarbon unit.
