摘要:
The present invention relates to the use of (poly)oxymethylene-dialkyl ethers as agents for capturing carbon oxides, CO and/or CO 2 . The invention also relates to the method for capturing carbon oxides using at least one absorption agent selected from among said (poly)oxymethylene-dialkyl ethers.
摘要:
The present invention relates to a method for preparing carbon fibrils and/or nanotubes from a carbon source integrated in the catalyst used for their preparation and a source of hydrocarbonated gas, as well as to the catalyst material and to the corresponding method. The catalyst material for preparing mono- or multi-leaved carbon fibrils and/or nanotubes includes one or more given multivalent transition metals and a hydrocarbonated solid organic substrate.
摘要:
The subject of the present invention is a process for synthesizing nanotubes, especially carbon nanotubes, by decomposition of a gas source, at a temperature ranging from 400 to 1200 °C in a reactor, by bringing it into contact with at least one (one or more) multivalent transition metals, the transition metal(s) being supported on a support having a specific surface area determined by the BET method of greater than 50 m2/g, especially within the range from 70 m2/g to 400 m2/g. The support according to the invention is especially an inorganic support, for example an alumina having a multimodal porosity. The subject of the invention is also the nanotubes thus obtained and their use for improving the mechanical and/or electrical and/or thermal properties of materials, especially polymeric materials.
摘要:
The present invention relates to a method for capturing carbon oxides, in particular for recovering carbon oxides from an industrial facility, and specifically to a method for capturing CO 2 contained in a gas flow with a view to storing said CO 2 , said method including placing said gas flow in contact with a solvent including an organometallic compound, such that said solvent captures said carbon oxides to form an enriched solvent. The present invention relates in particular to the use of said capture method in post-combustion or pre-combustion processes.
摘要:
The invention relates to a method for manufacturing a composite material including tin oxide particles and a fibrillar carbon material, consisting of synthesising tin hydroxide particles obtained from a tin salt by precipitation/nucleation in a water-alcohol medium, in the presence of the fibrillar carbon material and an acid, the fibrillar carbon material being nanotubes, carbon nanofibres, or a mixture of the two. The invention can be used for the production of negative electrodes for lithium-ion batteries.
摘要:
The invention relates to a simple and economic method for treatment of carbon nanotubes, in particular, for the modification of the surface thereof by functionalisation for improving the compatibility thereof with polar media, such as certain polymers, resins or solvents. The invention further relates to nanotubes treated thus and the use thereof in the electronic, electromechanical and mechanical fields in which the above represent an advantageous replacement for untreated carbon nanotubes.
