Nanowire Extractor for Selective Algae Oil Adsorption

The patent employs nanowire materials with controlled porosity and specific surface area to adsorb oil from microalgae. The porous structure provides high surface area for oil adsorption, enabling efficient extraction without chemical substances. The nanowire morphology with tunable pore size allows selective adsorption of oil components while maintaining environmental friendliness and reducing extraction costs.

The patent develops composite nanowire materials combining different metal oxides or ceramics to achieve optimal oil adsorption performance. The composite structure leverages synergistic effects of constituent materials to enhance oil extraction efficiency while maintaining cost-effectiveness and environmental compatibility, replacing traditional chemical extraction methods.

The patent modifies the local properties of nanowire materials by controlling surface chemistry, pore size distribution, and surface functional groups at specific locations. This local quality optimization enables selective adsorption of algae oil molecules while rejecting water and other components. The surface modification creates specific binding sites that match the size and chemical characteristics of oil molecules.

The patent systematically adjusts critical parameters including nanowire diameter, pore size, surface area, and surface chemistry to achieve optimal selective adsorption. By changing these parameters, the material's affinity for oil molecules is enhanced while maintaining size compatibility with algae oil molecules, improving both adsorption capacity and selectivity.

The patent employs disposable nanowire adsorbents that can be used once for oil extraction and then discarded or regenerated. These nanowire materials are designed to selectively adsorb oil while repelling water, avoiding the water absorption problem of biological fibers. The materials can be easily separated from the extracted oil and do not cause secondary pollution when disposed of.

The patent uses hydrophobic porous nanowire materials with controlled pore structures that preferentially adsorb oil molecules while excluding water. The porous structure provides high oil capacity while the hydrophobic surface chemistry prevents water adsorption, eliminating the secondary pollution issue associated with biological fibers that absorb both oil and water.
