Cellulosic Aggregators for Oil Spill Remediation

The patent uses composite materials by combining vegetable-based sorbent particles with hydrophobic fatty acid modifiers (oleic acid and additional fatty acids). This creates a composite structure that maintains the environmental benefits of vegetable materials while adding the high oil sorption capacity and buoyancy characteristics of hydrophobic compounds. The fatty acids coat the vegetable particles, creating a dual-function material that resolves the contradiction between environmental friendliness and performance.

The patent changes the chemical parameters of vegetable-based sorbents by modifying them with hydrophobic fatty acids. This parameter change transforms the surface properties of the vegetable particles, dramatically increasing their oil sorption capacity and buoyancy to levels comparable with synthetic sorbents, while the underlying vegetable-based structure maintains biodegradability and environmental compatibility.

The hydrophobic fatty acid-modified vegetable particles perform self-service by simultaneously providing both sorption and coalescing functions. The hydrophobic surface naturally repels water and attracts oil, causing oil droplets to coalesce onto the particle surfaces. This eliminates the need for separate chemical herding agents, reducing toxicity while maintaining effective oil coalescing capability.

The hydrophobic fatty acid modification provides a counteracting force against water penetration and ice formation. The strong hydrophobic effect created by the fatty acid coating on vegetable particles counterweights the adverse effects of wind-driven waves and icy conditions, allowing the sorbent to maintain its oil capture effectiveness in environments where traditional sorbents would fail.
