摘要

The drive for affordable, sustainable, high-performance materials in the operation of oilfields has never been greater. Conventional oilfield chemicals usually perform inadequately at extreme temperatures and pressures, and they raise environmental concerns, raising a clear need for greener alternatives. Nanocellulose fits this niche nicely-a renewable, biodegradable material with outstanding mechanical and surface properties that holds real promise in this arena. The objective of this research is to focus on nanocellulose derived from corn stalks-a very abundant agricultural waste. Accordingly, the methodology began with drying and mechanical reduction in size, then passing the material through a series of sieves to obtain fine particles. Pretreatment consisted of alkaline digestion using NaOH to remove hemicellulose and hydrogen peroxide bleaching to remove lignin to yield high-purity cellulose. Acid hydrolysis with 64% sulfuric acid was used to harvest nanocellulose, and the product was washed, centrifuged, and sonicated to form a stable colloidal suspension. Characterization by FTIR, XRD, and DLS confirmed the effective removal of non-cellulosic components, showed high crystallinity, and presented nanoscale particle dispersion. Finally, it appears that nanocellulose, derived from corn stalks, can be efficiently produced by a relatively simple process and exhibits properties very suitable for oilfield chemical applications. With its high surface area, crystalline structure, and ‘green’ profile, it represents an excellent candidate to enhance drilling fluids, inhibit scale, and support other petroleum engineering applications. This experimental work shows the involvement of agricultural-waste-based nanocellulose in new generation oil and gas industries, having their capacity in sustainable chemical development for performance increment. The addition of nanocellulose shows structural and colloidal characters that is useful for future analysis in petroleum industry chemical systems, like drilling fluids, cementing fillers and scale deposition solutions.
