    This study assesses the compositional analysis and characterization of eight non-edible plant biomass identified as a potential feedstock to produce carboxymethyl cellulose. The materials' contents were ascertained by gravimetric analysis, and they were further characterized using Fourier transforms Infrared spectroscopy. According to the research, cellulose was present in substantial amounts ranging from 33 % to 41 %, with sugarcane bagasse having the highest concentration. The percentage of hemicellulose ranged from 18 % to 28 %, with corn cob having the highest percentage. Also discovered was that lignin content varied between 9 % and 22 %, with mahogany having the highest amount amongst the samples. The FTIR spectroscopic analysis of all eight samples reveals a broad band at around 3300 cm-1, which is caused by the stretching vibration of the cellulose's O-H groups. The observed peaks at 1600 cm-1 and 1500 cm-1 correlated to the hemicellulose and lignin's respective C=O and C=C stretching vibrations. Additionally, a significant sharp peak that matched the stretching vibrations in the skeleton of the pyranose ring, C-O-C, was seen at roughly 1050 cm-1. Thus, the findings of this study indicate that all eight samples can yield a respectable amount of cellulose, suggesting that these wastes may serve as feedstocks for the creation of biopolymers like carboxymethyl cellulose (CMC).

    A review on the use of carboxymethyl cellulose in oil and gas field operations
    (Cellulose, 2023-09-17) Hauwa A. Rasheed; Adekunle Akanni Adeleke; Petrus Nzerem; Olusegun Ajayi; Peter Pelumi Ikubanni; Asmau M. Yahya
    The purpose of this review is to highlight the applications of carboxymethyl cellulose (CMC) in oil and gas industries. CMC is one of the most promising cellulose derivatives and the most widely used in the drilling sector. Owing to its multifunctionality, facile, inexpensive, raw material abundance, availability, compatibility, distinctive surface property and many other disparate aspects, it is now widely used in many fields for a variety of applications, including the oil and gas industry, pharmaceuticals, food, textiles, wastewater treatment, and energy production/storage. Despite CMC’s wide applications in many fields, very few studies report its role in oil and gas operations such as drilling and completion, hydraulic fracturing, corrosion inhibition and cementing applications. As a result, this review points some of CMC’s relevance in the oil and gas industry now and in future.
