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.

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).

There is a lack of information about the detailed characterization of biomass of Nigerian origin. This study presents a comprehensive characterization of six biomass, groundnut shells, corncob, cashew leaves, Ixora coccinea (flame of the woods), sawdust, and lemongrass, to aid appropriate selection for bio-oil production. The proximate, ultimate, calorific value and compositional analyses were carried out following the American Standard for Testing and Materials (ASTM) standards. Fourier transform infrared spectroscopy, thermogravimetric analysis, scanning electron microscopy with energy-dispersive X-ray spectroscopy, and X-ray fluorescence were employed in this study for functional group analyses, thermal stability, and structural analyses. The H/C and O/C atomic ratios, fuel ratio, ignitability index, and combustibility index of the biomass samples were evaluated. Groundnut shells, cashew leaves, and lemongrass were identified as promising feedstocks for bio-oil production based on their calorific values (>20 MJ/kg). Sawdust exhibited favorable characteristics for bio-oil production as indicated by its higher volatile matter (79.28%), low ash content (1.53%), low moisture content (6.18%), and high fixed carbon content (13.01%). Also, all samples showed favorable ignition and flammability properties. The low nitrogen (<0.12%) and sulfur (<0.04%) contents in the samples make them environmentally benign fuels as a lower percentage of NOx and SOx will be released during the production of the bio-oil. These results are contributions to the advancement of a sustainable and efficient carbon-neutral energy mix, promoting biomass resource utilization for the generation of energy.

This study explores the utilization of eight readily available agricultural waste varieties in Nigeria—sugarcane bagasse, corn husk, corn cob, wheat husk, melina, acacia, mahogany, and ironwood sawdust—as potential sources of cellulose. Gravimetric analysis was employed to assess the cellulose content of these wastes, following which two selected wastes were combined based on their cellulose content and abundance to serve as the raw material for the extraction process. Response Surface Methodology, including Box-Behnken design, was applied to enhance control over variables, establish an optimal starting point, and determine the most favorable reaction conditions. The cellulose extracted under various conditions was comprehensively examined for content, structure, extent of crystallinity, and morphological properties. Characterization techniques such as X-ray Diffraction, Scanning Electron Microscopy, and Fourier Transform Infrared Spectroscopy were employed for detailed analysis. Compositional analysis revealed sugarcane bagasse and corn cob to possess the highest cellulose content, at 41 ± 0.41% and 40 ± 0.32% respectively, with FTIR analysis confirming relatively low C=C bond intensity in these samples. RSM optimization indicated a potential 46% isolated yield from a hybrid composition of sugarcane bagasse and corn cob at NaOH concentration of 2%, temperature of 45 °C, and 10 ml of 38% H2O2. However, FTIR analyses revealed the persistence of non-cellulosic materials in this sample. Further analysis demonstrated that cellulose isolated at NaOH concentration of 10%, temperature of 70 °C, and 20 ml of 38% H2O2 was of high purity, with a yield of 42%. Numerical optimization within this extraction condition range predicted a yield of 45.6% at NaOH concentration of 5%, temperature of 45 °C, and 20 ml of 38% H2O2. Model validation confirmed an actual yield of 43.9% at this condition, aligning closely with the predicted value. These findings underscore the significant potential of combinning and utilizing agricultural wastes as a valuable source of cellulose, paving the way for sustainable and resource-efficient practices in various industrial applications.
