Micropore volume increases from 0.010 to 0.035 cm<sup>3</sup>/g, and surface area increases from 22.73 to 98.99 m<sup>2</sup>/g as maturity increases, indicating an enhancement in sorption capacity. As surface roughness and heterogeneity increase, fractal characteristics exhibit a positive correlation with micropores, increasing from 2.50 to 2.78. The SEM-based fractal dimensions of thermally mature samples show increasing morphological complexity, ranging from 1.958 to 1.994. Due to the constraint in accessibility of micropores, MIP-derived fractal characteristics hardly show any connection with maturity. This highlights the crucial role of thermal maturity in the formation of micropores relative to macropores. Principal Component Analysis reveals organic matter and clay minerals as two independent geological factors that primarily control the pore architecture. Together, they contribute to a 62.9 % variance in the PCA. The microporous network in organic matter signifies high potential for adsorption-driven retention of injected gases. Organic matter contributes dominantly to gas storage, while inorganic components control the gas flow pattern.

Results showed that lower initial LNG volumes increase the boil-off rate (BOR), accelerating tank pressure rise. Controlling the temperature of the stream entering the gas–liquid separator effectively adjusted methane number. The proposed cascade control strategy significantly reduced fuel losses. Over a 15-day operation period, methane and the total fuel losses reduced by approximately 13 % and 12 %, respectively, while consistently maintaining MN above 80.

Amongst the direct methods, the oxidative coupling of methane (OCM) is a potential pathway to reduce CO<sub>2</sub> emissions and can produce commodity chemicals such as ethylene, a chemical regarded as central to the petrochemical industry. Even though OCM has been studied for over four decades, the technology still has not found commercial application. Amongst the challenges regarding industrial deployment of OCM, the most significant one is the requirement of a high ethylene yield of 30 % which is currently reported to be around 20 %. Moreover, the highly exothermic nature of the process and controlling the carbon selectivity over oxides of carbon (COx) is the heart of the problem. Numerous researchers have presented promising results in terms of catalysts, reactor designs and feeding strategies for OCM.

The current paper presents an extensive review of the noteworthy attempts to achieve industrial targets for OCM.
