“…[6] However, the first process often yields poor-quality light products, resulting in the production of lowvalue coke or asphalt-like materials. [7] Conversely, hydrogen addition methods, such as hydrotreating and hydrocracking, involve introducing H-active species to cracking heavy oil molecules with the assistance of a catalyst under high hydrogen partial pressure. [8] While hydrogenation can mitigate coke formation and enhance the quality of light products, its implementation is challenged by the high cost associated with the production process, especially from the extreme endothermic reforming of natural gas, such as CH 4 .…”

Non‐thermal plasma (NTP) catalysis, mirroring the trend towards non‐conventional electron‐mediated molecular activation, unfolds novel routes for chemical reactions. Operating at ambient pressure, lower temperatures, and energized by electricity that can powered by renewable sources, NTP offers a cost‐effective and efficient means of sustainable fuel production. This approach has the potential to revolutionize the oil and gas industry, meeting current energy demands while circumventing the challenges posed by conventional thermal catalysis processes, thereby enhancing environmental sustainability and energy security. Through an exploration of the synergistic effects between plasma, catalysis, and hydrocarbon molecules, this concept paper emphasizes the significant advancements made in in‐liquid plasma catalysis strategies for fuel production from heavy oil upgrading. We also provide insights into the heterogeneous catalyst design and the role of plasma gas as an additional catalyst for achieving efficient and sustainable energy solutions. The prospects of in‐liquid plasma catalysis, emphasizing its transformative role in shaping the energy future, are also discussed.

“…Petroleum refineries, with a production capacity of 105,000 drums per day, produce approximately 50 tons of oily sludge per year . Globally, more than 1 × 10 7 tons of oily sludge is produced per year. − Alkane, cycloalkane, and polycyclic aromatic hydrocarbon (PAH) constitute the TPH fractions of oily sludge and impart toxicity to the surrounding environment, humans, and animals. ,− Moreover, seepage of oil from oily sludge stored in pits contaminates subsurface soil and aquifers . The Research Conservation and Recovery Act (RCRA) and the United States Environmental Protection Agency (USEPA) have considered such oily waste as hazardous waste. , There are several reports indicating the application of bioremediation approaches for treating oily sludge. ,− It would be preferable to recover some valuable byproducts along with their treatment.…”

Though bioremediation of hazardous petroleum refinery waste (oily sludge) has been practiced for the last few decades, the present study proposes to obtain polyhydroxyalkanoate (PHA)-based bioplastic polymer from it as a valuable byproduct parallel to its treatment. In the present study, nine fastgrowing and sodium benzoate degrading bacterial strains belonging to the genera Achromobacter, Pseudomonas, Acinetobacter, Ochrobactrum, and Pannonibacter were found to be PHA-positive. The screened bacterial cultures showed total petroleum hydrocarbon (TPH) degradation in the range of 31% to 91% from 1% oily sludge containing medium and could accumulate PHA in the range of 50% to 92%. The Fourier Transform Infrared (FTIR) interferogram of extracted PHA represented PHA-related functional groups, while proton nuclear magnetic resonance ( H NMR) spectra showed chemical shifts corresponding to a −CH 3 of 3HB (0.88 ppm) and 3HV (1.5 ppm) monomers, thus confirming it as poly(3-hydroxybutyrate-co-3hydroxyvalerate) or P(3HB-co-3HV). The thermal features of extracted P(3HB-co-3HV) such as low melting temperature (T m ) and low % crystallinity (%Xc) are industrially more significant. Ochrobactrum ciceri strain AWIS01 was found to be the most efficient organism, showing 0.720 g/L P(3HB-co-3HV) production while degrading 90.06% TPH when 1% oily sludge was provided as the sole source of carbon. In the future, such bacteria can be used to produce bioplastic polymer from oily sludge.

“…Syngas is produced from pyrolysis/gasification using different materials as inputs. The great advantage of thermal processing is its versatility, being capable of treating fossil sources such as oil sludge, a viscous residue derived from crude extraction and processing, heavy oil, coal, plastics and also renewable sources such as biomass, manures, and organic wastes in general [23][24][25][26][27][28]. The gas produced has a low volumetric energy density mainly due to H 2 and CO.…”

The fermentation of syngas is an attractive technology that can be integrated with gasification of lignocellulosic biomass. The coupling of these two technologies allows for treating a great variety of raw materials. Lignin usually hinders microbial fermentations; thus, the thermal decomposition of the whole material into small molecules allows for the production of fuels and other types of molecules using syngas as substrate, a process performed at mild conditions. Syngas contains mainly hydrogen, carbon monoxide, and carbon dioxide in varying proportions. These gases have a low volumetric energy density, resulting in a more interesting conversion into higher energy density molecules. Syngas can be transformed by microorganisms, thus avoiding the use of expensive catalysts, which may be subject to poisoning. However, the fermentation is not free of suffering from inhibitory problems. The presence of trace components in syngas may cause a decrease in fermentation yields or cause a complete cessation of bacteria growth. The presence of tar and hydrogen cyanide are just examples of this fermentation’s challenges. Syngas cleaning impairs significant restrictions in technology deployment. The technology may seem promising, but it is still far from large-scale application due to several aspects that still need to find a practical solution.
