“…[9] Biodiesel is typically derived from various oils and fats, including vegetable, animal, waste, and nonedible oils. [10,11] Catalysts used in this process are classified into homogeneous and heterogeneous groups. A catalyst is considered homogeneous if it is in the same phase as the reactants, while it is categorized as heterogeneous if the reactants and catalyst are in two different phases.…”

“…In this process, high-energy electrons function as an electrocatalyst, interacting with molecules and atoms to generate electrons, photons, ions, and secondary radicals through collisions. [10,18] Dielectric barrier discharge (DBD) plasma, also known as cold plasma or nonthermal plasma, offers the benefits of reaction selectivity and high-energy efficiency. In addition, it is expected that by using this technology, the reaction time will be reduced due to the role of high-energy electrons, and the separation process of glycerol will be easy because it is not formed.…”

“…Also, high-energy electrons are expected to replace the catalyst during transesterification reactions. [10,17] In the cold plasma method, reaching a high conversion percentage requires a long exposure time. This study combines cold plasma and oscillatory methods to achieve improved biodiesel conversion rates, shorter reaction times, and reduced reactor dimensions.…”

While fossil fuel resources are limited, the increasing demand for energy in the industrial and transportation sectors has led to using renewable fuels. This study aims to improve biodiesel production from sunflower oil by combining cold plasma and oscillatory systems through a transesterification process. The four main operational variables are examined, such as molar ratio (MR) (1:6–1:12), catalyst concentration (CC) (0.5–1.25 wt%), plasma exposure time (PET) (25–75 s), and residence time (RT) (30–90 s). The smooth periodic constriction reactor's physical attributes, including the diameter of the tube (D), the diameter of the constricted region (d0), and the distance between baffles (l), as well as the properties of the cold plasma system, are determined. The data analysis presents that PET, RT, CC, and MR have the greatest effect on efficiency. This optimization indicates that by exposing the reaction mixture to plasma for 59.99 s, adding 1.09% by weight of the catalyst, and with a MR of 7.17 in 86.43 s, biodiesel with a conversion percentage of 94.75% is produced. The results show that the optimum point matches with EN 14214 standard.
