“…Increasing the oxygen flow rate can increase the ozone capacity, as more oxygen molecules are available for ozone formation. However, excessive flow rates may result in a lower ozone capacity due to the formation of less reactive ozone species or the generation of unwanted byproducts (Yulianto et al, 2019). Furthermore, the reaction time can significantly impact the ozone concentration and lead to higher energy efficiencies.…”

Oil palm fruit mesocarp (OPFM) is a solid by-product containing cellulose, potentially serving as a raw material for biofuel. The cellulose content of this solid by-product can be extracted through delignification. Therefore, this study aimed to investigate the application of ozone for OPFM delignification to break down lignin bonds in the material. During the analysis, ozonolysis delignification was influenced by particle size, oxygen flow rate, and reaction time. Ozone flowrate analyzed using the Iodometric method. Cellulose, hemicellulose, and lignin content of raw material and treated samples were analyzed using the α -cellulose, γ -cellulose, and the Kappa method. The results showed that by using a particle size of 100 mesh, and a flow rate of 2 Lmin -1 for 15 min, ozone degraded 42.03% lignin, 15.89% hemicellulose, and concentrated 62.85% cellulose. SEM and FTIR results showed the removal of hemicellulose and lignin from OPFM with ozonolysis delignification. Furthermore, XRD analysis showed the crystallinity degree of the high cellulose yield.

“…Here, the influence of input power on ozone formation at constant CH 3 OH concentration (260 ppm) and residence time (3.3 s) in dry and humidified air carrier gases were studied. The O 3 concentrations from the outlet of the DBD reactor were measured using the standard KI solution method as described by Yulianto et al 50 The O 3 concentration as a function of input power using dry and humidified air carrier gases is presented in Fig. 9 .…”

This study developed an ozone generator of a double co-axial cylindrical dielectric barrier discharge system with air, argon, and oxygen as the working gases. The discharge was produced by using a high voltage power supply of 0 - 18 kV and a line frequency of 50 Hz. The flow rate of air, argon, and oxygen was varied from 1 to 6 L/min. A comparison of O3 generation in air, argon, and oxygen using brass as a central electrode was conducted and it was found that O3 concentration was higher in the case of oxygen than in the air and in argon gases environment for given fixed discharge time, applied voltage, and diameter of the brass electrode. This study revealed that the concentration of ozone increased along with the increase in the applied voltage for constant discharge time and gas flow rate. The O3 concentration also increased with the increase in the discharge time at fixed applied voltage and gas flow rate; however, the concentration decreased with the increase in the gas flow rate at fixed discharge time, applied voltage, and diameter of the electrode. A small reactor with a large inner electrode generated a high concentration of O3. Yet, a reactor with a small diameter, there seemed to have an optimum inner electrode diameter. The glass tube reactor of the internal diameter of 18 mm and the brass electrode of diameter 8 mm were utilized in this study. The ozone concentration was higher for oxygen as feed gas than both in the air and in argon and the O3 concentration was also higher in the air than in argon at fixed discharge time, applied voltage, and diameter of ozone generator. HIGHLIGHTS Ozone concentration increases with increasing applied voltage and discharge time but concentration decreases with increasing gas flow rates Low cost ozone can be produced in DBD reactor at atmospheric pressure Oxygen can be used as feed gas to generate high concentration of ozone than other gases inside DBD generator Optimization of central electrode diameter and gap space inside DBD reactor can help to increase ozone concentration, yield, and efficiency Proper choice of central high voltage electrode also can play the important role for the generation of ozone in DBD chamber GRAPHICAL ABSTRACT
