## 1 Introduction  
Liquefied petroleum gas (LPG) is mainly composed of propane and butane gases, which are produced generally from the wet natural gas purification (55%) and the refining process of crude oil (45%). While LPG is used extensively for heating and cooking, its reforming is required for vehicle applications by a low energy output. A solution is to reform LPG towards hydrogen generation as a clean fuel and different methods such as steam and oxidative reforming techniques are used [1]. [PERSON] [2] studied the hydrogen production from the LPG through oxidative steam reforming with bimetallic catalysts. Moreover, in the performed experiments by [PERSON] et al. [3], the LPG steam conversion reactions on the nickel catalysts supported by four different zeolites (H-Y, Na-Y, HZSM5, and ferrierite) were examined. The type of support and the specific surface area significantly affected the catalyst activity and selectivity; however, the Ni/Na-Y catalyst exhibited the highest surface area (696.4 m\({}^{2}\)/g) and a low degree of coke formation. Hence, the stability of the LPG steam reforming process was increased. Thus, the highest LPG conversion of about 95.7% and H\({}_{2}\) yield of 48.6% was observed for the Ni/Na-Y catalyst. Using a thermodynamic analysis, [PERSON] et al. [4] investigated the operational conditions of molecular hydrogen production through the LPG steam and oxidative conversion process. The performance of LaNiO\({}_{3}\) as a catalyst precursor was analyzed based on the thermodynamic equilibrium predictions. The H\({}_{2}\) formation increased at high temperatures and water concentrations, while the coke production decreased gradually. [PERSON] et al. [5] performed a parametric study on the auto-thermal LPG reforming. The effects of temperature and the ratios of steam and O\({}_{2}\) to carbon (S/C and O\({}_{2}\)/C) along with the performance indicators of the LPG conversion extent, catalyst coking, and sulfur poisoning were studied. In addition, [PERSON] et al. [6] used the auto-thermal reforming for propane conversion where the water-gas shift and preferential oxidation occur when water is added to the system. Hence, the temperature in the hot and cold streams can be controlled in a balanced condition. So far, the electrical plasma discharges have recently been used for the conversion of gases such as methane, ethane, acetylene, and other hydrocarbons to hydrogen and syngas [7; 8]. [PERSON] et al. [9] converted propane gas to hydrogen with a low CO\({}_{x}\) production using an atmospheric pressure cold plasma system. They used argon to increase the ionization rate in the plasma discharge medium of the system. The discharge input power joined with the residence time of propane gas in the discharge medium of the system had a significant effect on the propane conversion. Hence, the hydrogen selectivity and efficiency of energy conversion were increased. In a theoretical work by [PERSON] et al. [10], a plasma discharge system which was based on dielectric barrier discharge (DBD) at the gas pressure of 600 torr was used for conversion of the pure methane gas. The applied voltage was assumed to be sinusoidal and the temporal variations of the discharge parameters were examined. While their numerical findings were compared with experimental works, it was found that the dielectric capacitance plays a critical role in the methane conversion and H\({}_{2}\)/CH\({}_{4}\) ratio. [PERSON] et al. [11] implemented a micro-plasma for conversion of the liquid fuel methanol and five different experiments showed that the conversion within the microchannel reached about 100%. The results of the experiments on the variations of the input electrical power, flow rate, and concentration were validated by a numerical model. Meanwhile, the continuous production of hydrogen gas along with carbon black from CH\({}_{4}\) using a specific reactor based on the direct current (DC)-spark discharge plasma at atmospheric pressure was experimentally examined by [PERSON] et al. [12].
