“…Interestingly, the use of microsecond pulses (pulse width superior to 10 µs) seems to be very efficient, with a coefficient of 1.70. However, only three papers in our review use this kind of signal [20,24,28]. More data would be needed to confirm this trend.…”

Non-thermal plasma is an emerging alternative for removing VOC from polluted air streams. This technique has been studied in laboratory for more than twenty years and experimental data is abundant. However, mostly qualitative information has been obtained from that data and no model has been developed for predicting the treatment performance from a given set of parameters. In this paper, we establish such a model, based on experimental data extracted from 69 scientific publications. This model, obtained through a linear regression, uses both quantitative and qualitative variables to predict the energy yield of the treatment. In 80 % of the data points, the measured energy yield lies between 0.6 and 1.75 times the predicted value. We also used the model to evaluate quantitatively the impact of several parameters of the treatment, such as the initial concentration, the presence of a catalyst or the reactor type. Being so, the model presented here is an invaluable tool for both scientists and engineers interested in the treatment of VOC by non-thermal plasma.

“…The reaction mechanism of the cracking process of model compound, i.e., n -decane, in the plasma system without catalyst was postulated by several researchers. , The decomposition/cracking of n -decane includes the cleavage of C–C and C–H bonds. However, the first mechanism of this cracking process is the dehydrogenation of n -decane, including C–H scission and H-abstraction (see Figure ), resulting the formation of the •C 10 H 21 free radical . However, the chemical bonding energy (bond dissociation energy) of the C–H bond (4.3 eV) is higher than that of the C–C bond (3.6 eV), for which the β-C–C bond is the weakest, followed by the γ-C–C bond .…”

As energy demands increase and fossil fuels resources decrease, a renewable energy must be developed to supply energy demand. Biofuels from vegetable oils has great potential to help supply that energy demand, since biofuels is renewable energy. Biofuels from vegetable oils can be produced through the cracking process of vegetable oils. In this paper, a comprehensive mini review on cracking processes using advanced technologies, especially plasma-assisted catalytic cracking, was reported. The catalytic cracking is the most developed process,because of high selectivity in biofuels production, by introducing base and/or acid catalysts. The latest advanced cracking process technology is plasma-assisted catalytic cracking in addition to microwave-assisted cracking process. Plasma discharge has an important role in assisting electron excitation in the covalent bond of reactant molecules, i.e., breaking C−C, CC, etc., so that the cracking process can be conducted easily. Several plasma reactor designs have been proposed by previous researchers; however, the dielectric barrier discharge (DBD) plasma reactor is the most preferred design. Several process parameters that affected the DBD plasma reactor performance, such as discharge gap, feed flow rate, applied voltage, presence of catalysts, and reactor temperature, were addressed. Even though the plasma-assisted catalytic cracking show high potential alternative technology in vegetable oil conversion to biofuels, several drawbacks, which are addressed in this paper, must be considered in the cracking process. Therefore, this mini review is expected to bring the researcher's mindset to innovate the cracking process to be efficient as possible.

“…Wang et al [13] used synchrotron vacuum ultraviolet (VUV) ionization mass spectrometry and detected the decomposition products of iso-propyl alcohol under the action of plasma and found a great number of free radials and reactive intermediates. Yao et al [14] processed n-C10H22 using coaxial dielectric-barrier discharge (DBD) with a discharge gap of 2.6 mm and micromolecular hydrocarbons were detected in the products. Prieto et al [15] adopted a parallel-plate electrode for processing static heavy oils and detected a great amount of hydrogen as a result of long retention time.…”

A highly-integrated experimental system for plasma decomposition of fuels was built. Experiments were conducted and confirmed that macromolecular chain hydrocarbons were cracked by large-gap dielectric barrier discharge under the excitation of a microsecond-pulse power supply. Alkanes and olefins with a C atom number smaller than 10 as well as hydrogen were found in the cracked products of n-decane (n-C10H22). The combination of preheating and plasma decomposition had strong selectivity for olefins. Under strong discharge conditions, micromolecular olefins were found in the products. Moreover, there was a general tendency that micromolecular olefins gradually accounted for higher percentage of products at higher temperature and discharge frequency.
