The mobile electrode (anode) was then moved along 3.1.2. Reactor Experimental Process an axial axis, utilizing a positioning method, till it contacted the fixed electrode (cathode). The H2 and CO reactant gases (both 99.999 mol purity)), acquired from Afrox (Durban, South Africa), have been mixed to form syngas with a H2/CO ratio of 2.two:1. Composition evaluation using a Shimadzu 2010 Plus gas chromatograph (Kyoto, Japan), before experiments, showed that only methane (up to 15 ppm) was present as an impurity within the syngas. Prior to each experiment, the reactor was purged with helium and evacuated usingCatalysts 2021, 11,31 ofElectrode continuity was confirmed by a multimeter. Direct tip-to-plane speak to of your electrodes was compulsory so as to decrease the gas resistivity and overcome the restrictions enforced by Paschen’s Law under the low current (450 mA) and high pressure (1 MPa) operating conditions. Subsequent to electrode speak to, the high voltage DC energy supply was switched on. The energy supply was pre-set to the needed supply present (between 250 and 450 mA) and ignition voltage (eight kV). As soon as the power supply was activated, the mobile anode was quickly retracted from the fixed cathode, instantaneously forming a luminous arc discharge. The anode was retracted until an inter-electrode gap of 1 mm (among the electrodes) was acquired. The discharge was maintained at this electrode gap, at which syngas therapy proceeded for a pre-determined period of either 10 or 60 s. After this discharge period, the energy supply was switched off, instantaneously extinguishing the arc discharge. As a security measure, an insulated copper wire was utilized to transmit residual charge in the arc discharge reactor to ground. Thereafter, the goods have been sampled from the reactor and analyzed off-line applying a Shimadzu 2010 Plus Gas Chromatograph (Kyoto, Japan). The GC was fitted with a thermal conductivity detector (TCD), Goralatide custom synthesis calibrated to detect CO and H2 , plus a flame ionization detector (FID), calibrated to detect.
