“…In the steam reforming process of RCOG, the key involved chemical reactions are shown in Table 2 [23,24]. In the presence of CO 2 sorbent, calcium oxide (CaO) was selected as CO 2 sorbent, due to the wide application of Cabased sorbent in the sorption-enhanced steam reforming process [20,[25][26][27][28][29].…”

“…The above results were mainly attributed to the CO 2 adsorption reaction [Eq. (24)] occurring. CO 2 adsorption displaced the equilibriums of the steam reforming reactions and the WGS reaction to the directions of hydrogen production.…”

The steam reforming processes of raw coke oven gas (RCOG) for hydrogen production without and with CO 2 adsorption were studied via the thermodynamic analysis. Ordinary pressure (1 bar) was found as the best reaction pressure for RCOG steam reforming. The hydrogen yield increased with the increases in temperature and S/RCOG ratio and then flatted out around 160 mol per 100 mol RCOG at the temperature above 700°C and S/RCOG ratio above 0.8, yet with hydrogen concentration of just about 70 %. After the addition of CaO as CO 2 sorbent, the hydrogen yields increased on the whole as the CaO/C ratio and S/RCOG ratio rose, and the temperature range with the hydrogen yield around 160 mol and even higher was widened and moved to low temperature. The optimal conditions of sorption-enhanced RCOG steam reforming for hydrogen production were S/RCOG ratio above 0.8, CaO/C ratio above 2.0 and the temperature from 550 to 700°C, with the hydrogen yield and concentration reaching around 160 mol and over 90 %, respectively.

“…They compared the equilibrium predictions to experimental data obtained using a first generation plasmatron reformer operated on diesel fuel and found that the efficiency of the reformer was much lower than the theoretical maximum. Nunnally et al [15] studied the conversion of a simulated syngas containing vaporized toluene and naphthalene in a non-equilibrium gliding arc plasma reformer and showed significant improvement over previous work in gliding arc for tar reforming. Van Oost et al [16] used a low-mass flow rate DC plasma torch with gasewater stabilized arc to study the thermal decomposition of crushed wood.…”

“…The conversion of gaseous hydrocarbons such as methane and propane into hydrogen and syngas by reforming or into other organic species such as alcohols and acids by oxidative conversion has been studied using a wide range of plasma systems [1][2][3][4][5]. Significantly less attention has been paid to larger hydrocarbons, such as oils.…”

Abstract:The degradation of liquid dodecane was studied in a gliding arc discharge (GAD) of humid argon or nitrogen. A batch or recirculating configuration was used. The products in the gaseous and liquid phase were analysed by infrared and chromatography and optical emission spectroscopy was used to identify the excited species in the discharge. The best degradation performance comes from the use of humid N 2 but a GAD of humid argon produces fewer gas-phase products but more liquid-phase end-products. A wide range of products such as heavier saturated or unsaturated hydrocarbons both aliphatic and aromatic, and oxidation products mainly alcohols, but also aldehydes, ketones and esters are produced in the liquid-phase. The recirculating treatment mode is more effective than the batch mode increasing the reactivity and changing the product selectivities. Overall, the study shows promising results for the organic liquid waste treatment, especially in the recirculating mode.
