“…Both series of values are depicted in Fig. 8 [15] and at 3.05 and 4.43 bar reported in reference [30]. The continuous line correspond to the amount of H 2 S solubilized in liquid sulfur without forming polysulfanes [23] polysulfanes is several orders of magnitude higher than that of the corresponding sulfur chains.…”

“…Figure 7 shows the solubility of H 2 S in liquid sulfur as reported by Fanelli [15], starting from the melting point of sulfur (125°C at 1 bar). The solubility of H 2 S in liquid sulfur increases with increasing temperature and passes through a broad maximum between 200 and 385°C.…”

“…In order to explain the chemistry observed, the complex composition of gaseous and liquid sulfur [15,16] needs to be discussed briefly first. Figure 5 shows the composition of liquid and gaseous sulfur equilibrated at 1.13 bar.…”

“…Such variations in composition cause major changes in the physicochemical properties [16]. The most pronounced effect is that the viscosity increases rapidly by two orders of magnitude [15]. On the other hand, at temperatures above 250°C, liquid sulfur becomes highly reactive due to a significant presence of S 3 , thiozone and other small agglomerates [24,25].…”

The synthesis of COS from CO, CO 2 and liquid sulfur in the presence and absence of hydrogen was explored. The reaction of H 2 with liquid sulfur produced H 2 S and polysulfanes, which increase the reactivity of liquid sulfur and provide alternative complementary reaction routes for the formation of COS. The reaction from CO 2 proceeds by forming CO as intermediate. Elevated pressure favors formation of COS from both carbon oxides due to the increasing residence time and the saturation of gases in the liquid. Above 350°C, the solubility of H 2 S in sulfur and the hydrogenation of COS limit the conversion of CO. The approach provides a highly efficient method for the preparation of COS under mild reaction conditions, without using a catalyst or water adsorbents.

“…Mole fractions of CO increased to a maximum value as CO 2 decomposed to release oxidizer into the reactor (reactions 29 and 30 [5,14,16]). However, decrease in CO mole fractions further downstream the reactor is attributed to COS and CS 2 formation as well as possible recombination of CO to form CO 2 [35][36][37][38][39][40]. Both COS and CS 2 mole fractions increased monotonically until they reached a maximum value.…”
