“…Synthesis of Value-Added Chemicals. Conversion of H 2 S to value-added chemicals is another feasible way to use H 2 S. Mishra et al 6 used the IL of trihexyltetradecylphosphonium chloride (THTDPC) as the catalyst for the utilization of H 2 S to synthesize bis(2-phenylethyl) sulfide (PES). More specifically, H 2 S was first absorbed into aqueous MDEA, which was followed by the reaction of H 2 S-enriched MDEA with 2-bromoethylbenzene (2-BEB) to produce PES in the presence of THTDPC.…”

“…A trace amount of H 2 S is poisonous for many metal catalysts . H 2 S, on the other hand, is an important feedstock of the productions of sulfur, hydrogen, and some value-added metal sulfides and thio-organic chemicals, such as bis(2-phenylethyl) sulfide . Therefore, both removal and further utilization of H 2 S from gas streams are all of great importance for human health, environmental protection, downstream operation, and resource reutilization.…”

Hydrogen sulfide (H2S) is highly toxic and one of the problematic impurities in industrial gas streams, calling for H2S removal down to single-digit ppm levels to protect health and environment, and not to harm to the downstream processes. Here, we discuss the recent developments and challenges of current H2S removal technologies. Furthermore, we present a comprehensive review of H2S removal in ionic liquids (ILs), IL-based solvents/adsorbents/membranes, and deep eutectic solvents (DESs) due to their unique advantages. We analyze theoretical studies to better understand the microscopic details behind H2S removal. We discuss new research on IL/DES-based H2S removal processes from an industrial perspective. Finally, we summarize the utilization of H2S in IL/DES-based systems for the recovery of sulfur and hydrogen, and synthesis of value-added chemicals. This review will provide both general and in-depth knowledge of the achievements, difficulties, and research priorities in developing novel ILs/DESs for efficient and sustainable H2S removal and utilization.

As a highly toxic gas, H 2 S is conventionally removed via a chemical absorption process. However, the high regeneration energy is still a challenge. 1,5-Diazabicyclo[4.3.0]non-5-ene (DBN)/polyethylene glycol dimethyl ether (NHD) solution was developed as an efficient nonaqueous phase change absorbent for the removal of H 2 S with low energy consumption. A homogeneous DBN/NHD solution turns into two immiscible liquid phases upon the absorption of H 2 S, which results from the higher polarity of the product compared to that of the original solution. The loading capacity of H 2 S can reach 0.16 g•g −1 solvent even under a H 2 S partial pressure of 10 kPa at 30 °C. After absorption, more than 94% of the absorbed H 2 S is concentrated in the lower phase, which can be regenerated at 90 °C with an energy consumption estimated to be 1.69 GJ•t −1 H 2 S. The regeneration energy is 58% lower than that of 30 wt % aqueous solution of N-methyldiethanolamine. 81% of the initial H 2 S loading was maintained after 4 absorption−desorption cycles. In addition, the selectivity of DBN/NHD solution to absorb H 2 S from N 2 containing H 2 S and CO 2 or from N 2 containing H 2 S and CH 4 was investigated. It shows that the selectivity increases with the increase in the volume ratio of H 2 S to CO 2 , which can be as high as 27.8 when the ratio is 1:1. CH 4 cannot be absorbed in the DBN/NHD solution in the presence of H 2 S and N 2 .

“…It is known that long-time exposure to CO leads to decreased oxygen supply to body organs, resulting in unconsciousness and death . The presence of trace H 2 S and CO in membrane fuel cells and metal catalysts leads to catalytic poisoning. , Despite the numerous problems such as those discussed above, H 2 S is an essential raw material for manufacturing thio-organic chemicals, metal sulfides, hydrogen, and sulfur . CO is a crucial precursor for synthesizing widely used compounds like amide, menthol, and acetic acid .…”
