“…Decomposition of H 2 S occurs at room temperature with hydrogen evolution to the gas phase ( Figure 7) and sulfur accumulation in solution with efficiency towards H 2 S utilization of 97.9% (Table 2) [40]. Efficiency of H 2 S decomposition can be improved to 99.6% in the periodical regime (Table 3) [20], when, after solution saturation with H 2 S, the reaction is allowed to be completed in a closed system.…”

“…Similar to the biological processes of H 2 S assimilation with sulfur bacteria in aqueous medium, the efficiency of H 2 S decomposition can be essentially improved (compared to the gas phase process) when solid catalyst is being immersed into a solvent capable of readily dissolving both hydrogen sulfide and the final products of the reaction (5) [20,40]. The scanning electron microscope images of white globular sulfur obtained from H 2 S on the metal catalyst immersed into water [20,24].…”

“…Compared with the source control, the end‐of‐pipe control is much more realistic and available, since our modern industry is still powered by fossil fuels and collecting the pollutants is much easier than purifying the fuels . However, the traditional strategies to eliminate air pollutants, such as chemical/physical absorption, catalytic decomposition and so on, usually provide ecological benefits, but no economic benefits, which hampers the widespread application of these techniques . These realities are fueling a global search for low‐energy‐consumption and high‐efficiency techniques to recycle air pollutants.…”

Environmental and energy issues are hot topicsi n the sustainable development of our planet. Air pollution, as av ital environmental issue, has puzzled us for decades, and ag reen and economical approacht oc ontrol air pollutantsi s urgently required. New energy-storage techniques have emerged as fascinating routes to reduce potentiale nvironmental problems. Therefore, the combination of air pollutants with energy-storage devices is an appealings olution for air pollution.H erein, the principles of recovering air pollutants for use in energy-storage materials are proposed, including their direct use as active materials, their conversion into active materials, and their use as dopants to modify the electrode. Typical air pollutants are selected to demonstrate their potentialuse in green energy storage. Futureprospects of the broad application of air pollutants in energy-related fields are also commentedo n.

The aim of the research – this article discusses findings from the experiments on the synthesis of catalysts in the protective layer and improvement of the technology for preparing catalysts using available raw materials. Evaluation of their efficiency in the processes of removing sulfur, oxygen and elemental mercury compounds from gas streams. For the synthesis of a catalyst of the protective layer, aluminum hydroxide of the pseudoboehmite modification was used, which had been obtained by processing of the wastes from the Shurtan gas-chemical complex manufacture – an alumina adsorbent after its use in the process of purifying a polyethylene solution. As a result of a series of comparative analyzes, it was found that the catalysts of the protective layer synthesized using pseudoboehmite obtained by processing of alumina waste completely satisfy the strength criterion, possess a set of physicochemical properties required for dehumidification of gas syrup from hydrogen sulfide and other harmful impurities, when the interaction of SO2 and H2 S in the ratio typical for the Mubarek gas processing plant. The most active and selective catalyst in the production of sulfur was exhibited by the Claus process catalyst.
