Abstract
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.
