Abstract
- The purpose of this work is to study the degree and structure of contamination of spent zeolites and their effect on adsorption-desorption characteristics in natural gas desulfurization processes, to determine the number and structure of zeolite transport pores and their role in the adsorption process, to develop an optimal method for the recovery of zeolite waste for their secondary use in desulfurization processes. In solving the above tasks, the methods of physical chemistry, quantitative and qualitative analysis of pollution products, the theory of redox reactions of the gorenje process, methods of calculating mass-heat exchange processes are used in the work. The study of the composition of spent zeolites showed that during long-term operation of zeolites in adsorption-desorption cycles at industrial natural gas desulfurization plants, they are contaminated with oxidation-reduction reaction products contained in raw gas, which leads to the deposition of these products on the zeolite surface and a sharp narrowing of transport pores.
