(152ai) Adsorbent Characteristics for Effective Siloxane Removal from Gas Streams and Silicone Oils : A Study on Chemical and Structural Properties and Separation Selectivity

Siloxanes are a group of organic compounds commonly found in various industrial processes, including natural gas, biogas production, and silicone oil production. However, their presence in gas streams can cause significant problems, such as equipment damage, reduced efficiency, and environmental pollution. In addition, they are also present in silicone oils as unreacted agents. Effective siloxane removal is therefore crucial before gas utilization or disposal and silicone oil purification. Adsorption is one of the most effective methods for siloxane removal. It involves the use of various adsorbents to capture siloxanes from gas streams. This method utilizes very little energy on an industrial scale and is therefore viable for reducing operating costs and making industrial processes environmentally friendly.

This study aims to investigate the characteristics of various adsorbents and their effect on the adsorption of siloxanes. The primary objective of the research is to identify the optimal class of adsorbents, including zeolites, silica gels, activated carbons, and MOFs, for siloxane adsorption and determine the chemical and structural properties that make them suitable. In addition, the study aims to identify a suitable material for separating linear siloxanes from cyclic siloxanes by investigating selectivity, which will contribute to the purification of gas streams for reagent recycling. Finally, the research will examine the sorption kinetics of linear siloxanes versus cyclic siloxanes, which is crucial for understanding the adsorption behavior of these compounds.

The implications of this study are significant, as it can lead to the development of new methods for the effective separation of siloxanes, which is essential for the purification of gas streams. The findings of this study may also contribute to developing more efficient and cost-effective adsorbent materials for siloxane removal. Overall, the study will provide valuable insights into the adsorption of siloxanes.
