Adsorptive separation of C2H6 and H 2S from CH4.

摘要

The natural gas industry recognises that the need for removal of CH4 from C2H6 feedstock C2H4 production and utilization. CH4 being a contaminant in the production of C2H4 and furthermore in the production of polymers from C2H4. Dethanizers in gas processing plants are energy intensive and decreasing the energy from harvesting ethane from natural gas will improve the economics of C2H6 utilization. Na, Ba, and Ba/H exchanged forms of ETS-10 are investigated. Microwave radiation regeneration via desorption with H2O is also investigated.;Precious metal catalysts that utilize natural gas must be protected from decreased efficiency and fouling due to H2S contamination. This work proposes a guard bed method utilizing Zeoilite 13X, Cu-13X, Zn-13X, Pd-13X, and HiAl13X to remove the H2S from a natural gas. These materials will be studied at room temperature to avoid the cost of heating a reactive bed such as the ones utilized in ZnO reactive operations.
