Application of Zeotype SAPO-34 Molecular Sieve as a Selective Adsorbent for Separation of Ethylene from Ethane
The process of ethylene production from ethane dehydrogenation is one of the interesting processes in the field of conversion the petroleum light gases to the valuable products. In this process, the outlet gaseous product is a combination of ethylene, ethane and hydrogen. Effective separation techniques are required for separation of ethylene from unreacted ethane. Here a new adsorbent approach...
متن کاملOptimizing the crystallinity and acidity of H-SAPO-34 by fluoride for synthesizing Cu/SAPO-34 NH3-SCR catalyst.
A series of H-SAPO-34 zeolites were synthesized by a hydrothermal method in fluoride media. The as-synthesized H-SAPO-34 zeolites were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), N2 physisorption, temperature-programmed desorption of NH3 (NH3-TPD) and nuclear magnetic resonance (NMR) measurements. The results showed that a certain concentration of F(-) anions p...
متن کاملRetrofit Design for Gas Sweetening Processes
Gas sweetening using amines is an important gas treatment process. Existing gas sweetening units may be revamped to achieve a variety of aims, for example to expand processing capacity, to reduce operating costs, to accommodate a different feed, to reduce emissions levels, etc. Current practice for retrofit design is to use engineering judgement and experience and simulation studies to identify...

متن کاملSynthesis of SAPO-34 catalysts via controlled crystal growth
Introduction SAPO-34 is a silicoaluminophosphate zeolite with 8-membered ring windows (~0.38nm) displaying chabazite structure. SAPO-34 is an efficient catalyst showing improved catalytic performance in reactions such as methanol conversion to olefins [1], oxidative dehydrogenation of propane [2], conversion of light alkenes [3]. Its catalytic properties are mainly attributed to its mild acidit...
