Non-processed kaolin (flint kaolin) from a mine located in the Capim area (Amazon region, northern Brazil), usually considered as waste, was selected source of silicon and aluminum synthesis SAPO-34. This is molecular sieve cationic exchanger chosen for tests focusing on removal methylene blue aqueous solutions, which dye widely used by textile industries Brazil. The results revealed that SAPO-...

In this paper, the performances of potential zeolite membranes were estimated by the Maxwell-Stefan model and then they were placed in Robeson plot of propylene/propane separation. Additionally, the effects of feed pressure and the mole fraction of propylene in the feed on both the propylene permeabilities and membrane permselectivities were investigated. The results showed that zeolite membran...

The search for adsorbents flue gas desulfurization processes is a current interest. For the first time, comparative experimental study of SO2 adsorption by porous materials including prototypical metal–organic frameworks NH2-MIL-101(Cr), Basolite F300 (Fe-1,3,5-BTC), HKUST-1 (Cu-BTC), zeolitic imidazolate (ZIF)-8, ZIF-67, alumosilicate Zeolite Y, silicoaluminumphosphate (SAPO)-34, Silica gel 60...

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...
