Aluminophosphate-5 (AlPO4-5) nano-pore zeolite was synthesized. The effect of alteration in precursor gel preparation on the morphology of zeolite was studied. The effect of variety of synthesis conditions on the purity, crystal and pore size, and crystallinity of AlPO4-5 zeolite been studied. A hydrothermal synthesis has been used to produce nano-pore Aluminophosphate-5 c...

One way to take advantage from out-of-specification biodiesel and waste tank bottom drainage is co-process them in a fluidized catalytic cracking (FCC) unit. The present work deals with the of oleic acid methyl ester (OAME) as model, under conditions close that FCC process over ZSM-5 Y zeolites, either protonated or sodium forms, towards deoxygenated compounds. Catalytic fast OAME pre-adsorbed ...

Calcareous soil suffers from deficiency in available of potassium due to its high contain CaCO3. So, it is important increase the availability potassium. Potassium release rate constant an indicator for ability supply A field experiments sulaimani governorate was conducted evaluate effect amendment with natural zeolite at (0 and 2 t ha-1), three levels Nano fertilizer (0, 5 10 kg conventional K...

A computational study of the electronic structure and stability of complexes formed between Zeolite Y and boric acid was carried out at the HF and B3LYP levels using 6-31G* basis set. Five structures located as local minimum in PES of complex (structures d, e, f, g, and h). The most stable structure is formed due to hydrogen bonding between two hydroxyl of boric acid and both oxygen of ...

The development of accurate force fields is vital for predicting adsorption in porous materials. Previously, we introduced a first principles-based transferable force field for CO2 adsorption in siliceous zeolites (Fang et al., J. Phys. Chem. C, 2012, 116, 10692). In this study, we extend our approach to CO2 adsorption in cationic zeolites which possess more complex structures. Na-exchanged zeo...
