    Abstract: Bio fuel is one of the emerging industries around the world due to arise of crisis in petroleum fuel. Fermentation is a cost effective and eco-friendly process in production of bio-fuel. One major problem in microbial ethanol fermentation is the low resistance of conventional microorganisms to the high ethanol concentrations, which ultimately lead ... Show More

    Abstract: The molecular structure of black citric acid polymer (PN) and their hydracids acids functions allowed without doubt their capacities to be potential raw materials for realizing a cationic exchanger. So, the objective of this publication was to study this capacity after activation with sodium hydroxide (NaOH) solution. Two black citric acid polymers... Show More

    Abstract: Niobium containing aluminophosphate molecular sieve (NbFAPSO-5) was hydrothermally synthesized with AlPO-5 type structure. Characterization of this catalyst was performed by X-ray diffraction to determine its structure, inductive coupled plasma-atomic emission spectrometry (ICP-AES) for its elemental composition and infrared spectrometry (IR) to ac...
