Item Prediction of Wax Appearance Temperature Using Artificial Intelligent Techniques(Springer, 2020) Benamara, Chahrazed; Gharb, Kheira; Nait Amar, Menad; Hamada, BoudjemaThe paraffin particles can promote and be involved in the formation of deposits which can lead to plugging of oil production facilities. In this work, an experimental prediction of wax appearance temperature (WAT) has been performed on 59 Algerian crude oil samples using a pour point tester. In addition, a modeling investigation was done to create reliable WAT paradigms. To do so, gene expression programming and multilayers perceptron optimized with Levenberg–Marquardt algorithm (MLP-LMA) and Bayesian regularization algorithm were implemented. To generate these models, some parameters, namely density, viscosity, pour point, freezing point and wax content in crude oils, have been used as input parameters. The results reveal that the developed models provide satisfactory results. Furthermore, the comparison between these models in terms of accuracy indicates that MLP-LMA has the best performances with an overall average absolute relative error of 0.23% and a correlation coefficient of 0.9475.Item Behavior of transition metals in the structuring of nanostructures(Taylor & Francis, 2019) Khalili, Benyoucef; Boucenna, Ali; Hamada, BoudjemaItem Catalytic preparation, characterization and performance isomerization of M-Xylene by modified montmorillonite prepared by microwave(2013) Chemat- Djennia, Zoubida; Yelda Bakoz, Pemanos; Hamada, BoudjemaItem Synthesis of retinoid analogues of juvenile hormones(Wiley, 2017) Doumandji, Lotfi; Matondo, Hubert; Estaran, Sébastien; Hamada, Boudjema; Lagneau, Christophe; Devillers, James; Yébakima, André; Doucet‐Panaye, Annick; Doucet, Jean‐Pierre; Lattes, ArmandItem Hydrolytic decontamination of methyl parathion in the presence of 2-aminoethanol : kinetics study(Pesticide Science Society of Japan, 2018) Doumandji, Lotfi; Moussiden, Anissa; Ihdene, Zaher; Hamada, BoudjemaItem Microwave-assisted extractive catalytic-oxidative desulfurization of diesel fuel via a VO(acac)2/ionic liquid system with H2O2 and H2SO4 as oxidizing agents(Taylor & Francis, 2017) Mesdour, Souad; Lekbir, Choukri; Doumandji, Lotfi; Hamada, BoudjemaItem Extractive purification of hydro-treated gas oil with N-methylpyrrolidone(Serbian Chemical Society, 2017) Bedda, Kahina; Hamada, Boudjema; Kuzichkin, Nikolay V.; Semikin, Kirill V.The purification of hydro-treated gas oil by liquid–liquid extraction with N-methylpyrrolidone as solvent was studied. The results showed that this method, under appropriate experimental conditions, reduced the sulphur content of the gas oil from 174 to 28 ppm, the nitrogen content was decreased from 58 to 15 ppm, the aromatics content was diminished from 27.1 to 13.8 % and the polycyclic aromatic hydrocarbons were totally extracted. The obtained refined gas oil could be used to produce clean diesel fuel, thus protecting the environmentItem On the temperature programmed reduction characterization of the CoMo/γ-Al2O3+(x)CuY catalysts : the dynamic interconversion behavior(2012) Boukoberine, Yamina; Hamada, BoudjemaItem Détection des organophosphorés par réaction enzymatique : étude cinétique = Detection of organophosphates using enzymatic reactions : a kinetic study(Elsevier, 2011) Ihdene, Zaher; Dokhan, Sohère; Krutikov, Victor; Hamada, BoudjemaItem Optimization of hydrolysis degradation of neurotoxic pesticide methylparathion using a response surface methodology ( RSM )(IOSR Journal of Applied Chemistry (IOSR - JAC), 2015) Doumandji, Lotfi; Moussiden, Anissa; Benmabrouka, Hafsa; Boufades, Djamila; Zaher, Ihdene; PemanosYelda, Bakos; Hamada, Boudjema
