Biodiesel synthesis via metal oxides and metal chlorides catalysis from marine alga Melanothamnus afaqhusainii

引用

Chinese Journal of Chemical Engineering 2016年第3期24卷 388-393页

作者： Abdul majeed Khan Noureen Fatima Research Laboratory of Bioenergy Department of ChemistryFederal Urdu University of ArtsSdence and TechnologyCulshan-e-lqbal CampusUniversity RoadKarachi-75300Pakistan

This research article demonstrates the most comprehensive comparative catalytic study of different metal oxides and metal chlorides towards the methanolysis of triglycerides of marine red macroalga Melanothamnus alhqhusainii. CaO was found to be the most reactive metal oxide that yielded 80% biodiesel while ZnCI2 was the most reactive metal chloride that produced 60% biodiesel by mechanical stirring for 6 h at 100-110 ℃. The overall reactivity order of the catalysts was found to be CaO 〉 MgO 〉 Pb02 〉 ZnC12 〉 TIC14 〉 PbO 〉 hgC12 〉 ZnO 〉 AIC13 〉 SnCI2 〉 TiO2 whereas, CaCI2, MgCI2, A1203, hgO, PbCI2, MnO2, MnC12, Fe203 and FeCI3 were found to be non-reactive for transesterification of triglycerides. In addition, a detailed study of the screening of mobile phases and spraying reagents was conducted which showed that petroleum ether ： chloroform ： toluene （7：2：1 ） is the best mobile phase, whereas iodine crystals/silica gel is the best visualizing agent for the thin layer chroma- tography （TLC） examination ofbiodiesel. Biodiesel production was confirmed by comparative TLC examination. It was further supported by the determination of fuel properties of biodiesel, which were found to be similar to the standard limits of American Society for Testing and Materials （ASTM）,

Vegetative propagation ofAesculus indica through stem cuttings treated with plant growth regulators

引用

Journal of Forestry Research 2009年第A2期20卷 171-173,I0004页

作者： Mumtaz majeed M.A. Khan A.h.Mughal Faculty of Forestry Sher-e-Kashmir University of Agricultural Science ＆ Technology Shalimar Srinagar- 191 121 J＆K lndia

Cuttage propagation of Aesculus indica was tested by treatments with different concentrations of indole-3-acetic acid （IAA） @ 2000, 4000 （ppm）, indolebutyric acid （IBA） @ 2000, 4000 （ppm） and naphthlcetic acid （NAA） @ 2000, 4000 （ppm） in dry formulation in the Forest Nursery, Faculty of Forestry, SKUAST-K, Shalimar. The cuttings treated with IBA @ 4000 ppm and IBA @ 2000 ppm had a sprouting rate of 75% and 50%, respectively, which was significantly higher than that of control and other treatments. The highest rooting rate （50%） was recorded in the cuttings with the application of IBA @ 4000 ppm. The cuttings treated with IBA @ 2000 ppm had 25% rooting rate. All other treatments along with control （talc powder） failed to induce rooting. It was concluded that IBA @ 4000 ppm was a better-applied concentration for vegetative propagation ofA. indica under Kashmir conditions.

Biodiesel production from green seaweed Ulva fasciata catalyzed by novel waste catalysts from Pakistan Steel Industry

Chinese Journal of Chemical Engineering 2016年第8期24卷 1080-1086页

作者： Abdul majeed Khan Noureen Fatima Muhammad Shoukat hussain Kousar Yasmeen Research Laboratory of Bioenergy (RLB) Department of Chemistry Federal Urdu University of Arts Science and Technology Gulshan-e-Iqbal Campus

This research article is based on the biodiesel synthesis from the marine green macroalga Ulva fasciata, collected from the coast of Karachi, Pakistan using new and the most potential waste catalysts from Pakistan Steel *** oil was extracted with n-hexane then it was analyzed by GC, TLC and by the examination of fuel *** metal analysis of catalysts was carried out by chemical tests and flame atomic absorption spectroscopy(FAAS). The thermal treatment of catalysts at 1500–1700 °C during various processes in steel manufacturing industry converted the metals to metal oxides. The presence of CaO, MgO and ZnO in these catalysts made them highly reactive for biodiesel synthesis. The basicity of waste industrial catalysts was calculated to know their basic strength. The transesterification of U. fasciata oil was performed by fast stirring using 9:1 molar ratio of methanol/oil in the presence of seven different waste industrial catalysts for 6 h at 80–100 °C. The solid catalysts were easily separated from product for re-use. In addition, the rate of reaction in the presence of these catalysts was found to be quite feasible. The waste brown dust from the steel converter gave the highest yield(88%) of biodiesel. The production of biodiesel was confirmed by TLC examination and fuel properties in comparison with the ASTM standards.

Journal of Signal and Information Processing 2011年第3期2卷 238-244页

作者： qais h. Alsafasfeh Aouda A. Arfoa 不详

In the recent years, researchers developed image encryption methods based on chaotic systems. This paper proposed new image encryption technique based on new chaotic system by adding two chaotic systems: the Lorenz chaotic system and the R?ssler chaotic system. The main advantage of this technique is stronger security, as is shown in the encryption tests.

Dormancy studies on Indian horse-chestnut (Aesculus indica Colebr.) under Kashmir conditions

引用

Forestry Studies in China 2010年第1期12卷 41-44页

作者： Mumtaz majeed M. A. KhAN Altamash BAShIR A. h. MUGhAL Faculty of Forestry Sher-e-Kashmir University of Agricultural Science & Technology of Kashmir

Studies were carried out in the Faculty of Forestry, Sher-e-Kashrnir University of Agricultural Sciences ＆ Technology of Kashmir, Shalimar of India during 2006 and 2007. The Indian horse-chestnut （Aesculus indica Colebr.）, locally known as ＂hanudun＂, is one of the more important broad-leaved tree species of the Kashmir valley. No deep dormancy was observed in mature seeds. however, the seeds remained dormant due to unfavorable environmental conditions prevailing after seed dispersal. Both treatments of cold stratification were significantly superior to the control conditions, i.e., no stratification which showed no germination during the test period of 30 d. The effects of the two treatments （cold stratification for 15 or 30 d） also differed significantly. Germination was found to increase with an increase in the time of cold stratification. Chilling treatments of seeds for 30 d showed maximum ger- mination of 80%, requiring the shortest time for germination, i.e., 20.51 d with a maximum evaluated germination value of 14.88. The other treatment with 15 d chilling showed lower germination of 60%, requiring a maximum number of germination days （27.31 d） with lower germination value of 3.26.

Circuits and Systems 2011年第2期2卷 101-105页

作者： qais h. Alsafasfeh Mohammad S. Al-Arni 不详

This paper presents a new three-dimensional continuous autonomous chaotic system with ten terms and three quadratic nonlinearities. The new system contains five variational parameters and exhibits Lorenz and Rossler like attractors in numerical simulations. The basic dynamical properties of the new system are analyzed by means of equilibrium points, eigenvalue structures. Some of the basic dynamic behavior of the system is explored further investigation in the Lyapunov Exponent. The new system examined in Matlab-Simulink and Orcad-PSpice. An electronic circuit realization of the proposed system is presented using analog electronic elements such as capacitors, resistors, operational amplifiers and multipliers.

Fault Classification and Localization in Power Systems Using Fault Signatures and Principal Components Analysis

引用

Energy and Power Engineering 2012年第6期4卷 506-522页

作者： qais h. Alsafasfeh Ikhlas Abdel-Qader Ahmad M. harb Department of Electrical and Computer Engineering Western Michigan University Kalamazoo USA Electrical Engineering Department Tafila Technical University Tafila Jordan Energy Engineering Department German Jordanian University Amman Jordan

A vital attribute of electrical power network is the continuity of service with a high level of reliability. This motivated many researchers to investigate power systems in an effort to improve reliability by focusing on fault detection, classification and localization. In this paper, a new protective relaying framework to detect, classify and localize faults in an electrical power transmission system is presented. This work will extract phase current values during ( )th of a cycle to generate unique signatures. By utilizing principal component analysis (PCA) methods, this system will identify and classify any fault instantaneously. Also, by using the curve fitting polynomial technique with our index pattern obtained from the unique fault signature, the location of the fault can be determined with a significant accuracy.
