This book was released on 2012-12-06 with total page 306 pages. Available in PDF, EPUB and Kindle. Book excerpt: Masters Theses in the Pure and Applied Sciences was first conceived, published, and dis seminated by the Center for Information and Numerical Data Analysis and Synthesis (CINDAS) * at Purdue University in 1957, starting its coverage of theses with the academic year 1955. Beginning with Volume 13, the printing and dissemination phases of the ac tivity were transferred to University Microfilms/Xerox of Ann Arbor, Michigan, with the thought that such an arrangement would be more beneficial to the academic and general scientific and technical community. After five years of this joint undertaking we had concluded that it was in the interest of all concerned if the printing and distribution of the volume were handled by an international publishing house to assure improved service and broader dissemination. Hence, starting with Volume 18, Masters Theses in the Pure and Applied Sciences has been disseminated on a worldwide basis by Plenum Publishing Corporation of New York, and in the same year the coverage was broadened to include Canadian universities. All back issues can also be ordered from Plenum. We have reported in Volume 23 (thesis year 1978) a total of 10,148 theses titles from 27 Canadian and 220 United States universities. We are sure that this broader base for theses titles reported will greatly enhance the value of this important annual reference work. While Volume 23 reports these submitted in 1978, on occasion, certain universities do report theses submitted in previous years but not reported at the time.

Available in PDF, EPUB and Kindle. Book excerpt: The mixed gamma and chi crystalline phase alumina catalyst prepared by the solvothermal method of the mixed solution (toluene and 1-butanol) was investigated for the effect of calcination temperatures and MoO3 modification. The catalysts were characterized by X-ray diffraction (XRD), N2 physisorption, scanning electron microscopy (SEM), transmission electron microscopy (TEM) and NH3-tempearture programmed desorption (NH3-TPD). The catalytic activity was tested for ethylene production by dehydration reaction of ethanol in gas phase at atmospheric pressure and temperature between 200°C to 400°C. It was found that the calcination temperature and MoO3 loading have an effect on acidity of the catalysts. The increasing in calcination temperature resulted in decreased acidity while the MoO3 loading on the mixed phase alumina catalyst yielded increased acidity especially medium to strong acid. In this study, the catalytic activity of ethanol dehydration to ethylene apparently depends on the medium to strong acid. The mixed phase alumina catalyst calcined at 600°C (C50-600) gave the highest catalytic activity and the MoO3 modified catalysts promoted dehydrogenation reaction.

This book was released on 2016 with total page 332 pages. Available in PDF, EPUB and Kindle. Book excerpt: The mixture of 1:1 volume ratio of gamma and chi crystalline phase alumina support was prepared via the solvothermal technique using the mixed solution between toluene and 1-butanol. The support was brought to modify with phosphoric acid and noble metal agents. These catalysts were investigated on the effect of both phosphorus loading and types of noble metal on catalytic characteristic and catalytic activity. The catalytic performance was identified through ethanol dehydration reaction in gas phase process at 1 atm and temperature of 200oC to 400oC. The results were found that the phosphorus modification had an effect on catalytic acidity by decreasing the amount of medium to strong acid sites and raised quantity of weak acid sites. The higher amount of weak acid brought the catalysts to demonstrate the higher catalytic activity through the ethanol dehydration to diethyl ether. The mixed phase of alumina supports modified with 5 wt% of phosphorus exhibited the highest catalytic activity among other P-modified alumina catalysts giving the diethyl ether yield of 34.41%. In addition, the different types of noble metal modification were found to have a significant effect on catalytic performance. The 5P/Al2O3 catalyst deposited by palladium showed the highest catalytic activity through all of the studied catalysts reached 57.68% of diethyl ether yield. The highest average yield of diethyl ether of 42.50% was obtained from using Pd5P/Al2O3 catalyst in time on stream system for 10 h. Despite of high diethyl ether yield obtained, both 5P/Al2O3 and Pd5P/Al2O3 catalysts had the lower coke formation when compared to non-modified alumina supports.

Available in PDF, EPUB and Kindle. Book excerpt: In this study, gamma-Al[subscript 2]O[subscript 3] and amorphous AlPO[subscript 4] were synthesized and tested in methanol dehydration reaction. Both gamma-Al[subscript 2]O[subscript 3] and AlPO[subscript 4] catalysts showed increasing of activity when temperature direction during reaction test changed from step-up (150>200>250>300) to step-down (300>250>200>150). The effect of the presence of water product was studied by pretreatment of AlPO[subscript 4] catalyst with water various conditions. FT-IR and FT-Raman results indicated formation of P-OH group on the pretreated catalysts, which was one of intermediate for methanol dehydration. Amine titration also showed increasing of both strength and amount of acid sites on surface of the treated catalysts. The appropriate temperature on AlPO[subscript 4] catalyst was determined to be 200-250 degrees celsius for 10% mol of water in 5,300 h[superscript -1] GHSV for 15 minutes. On the other hand, the presence of water at 100 degrees celsius pretreatment became AlPO[subscript 4] poison which indicated by TGA and FT-Raman that physisorbed water could block the adsorption of methanol on catalyst active sites instead.

Available in PDF, EPUB and Kindle. Book excerpt: This volume looks at modern approaches to catalysis and reviews the extensive literature. Chapters highlight application of 2D materials in biomass conversion catalysis, plasmonic photocatalysis, catalytic demonstration of mesoporosity in the hierarchical zeolite and the effect of surface phase oxides on supported metals and catalysis. Looking to the future a chapter on ab initio machine learning for accelerating catalytic materials discovery is included. Appealing broadly to researchers in academia and industry, these illustrative chapters bridge the gap from academic studies in the laboratory to practical applications in industry not only for catalysis field but also for environmental protection. Other chapters with an industrial perspective include heterogeneous and homogeneous catalytic routes for vinyl acetate synthesis, catalysis for production of jet fuel from renewable sources by HDO/HDC and microwave-assisted catalysis for fuel conversion. Chemical reactions in ball mills is also explored. The book will be of great benefit to any researcher wanting a succinct reference on developments in this area now and looking to the future.
