Dimethyl ether is an excellent clean burning transportation fuel alternate for compression ignition engines and also an excellent fuel for household use. In the present study, catalytic performances of different alumina based catalysts, namely alumina impregnated SBA-15, a mesoporous aluminosilicate, which was synthesized following a one-pot hydrothermal procedure, and a commercial alumina catalyst, were tested in dehydration of methanol to produce dimethyl ether. Alumina impregnated SBA-15 had high Bronsted acidity, which facilitated the formation of dimethyl ether. This catalyst showed methanol conversion values close to equilibrium and about 100% dimethyl ether selectivity, at temperatures over 300 degrees C. The commercial alumina catalyst Al-T also showed very good performance in DME synthesis from methanol, even at temperatures lower than 300 degrees C.

Methanol dehydration reaction to produce clean diesel alternative dimethylether over mesoporous aluminosilicate-based catalysts VARIŞLI, DİLEK; Tokay, Kenan Cem; Ciftci, Ayseguel; DOĞU, TİMUR; Doğu, Timur (2009-06-01) Due to its good burning characteristics and high cetane number, dimethylether (DME) is considered as a highly attractive and clean alternative to diesel fuel. This ether can be produced by methanol dehydration reaction over solid acid catalysts. In the present study, activities of mesoporous aluminosilicate catalysts prepared by the hydrothermal synthesis route and containing Al/Si atomic ratios ranging between 0.03 and 0.18 were tested in methanol dehydration. The optimum Al/Si ratio was 0.09 for DME synth...
Sooting behavior of ethanol droplet combustion at elevated pressures under microgravity conditions URBAN, BRADLEY D; KROENLEİN, KENNETH; KAZAKOV, ANDREİ; DRYER, FREDERİCK L; Yozgatlıgil, Ahmet; CHOI, MUN YOUNG; MANZELLO, SAMUEL L; LEE, KYEONG OOK; DOBASHİ, RİTSU (Springer Science and Business Media LLC, 2004-01-01) Liquid ethanol is widely used in practical fuels as a means to extend petroleum-derived resources or as a fuel additive to reduce emissions of carbon monoxide from spark ignition engines. Recent research has also suggested that ethanol and other oxygenates could be added to diesel fuel to reduce particulate emissions. In this cursory study, the combustion of small ethanol droplets in microgravity environments was observed to investigate diffusion flame characteristics at higher ambient pressures and at vari...
Numerical study of combustion and emission characteristics of dual-fuel engines using 3D-CFD models coupled with chemical kinetics Maghbouli, Amin; Saray, Rahim Khoshbakhti; Shafee, Sina; Ghafouri, Jafar (2013-04-01) Dual-fuel combustion provides a relatively easy and inexpensive alternative to conventional diesel engine combustion by drastically reducing fuel consumption with comparable performance characteristics. Accurate simulation of the dual-fuel combustion requires utilization of a detailed chemistry combined with a flow simulation code. In the present study, the combustion process within the diesel and diesel/gas dual-fuel engine is investigated by use of a coupled 3D-CFD/chemical kinetics framework. In this stu...
Dimethyl Ether Synthesis over Novel Silicotungstic Acid Incorporated Nanostructured Catalysts Ciftci, Aysegul; VARIŞLI, DİLEK; Doğu, Timur (2010-01-01) Dimethyl ether (DME), which is an excellent green diesel-fuel alternate with excellent clean burning properties, is synthesized by dehydration of methanol over novel solid acid catalysts, which are synthesized following a direct hydrothermal route and using silicotungstic acid (STA) as the active compound. These mesoporous silicate structured catalysts have surface area values of 108-393 m(2)/g, depending upon their W/Si ratio. These catalysts showed very high methanol dehydration activity and also very hig...
Optimization of CO2/CO Ratio and Temperature for Dimethyl Ether Synthesis from Syngas over a New Bifunctional Catalyst Pair Containing Heteropolyacid Impregnated Mesoporous Alumina Bayat, Aysegul; Doğu, Timur (2016-11-09) Dimethyl ether (DME) is a promising nonpetroleum diesel fuel alternate. Synthesis of DME was achieved directly from synthesis gas having different compositions, over bifunctional hybrid catalysts. Silicotungstic acid impregnated mesoporous alumina (STA@MA) was shown to be an excellent catalyst to be used as the dehydration component of the hybrid catalyst combination. Results proved that feed composition, as well as reaction temperature had important influence on product distributions, as well as on DME yie...
