In this work, steam methane reforming is carried out on 200CPSI mullite monoliths, loaded with Ni or Pd catalysts encapsulated in a 200mm long 316 grade stainless-steel reactor placed in front of a 70 cm diameter parabolic mirror with a 30x30mm focal area. The reactor-dish assembly was mounted on a dual axis solar tracker. Measured reaction temperatures varied significantly due to weather conditions, enabling the characterization of the relationship between conversion, temperature and extent of reaction. Peak H2 yields of ~99% were demonstrated on both materials, with the average in the range of 50-70%. The discontinuities in the water supply in the feed prevented sustainable >90% yields. Hourly production rates were between 0.05-0.10 moles of H2. Differences between the two catalysts and the advantages of running multiple micro reactors will be discussed along with the possibilities of improving the average yield levels by a more efficiently designed water feeding strategy.

SOLAR IRRADIATION ESTIMATION ON A SOLAR POWERED UAV OVER A MISSION COURSE
Ozcan, Guclu; Alemdaroglu, Nafiz (2015-06-12)
This paper is about solar irradiation estimation on a solar powered UAV over its mission course [1]. Solar irradiation estimation and maximizing the solar energy collection are critical for solar powered UAVs and their performance. In this paper main focus is on solar irradiation calculations and comparison of two possible flight paths for solar energy collection during a transport or inspection mission.
Combustion Behavior and Kinetics of Turkish Lignite Blended with Biomass/Magnesite Dust
Farrokhi, Farshid Yousefzad; Kazanç Özerinç, Feyza (American Society of Civil Engineers (ASCE), 2018-12-01)
The effect of blending on the combustion behavior of a Turkish lignite blended with biomass or magnesite dust using a thermogravimetric analyzer (TGA) coupled with a Fourier transform infrared spectrometer (FTIR) under air atmosphere has been investigated. The lignite used in this study is Tuncbilek lignite (TL), which is blended with two biomasses, olive residue (OR) and almond shell (AS), and the inorganic industrial waste, magnesite dust (MD). The blends are composed of various weight fractions of fuels,...
Catalytic partial oxidation of propylene on metal surfaces by means of quantum chemical methods
Kızılkaya, Ali Can; Önal, Işık; Department of Chemical Engineering (2010)
Direct, gas phase propylene epoxidation reactions are carried out on model slabs representing Ru-Cu(111) bimetallic and Cu(111) metallic catalyst surfaces with periodic Density Functional Theory (DFT) calculations. Ru-Cu(111) surface is modelled as a Cu(111) monolayer totally covering the surface of Ru(0001) surface underneath. The catalytic activity is evaluated following the generally accepted oxametallacycle mechanism. It is shown that the Ru-Cu(111) surface has a lower energy barrier (0.48 eV) for the s...
Heat transfer enhancement by silver nanowire suspensions in microchannel heat sinks
SIMSEK, Eylul; Coskun, Sahin; OKUTUCU-OZYURT, Tuba; Ünalan, Hüsnü Emrah (2018-01-01)
Convection heat transfer and pressure drop characteristics of water based silver nanowire suspensions flowing through CMOS compatible monolithic microchannel heat sinks are investigated experimentally. Three different rectangular channels of 200 mu m x 50 mu m, 100 mu m x 50 mu m and 70 mu m x 50 mu m cross sectional area are used during the experiments. The stability of the silver nanofluids is established by the added polyvinylpyrrolidone (PVP) as the surfactant. To investigate the potential heat transfer...
Characterization of gas turbine burner instabilities by wavelet analysis of infrared images
Allouis, Christophe Gerard; Amoresano, A.; Langella, G.; Niola, V.; Quaremba, G. (2016-05-01)
In this paper, an optical approach is tested to spatially characterize combustion fluctuations in a single burner atmospheric gas turbine test rig. The target of present investigation was to test the optical technique during combustion tests campaign, in order to couple it to an acoustic one in a future activity to be developed on the same experimental setup. The analysis based on fast infrared imaging of flames, coupled with photomultiplier and microphones measurements, has been elaborated on a 3 MW gas tu...
