This study evaluates the performance of a molten carbonate fuel cell and micro gas turbine (MCFC/MGT) hybrid power system bi-fueled by city gas and biogas. The performance of the MCFC/MGT hybrid power system and MFCF/MGT hybrid power system response have been investigated experimentally and numerically. Results show that the MCFC, steam reformer, and catalytic combustor models are in agreement ...

The past decade has witnessed an explosion of techniques used to pattern polymers on the nano (1-100 nm) and submicrometre (100-1,000 nm) scale, driven by the extensive versatility of polymers for diverse applications, such as molecular electronics, data storage, optoelectronics, displays, sacrificial templates and all forms of sensors. Conceptually, most of the patterning techniques, including...

The structure of the rhombohedral (R-) AlPdCo phase was determined by single-crystal X-ray diffraction: space group R 3 (No. 148), a = 2.91019(8) nm and c = 1.31854(4) nm, V = 9.6709(5) nm3, atoms/cell = 660, F(000) = 12820, R = 0.0481 for the observed 3354 reflections measured by Mo K¡ radiation (­ = 0.071069 nm). R-AlPdCo has two types of pseudo-Mackay clusters (pMCs) around Co(12) at 18f and...

This study presents experimental analysis of biomass air-steam gasification for the enhancement H2 production in producer gas (PG). Wood pellets which are widely available Malaysia used this investigation. A pilot scale downdraft gasifier based on new three-layers annular reactor design was implemented to produce hydrogen enriched PG. The is initially heated using hot flue from LPG combustion s...

This study aimed to determine the effect of rice husk fluidization and variation in equivalence ratio bubbling fluidized bed gasifiers without sand materials. It also improve quality by reducing diameter husks. Therefore, bulk density increases, whereas voidage decreases, both which are main parameters for improving solid particles. Experiments were carried out at a velocity 0.82 m/s, varying e...

This work investigates the mechanical behavior of nanocrystalline aluminum, with special focus on deformation mechanisms, using molecular dynamics simulations an interatomic potential parameterized by authors. To this end, four samples grain sizes ranging from 8,2 to 14,2 nm were constructed, each a volume 15 x 20 nm3. As expected, data tensile tests at strain rate 1,0 109 s−1 showed inverse Ha...

Co-gasification of refuse derived fuel (RDF) and wood chips was experimented in the Nong Bua dual fluidised bed steam gasifier Thailand. The effect mass RDF pellets feed (R/F ratio) investigated on performance entire process conditions product gas properties. test results showed that addition small ratio up to 30% did not affect operation conditions. concentrations H2, CO, CO2, CH4 from a binar...

A downhole electric tubular resistive heater is proposed for the oil-shale in situ resorting. After flowing through a set of heating tubes, outlet temperature and flow rate injected gas can be conveniently adjusted to match requirement pyrolysis oil shale. The calculation demonstrates effects inner diameter, length tube, inlet on heat transfer performance heater. It was found that, compared wit...

In general, the biomass raw materials burned by power plants generally have characteristics of variable fuel types, high moisture content, and volatile content. this paper, a 130 t/h circulating fluidized bed (BCFB) model was established on MWorks platform with Modelica language. The influence type changes operation parameters, corresponding steady-state characteristics, dynamic BCFB were carri...

Advanced zero-gap alkaline electrolyzers can be operated at a significantly higher current density than traditional electrolyzers. We have investigated how their performance is influenced by diaphragm thickness, temperature and pressure. For this semi-empirical current-voltage model has been developed based on experimental data of 20 Nm3/h electrolyzer. The was extrapolated to thinner thickness...
