The production of dry-grind corn ethanol results in the generation of intermediate products, thin and whole stillage, which require energy-intensive downstream processing for conversion into commercial animal feed products. Hydrothermal carbonization of thin and whole stillage coupled with anaerobic digestion was investigated as alternative processing methods that could benefit the industry. By...

[1] Atmospheric organic aerosol concentrations depend in part on the gas-particle partitioning of primary organic aerosol (POA) emissions. Consequently, heating and dilution were used to investigate the volatility of biomass-burning smoke particles from combustion of common North American trees/shrubs/grasses during the third Fire Lab at Missoula Experiment. Fifty to eighty percent of the mass ...

BACKGROUND Replacing the energy-intensive evaporation of stillage by anaerobic digestion is one way of decreasing the energy demand of the lignocellulosic biomass to the ethanol process. The biogas can be upgraded and sold as transportation fuel, injected directly into the gas grid or be incinerated on-site for combined heat and power generation. A techno-economic evaluation of the spruce-to-et...

The vaporization characteristics of a single fuel droplet subjected to rapid gas-phase compression (i.e., wet compression) are computationally investigated using two spherically-symmetric models: quasisteady (QS) and fully transient (TS). Features of the wet compression process under rapid compression machine (RCM) conditions are discussed with these compared to simulations where the far-field ...

Zirconium oxide (ZrO2) has generated wide interest because of its potential in applications such as solid oxide fuel cells, catalysts and optical devices. In these applications, it is important to control the grain size of the material and increase the surface area by introducing porosity with tailored pore size. This paper presents a synthesis route for the preparation of mesoporous zirconia u...

Fiber-optic sensors provide remote access, are readily embedded within structures, and can operate in harsh environments. Nevertheless, fiber-optic sensing of liquids has been largely restricted to measurements of refractive index and absorption spectroscopy. The temporal dynamics of fluid evaporation have potential applications in monitoring the quality of water, identification of fuel dilutio...

This study is a preliminary research to specify fire scenarios in storage tanks and evaluate the size based on type of fuel diameter tank by applying liquid evaporation model FDS . version 6.7.6 was used analysis, computational domains were established pool with same proportion. The results obtained from indicated that heat feedback surface relatively well matched previous empirical correlation...

weather and climate have considerable influence on the concentration of air pollutants such as particles and gases. the range and concentration of these particles and gases are very dependent on prevailing weather conditions and air currents. this research concentrates on health effects of benzene, one of the air pollutants of tehran, as a major city. the concentration of benzene emission to ai...

establishing satisfactory estimation methods of lake evaporation has been crucial vital for research and management of water resources and ecosystems. determining the accurate method to estimate evaporation from reservoirs in the investigation and management of water resources is very important. hence, in this study eight empirical methods such as; makkink, debruin-kejiman, penman, priestley-ta...

Abstract LiCoO 2 , a widely used electrode material for Li-ion batteries, was found to be suitable as cathode proton-conducting solid oxide fuel cells (H-SOFCs). Although the evaporation of Li in detrimental battery performance, Li-evaporation beneficial H-SOFCs. The partial preparation procedure led in-situ formation +Co 3 O 4 composite. Compared cell using pure phase that only generated moder...
