The potential for basin amplification of ground motion from significant seismic sources 100-200 km (62-124 mi.) from the Las Vegas Valley (such as the Death Valley Fault System) and Quaternary faults in the valley could provide sufficient energy to cause liquefaction. Key criteria of liquefiable soils coupled with a shallow groundwater table (less than 15 m (50 ft)) are met at several sites in ...

Liquefaction triggering assessments are often performed for individual locations, providing little information in regard to the expected spatial extent of liquefaction events. The present paper proposes a method to quantify the potential extent of liquefaction by accounting for spatial dependence of soil properties and potential future earthquake shaking. Random-field theory and geostatistics t...

The Sustainable Value methodology was used to compare and rank eight combinations of waste biomass types conversion technologies on a common assessment basis produce energy, energy vectors advanced biofuels. studied included agricultural agro-industrial residues, slurries effluents, pulp paper mill sludge, piggery effluents organic fractions municipal solid waste, biodiesel by (trans)esterifica...

• Electrochemical oxidation can reduce 99% of chemical oxygen demand HTL aqueous phase. Complex organics are predominantly degraded to organic acids and eventually CO 2. Hydrogen gas is produced simultaneously, potentially available for biocrude upgrading. The energy consumption using electro water cleaning significant. Post-hydrothermal liquefaction (HTL) phase treatment an emerging issue must...

One of the important problems in earthquake geotechnical engineering is liquefaction phenomenon that happens in loose saturated granular soils. This phenomenon can cause great damages to underground structures and buildings and lifelines. Liquefaction resistance of soils can be evaluated by experimental and field tests. The use of energy is a logical step in the evaluation of liquefaction asses...

Bagasse liquefaction (BL) in water, tetralin, and water/tetralin mixed solvents (WTMS) was investigated, and effects of tetralin content in WTMS, temperature, and alkaline pretreatment of bagasse on liquefaction efficiency were studied. At 300°C, bagasse conversion in WTMS with tetralin content higher than 50 wt% was 86-87 wt%, whereas bagasse conversion in water or tetralin was 67 wt% or 84 wt...

The mechanism of hydrothermal liquefaction of cypress was investigated by examining the effects of temperature and retention time on the characteristics of the solid residues remaining after liquefaction. The solid residues were divided into acid-soluble and acid-insoluble residues. Results showed the polymerization reactions also mainly occurred at low temperatures. The reactive fragments tran...

exhibited their new instruments in 1400 booths. Of the 900 papers presented at the conference, the following from the symposium on 'Process analysers' dealt with automated stream analysis for process control. Gibbon and Hackett [1] described the use of automated research-quality gas chromatographs to analyse the effluents from bench-scale coal gasification or liquefaction equipment. The high sp...

Microwave-assisted liquefaction has shown potential for rapid thermal processing of lignocellulosic biomass. The efficiency of microwave heating depends largely on the dielectric properties of the materials being heated. The objective of this study was to investigate the dynamic interactions between microwave energy and the reaction system during the liquefaction of a woody biomass sample. The ...
