Catalytic liquefaction of (Municipal sewage sludge) MSS over transition metal catalysts in ethanol-water co-solvent (EWCS) was investigated. The effect of operating parameters like temperature, holding time, and ethanol-water ratio was discussed. CuSO4 was selected as the most efficient catalyst. The highest biocrude yield (47.45%) and liquefaction conversion (97.74%) was both obtained at the s...

Flow liquefaction, which is characterized by sudden collapse following the unstable behavior of saturated loose sand, may lead to most catastrophic consequence all liquefaction-related phenomena. This note presents a systematic experimental investigation into flow liquefaction potential sand under various initial and cyclic shear conditions. The responses are compared with monotonic results an ...

due to its critical impact and significant destructive nature during and after seismic events, soil liquefaction and liquefactioninduced lateral ground spreading have been increasingly important topics in the geotechnical earthquake engineering field during the past four decades. the aim of this research is to develop an empirical model for the assessment of liquefaction-induced lateral ground ...

Purpose: To explore changes in the characteristics of water-in-oil-based high internal phase emulsion containing Moringa oleifera (Moringa HIPE) extract at various storage conditions and time intervals. Methods: Moringa leaves extract (3 %) was entrapped into HIPE. Color, liquefaction, conductivity, pH, and centrifugation were assessed by keeping the samples of Moringa HIPE at 8, 25, 40 and 40 ...

Abstract Understanding and quantifying the hazards related to earthquake-induced submarine liquefaction landslides are particularly significant offshore of tropical volcanic-carbonate islands, where carbonate production competes with volcanism create highly contrasted lithological successions. To improve detection liquefaction-prone layers, we analyzed physical properties mineralogy performed 7...

Deformation of quay walls is one of the main sources of damage to port facility while liquefaction of backfill and base soil of the wall are the main reasons for failures of quay walls. During earthquakes, the most susceptible materials for liquefaction in seashore regions are loose saturated sand. In this study, effects of enhancing the wall width and the soil improvement on the behavior of gr...

with high energy density, which makes it useful for storage and transportation over long distances from the gas fields to the consumers. LNG is recovered from natural gas in largescale liquefaction plants. Process automation is a key issue in LNG plants to ensure cost efficient plant operation and high product quality. Process analyzer deliver important data therefore. Siemens Sensors & Communi...

Soil liquefaction has been observed worldwide during recent major earthquakes with induced effects responsible for much of the damage, disruption of function, and considerable replacement expenses for structures. The phenomenon has not been documented in recent time with such damage in Italian context before the recent Emilia-Romagna Earthquake (May 2012). The main lateral spreading and vertica...

. The earthquakes of 1894, 1944, 1952 and 1977 occurred in the province San Juan central-wesern Argentina caused numerous processes soils sediment liquefaction, including those Ullum-Zonda valley. Historical records showed cracks, sand volcanoes, craters differential settlements, which significant damage to housing agro-industrial sector region. In this work, we carried out a study susceptibili...
