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...

Selective hydrogenolysis of the aromatic carbon-oxygen (C-O) bonds in aryl ethers is an unsolved synthetic problem important for the generation of fuels and chemical feedstocks from biomass and for the liquefaction of coal. Currently, the hydrogenolysis of aromatic C-O bonds requires heterogeneous catalysts that operate at high temperature and pressure and lead to a mixture of products from com...

during the last years the total cost of lng technology has decreased significantly due to improvements of the liquefaction process. however, many liquefaction plants that are still in operation use a three-cascade refrigeration system. in this paper, an advanced exergetic analysis is applied to better understand the operation of a three-cascade refrigeration system for liquefaction of natural g...

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 ...

Hydrogen adsorption on activated carbons (ACs) is a promising alternative to compression and liquefaction for storing hydrogen. Herein, we have studied hydrogen six commercial ACs (CACs) with surface areas ranging from 996 2216 m2 g–1 in temperature range of 77 273 K pressures up 15 MPa. Excess capacities 2.3 5.8 wt % were obtained at 4 We demonstrated that, contrary what normally done, capacit...

As the interest in hydrogen to help decarbonization of transport sector is growing fast, new methods for its storage a key point improve diffusion many contexts, investigating innovative methods. Ammonia promising solution, as content per volume unit higher than stored liquid form; furthermore, ammonia does not require cryogenic temperature nor high amounts energy liquefaction. In this study, t...

Description of the organim. The coccus Micrococcus 8odonensis, nov. sp., has the following characteristics: Spheres: 0.8-1.5 microns; occurring singly, in pairs, and in groups of four. Nonmotile, nonsporeforming, and gram positive. Gelatin stab: No liquefaction. Agar slant: Abundant, yellow, shiny, butyrous. Broth: Turbid with sediment. Indole not formed. Nitrates not reduced. Hydrogen sulfide ...

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...
