Bio-oils derived from the pyrolysis of lignin-based biomass often contain a variety oxygenated compounds, which can compromise their usefulness as fuel. To improve quality bio-oil, catalytic hydrodeoxygenation (HDO) is crucial step that removes oxygen oil in form water. In this study, we showed MFI nanosheets are excellent supports for Ru-catalysts. We synthesized highly crystalline using simpl...

Little is known about the performance of ettringite-based binders in hydrothermal conditions. This investigation aims to gain insights into phase evolution and corresponding mechanical an binder considering crystallization pressure caused by late-reaction products. Additionally, role fiber reinforcement on strength retention was investigated. When aged at elevated temperature under water-satura...

Abstract In-situ zeolites NaY and Na[B]Y were synthesized on microspherical matrices of kaolin to obtain FCC catalysts. An alkaline pretreatment the matrix was investigated in order evaluate its effect properties crystallization in-situ synthetized zeolites. Catalysts characterized by SEM, TEM, Ar adsorption, XRD NH 3 -TPD. It observed an increase surface area mesoporosity treated catalysts eit...

nanocomposites based on polyamide 6 (pa6) and poly(ethylene-co-1-butene)-graft-maleic anhydride (eb-g-mah) blends have been prepared via melt mixing. the effect of blend ratio and organoclay concentration onthe crystallization and melting behavior of specimens were studied. three types of commercial organo-modifiedclay (cloisite 30b, cloisite 15a and cloisite 20a) were employed to assess the im...

In this study, the hydrothermal treatment of municipal solid wastes (MSWs) for the production of biochar as a renewable solid fuel was investigated. The properties of surrogate MSWs and mixtures of newspaper and vegetables were greatly improved by hydrothermal treatment and were similar to those of coal-like fuel substances. Hydrothermal treatment increased the calorific value, the fixed carbon...

We report the genome sequence of Thermococcus superprofundus strain CDGS(T), a new piezophilic and hyperthermophilic member of the order Thermococcales isolated from the world's deepest hydrothermal vents, at the Mid-Cayman Rise. The genome is consistent with a heterotrophic, anaerobic, and piezophilic lifestyle.

Titanite is an important mineral in petrochronology studies. Understanding chemical signatures of titanite from different environments can provide significant data unraveling the complex histories recorded their textures and compositions. Using a database over 8500 analyses both literature (3829) our own (4900), we found that ratio Fe/Al useful for separating igneous (Fe/Al typically close to 1...

The thermal structure of mid-ocean ridge axes is a critical control on the mechanical properties young lithosphere and modulates faulting styles that shape Earth's seafloor. Models balance steady input magmatic heat with vigorous hydrothermal output are generally successful at explaining state magmatically robust ridges. However, magma supply ultraslow spreading ridges often subdued highly epis...

A knowledge of the stability of iron complexes in hydrothermal solutions is important for quantitative interpretation of the chemical behaviour of iron in hydrothermal systems. It is generally accepted that iron is predominantly transported as Fe(II) species in reduced acid fluids whereas Fe(III) hydroxy complexes become also important in reduced alkaline solutions. Previous studies on iron tra...
