Hydrogen is reviewed as a possible new marine fuel, with emphasis on the challenges concerning sustainable production, board use and safety specifically hydrogen storage.
Extensive research has been carried on the molecular adsorption in high surface area materials such as carbonaceous and MOFs well atomic bonded hydrogen metals alloys. Clathrates stand among ones to be recently suggested for storage. Although, simulations predict lower capacity than expected by DOE norms, additional benefits of clathrates low production operational cost, fully reversible reaction, environmentally benign nature, risk flammability make them one most promising explored next...
Abstract Computational fluid dynamics (CFD) applies numerical methods to solve transport phenomena problems. These include, for example, problems related flow comprising the Navier–Stokes equations either compressible or incompressible fluids, together with turbulence models and continuity single multi‐component (reacting inert) systems. The design space is first segmented into discrete volume elements (meshing). finite method, subject of this article, discretizes in time produce a set...
The process intensification possibilities of a gas–solid vortex reactor have been studied for biomass fast pyrolysis using combination experiments (particle image velocimetry) and non-reactive reactive three-dimensional computational fluid dynamics simulations. High centrifugal forces (greater than 30g) are obtainable, which allows much higher slip velocities (>5 m s–1) more intense heat mass transfer between phases, could result in selectivities of, example, bio-oil production....
The process intensification abilities of gas–solid vortex units (GSVU) are very promising for processes. By working in a centrifugal force field, much higher slip velocities can be obtained compared to gravitational fluidized beds, resulting significant increase heat and mass transfer rates. In this work, local azimuthal radial particle an experimental GSVU simulated using the Euler–Euler framework OpenFOAM with image velocimetry measurements. With validated model, effect diameter, number...
Solid-state tuning of a mesostructured cellular foam (MCF) enhances hydrogen storage in clathrate hydrates. Grafting promoter-like molecules ( e.g. , tetrahydrofuran) at the internal surface MCF improved kinetics formation binary H 2 -THF hydrate.
This work contributes to a new generalized empirical correlation for predicting methane (CH4) hydrate equilibrium conditions in pure water. Unlike the conventional thermodynamic approach that involves complex reckoning, proposed equation is developed by regressing 215 experimental data points from literature and validating with 45 The temperature pressure range of 273.2–303.48 K 2.63–72.26 MPa, respectively. accuracy performance quantitatively evaluated using statistical error analysis. was...
Abstract Vortex units are commonly considered for various single and multiphase applications due to their process intensification capabilities. The transition from gas‐only flow gas–solid remains largely unexplored nonetheless. During this transition, primary phenomenon, jets, secondary phenomena, counterflow backflow, substantially reduced, before a rotating solids bed is established. This transitional regime referred as the vortex suppression regime. In present work, identified validated...
Abstract Mass spectrometry identifies the atomic mass of molecules and fragments in gas phase. The spectrometer ionizes that then pass through an electric or magnetic field towards a detector. modifies molecule's trajectory we infer from its direction velocity static stability path dynamic field. current is amplified spectrum generated location timing signal detector, translated into plot intensity as function mass‐over‐charge ratio.

Abstract Rather than sequestering carbon dioxide from the exhaust of chemical looping combustion reactors, together with water, it could be used as a source syngas. For first time, we split water to hydrogen and monoxide manganese ore. Specific CO production is 10–100 times higher Sr, Ce, Fe doped perovskites perovskites.
