E-fuel production, which is achieved using atmospheric or biogenic CO2 and green H2, shows promise for reducing levels curtailing our reliance on fossil fuels. Notably, the hydrogenation of to CO via reverse water–gas shift (RWGS) reaction (CO2 + H2 ↔ H2O) plays a pivotal role in commercial e-fuel production. This approach preferred over direct conversion CO2, remains nascent stage. However, endothermic RWGS energy-intensive it requires high operating temperatures (∼600–800 °C). Therefore,...
A metal-free and all-organic redox flow battery is proposed investigated. It employs polythiophene microparticles dispersed in electrolyte solutions as the couple does not depend on limited metal resources. shows a high cell potential stable charge/discharge performance with energy efficiency of 60.9%.
Bimetallic alloy catalysts with finely controlled composition and atomic mixing of the two active metals are vital for maximizing their synergistic effect in enhancing catalytic performances. Herein, we report design synthetic strategy bimetallic Cu–Co well dispersed on Al2O3 from a CuCoAl-layered double hydroxide (LDH) boosting reverse water–gas shift (RWGS) performance by controlling textural properties particles. An optimized Cu9Co1/Al2O3 catalyst exhibits remarkably high CO2 to CO...
Epoxides are versatile chemical intermediates that used in the manufacture of diversified industrial products. For decades, thermochemical conversion has long been employed as primary synthetic route. However, it several drawbacks, such harsh and explosive operating conditions, well a significant greenhouse gas emissions problem. In this study, we propose an alternative electrocatalytic epoxidation reaction, using [CoIII(TAML)]- (TAML = tetraamido macrocyclic ligand) molecular catalyst....
A novel Fe<sub>5</sub>C<sub>2</sub>@C catalyst bearing small iron carbide particles ∼10 nm in diameter was prepared using a simple thermal treatment of oxalate dihydrate cubes, employed high-temperature Fischer–Tropsch synthesis.
Fischer–Tropsch synthesis (FTS) was carried out over precipitated iron-based catalysts activated by syngas (H2 + CO) with different amounts of CO2 (0%, 20%, 33%, and 50%). The activation using CO2-containing significantly suppressed the production undesired products, CH4 C2–C4 hydrocarbons, but facilitated valuable C5+ hydrocarbons. In particular, in case C19+ target products low-temperature FTS (⩽280 °C), both selectivity productivity showed a great increase an increased inlet content...
Highly activated K-doped Hägg-carbide/charcoal nanocatalyst at K/Fe = 0.075 showed the highest FTY value, best hydrocarbon yield, and a good gasoline selectivity for high-temperature Fischer–Tropsch reaction.
Mass transfer limitations on fixed-bed for Fischer–Tropsch synthesis were investigated by changing gas superficial velocity, catalyst pellet size, and amount. To study external mass limitation, velocity was changed from 8.47 × 10− 4 m s− 1 to 3.39 3 1. As a result, the of most suitable hydrocarbon chain growth resulting liquid formation. In case internal limitations, effects size amount (Wcat/F) discussed. The large showed higher C5+ selectivity lower α value compared small because more...
Finite element analysis.To compare the biomechanical stability imparted to C1 and C2 vertebrae by transarticular (TA), lateral mass (LM)-C2 pedicle (PS), C1LM-C2 pars, translaminar (TL) screw fixation techniques.Cadaveric studies of several atlantoaxial posterior techniques have been performed, showing significant heterogeneity in properties among studies.From computed tomography images, a nonlinear intact three-dimensional C1-2 finite model was developed validated. Four models were...
The catalytic hydrocracking of heavy wax derived from the pyrolysis waste plastics was conducted for valuable naphtha production on bifunctional catalyst. As result support screening to prepare catalyst, acidic Hβ chosen, which exhibited reasonable conversion (64%) and highest saturated unsaturated hydrocarbon content (98%) in fraction at 380 ̊C. Then, Pd impregnated as an active metal, ≥ 0.6% could dramatically improve cracking hydrogenation activities even 360 ̊C 47.9% >97.5% conversion....
