Hydrogenation of carbon monoxide was investigated for cobalt carbide synthesized from Co3O4 by CO carburization in a fixed-bed reactor. The characterized BET surface area, X-ray diffraction, scanning electron microscopy, absorption near edge spectroscopy, and extended fine structure spectroscopy. catalysts were tested the slurry phase using continuously stirred tank reactor at P = 2.0 MPa, H2/CO 2:1 temperature range 493–523 K, with space velocities varying 1 to 3 Nl h–1 gcat–1. results...

A variety of palladated PCP pincer complexes are covalently tethered onto polymeric and silica supports via either amide or ether linkages evaluated in the Heck reaction iodobenzene n-butyl acrylate. The decomposition under conditions all studied is established through poisoning kinetic studies. Furthermore, initial steps pathway as well SCS Pd(II) proposed validated using situ NMR, mass spectroscopy, XAS computational methods. These findings together with our previous reports strongly...

Pt- and Pd-promoted CexZr1–xO2 mixed oxides were characterized investigated for passive NOx adsorber applications. X-ray diffraction analysis revealed a phase transition from tetragonal to cubic with increasing cerium content in CexZr1–xO2, while H2 CO chemisorption data all cases indicated average Pt Pd particle sizes of close 2 nm. H2-temperature programmed reduction (TPD) measurements shift the peak higher temperature Ce content, consistent corresponding increase degree oxidation....

Palladium supported on amorphous silica, mercapto-functionalized amine functionalized and zeolite Y has been studied as a catalyst in the Heck reaction of iodobenzene with butyl acrylate presence triethylamine base dimethylformamide solvent. Trapping soluble Pd poly(4-vinylpyridine), hot filtration tests during batchwise reaction, effluents from fixed bed continuous reactor support conclusion that leached is active phase for all catalysts tested. Two different paths leaching depend chemical...

The research on the simultaneous removal of NOx and VOCs by NH3-SCR catalysts has garnered widespread attention. However, stepwise both gases during co-removal process is often caused inconsistent activity windows. Furthermore, presence water vapor in flue gas adversely impacts catalyst greatly decreases its catalytic activity. In this study, low-temperature MnFeOx was selected to remove methanol, with a focus investigating influence H2O reactions. Results show that exhibited nearly 100%...

Abstract Background Towards the goal of integrating CO 2 capture using aqueous ammonia with its utilization for algae cultivation, Scenedesmus acutus (UTEX B72) was grown in 1100 L open raceway ponds and NH 3 supplied from gas cylinders. /NH mole ratios 7 10 were employed, mixture acting as a surrogate output scrubbing system ammonia. Results Compared to gaseous NaNO N‐source, displayed higher productivity at both ratios, ratio providing best growth. Depending on culturing conditions ratio,...

Well-defined Pt-nanoparticles with an average diameter of 1 nm supported on a series zeolite Y samples containing different monovalent (H+, Na+, K+, Rb+, and Cs+) divalent (Mg2+, Ca2+, Sr2+, Ba2+) cations have been used as model systems to investigate the effect promotor elements in oxidation CO excess oxygen. Time-resolved infrared spectroscopy measurements allowed us study temperature-programmed desorption from Pt nanoparticles monitor electronic changes local environment adsorbed CO. It...
