- Effect of Copper-based Catalyst Support on Reverse Water-Gas Shift Reaction (RWGS) Activity for CO2 Reduction
Damjan Lašič Jurković, Andrej Pohar, Venkata D. B. C. Dasireddy and Blaž Likozar
Version of Record online: 28 MAR 2017 | DOI: 10.1002/ceat.201600594
The reverse water gas shift reaction is a promising green process for syngas production. Numerous metal catalysts have been reported, but not much research has been done on the effects of the support. Five Cu catalysts with different supports were synthesized, characterized, and tested in a packed-bed reactor to determine the effect of the support on catalyst morphology, chemistry, and activity.
- Simple Apparatus for the Measurement of Total Pressure of Polymer-Solvent Mixtures
Jan Pavlíček, Grozdana Bogdanić and Ivan Wichterle

Determination of the vapor pressure of solutions with high polymer concentrations by conventional methods is challenging. A simple new setup to determine phase equilibria in systems containing one nonvolatile component was designed and applied to measure the pressure above three different water-poly(ethylene glycol) systems and these data were compared with published and predicted data.
- Detection of Microscale Mass-Transport Regimes in Supercritical Fluid Extraction
Arthur A. Salamatin
Version of Record online: 28 MAR 2017 | DOI: 10.1002/ceat.201600599
A generalized model of a particle-scale supercritical-fluid-extraction process is introduced. It is demonstrated that up-to-date experiments only allow identification of the initial extraction rates, which decrease or remain constant with time, depending on the assumed internal extraction regime. A methodology to detect the extraction regime in the particle is suggested.
- Adsorption of C1–C4 Alcohols, C4–C5 Isoolefins, and their Corresponding Ethers over Amberlyst™35
Rodrigo Soto, Nuray Oktar, Carles Fité, Eliana Ramírez, Roger Bringué and Javier Tejero
Version of Record online: 27 MAR 2017 | DOI: 10.1002/ceat.201600592
Ethers obtained from C1–C4 primary alcohols and C4–C5 isoolefins are potential environmentally benign gasoline additives. Liquid- and gas-phase adsorption equilibrium constants of the alcohols, isoolefins, and ethers on Amberlyst™35 were estimated and thereof adsorption enthalpies and entropies. Macro- and micropore diffusion coefficients of the adsorbing species were calculated from experimental data by means of the moment technique.
- Techno-Economic Analysis of Methane Pyrolysis in Molten Metals: Decarbonizing Natural Gas
Brett Parkinson, Joshua W. Matthews, Thomas B. McConnaughy, D. Chester Upham and Eric W. McFarland
Version of Record online: 27 MAR 2017 | DOI: 10.1002/ceat.201600414
Methane pyrolysis using a molten metal-based process to produce carbon and hydrogen is compared to steam methane reforming for the industrial production of hydrogen. Capital and operating cost models for pyrolysis and steam methane reforming were applied to generate cash-flow and production costs for several different pyrolysis systems making use of molten metals.
