the effect of rare earth (re) elements, including ce and la, on the sorption properties of zr-co getters was investigated in this work. the phase evolution, microstructural characteristics of getter powders were studied by means of x-ray diffraction method, scanning electron microscopy (sem) and energy dispersive x-ray spectroscopy (eds). the nanostructured zr3co intermetallic compound has been...

This work presents the dynamic simulation of a novel sorption-enhanced water-gas shift reactor used for synthesis gas production from pure CO in an e-fuels process. Due to intended decentralized plant installation associated with fluctuating feed, process intensification and compact system is required. An optimized operating procedure was obtained by simulation-driven design maximize sorbent lo...

Pesticide adsorption by soil clays can be dramatically influenced by the exchangeable cations present. Among the common exchangeable base cations in soils (Ca2+, Mg2+, K+, and Na+), K+-saturated clays frequently demonstrate the strongest affinity for pesticides. In the presence of multiple exchangeable cations in the system, we hypothesize that the magnitude of pesticide sorption to soil minera...

The reactivity and removal kinetics of arsenite treated with single and mixed mineral systems of kaolinite, montmorillonite and goethite injected with iron sulfide under sulfidicanoxic conditions has been investigated. Using empirical models derived from Freundlich isotherm model, injection of sulfidic-anoxic solution of iron sulfide onto the mixed mineral systems enhanced proton coefficient of...

In the current work, we developed a facile synthesis of yolk/core-shell structured TS-1@mesosilica composites and studied their catalytic performances in the hydroxylation of phenol with H2O2 as the oxidant. The core-shell TS-1@mesosilica composites were prepared via a uniform coating process, while the yolk-shell TS-1@mesosilica composite was prepared using a resorcinol-formaldehyde resin (RF)...
