Abstract Kerolite/Mg-smectite mixed layer was used as inexpensive material to support metallic copper, with metal loadings (5–30 wt.%). These catalysts are active in gas-phase furfural hydrogenation, maintaining conversion values higher than 80 mol%, at 210 °C, after 5 h of time-on-stream, with high copper loading (15–30 wt.% Cu) catalysts, being furfuryl alcohol and 2-methylfuran the only detected products. The incorporation of Ce and Zn as promoters causes a decrease in the furfural conversion...

In this work the adsorption capacities of methylene blue on Mg-smectite and sepiolite and its derived material obtained after acid treatment and/or the addition of Fe at its surfaces are studied. Natural smectite with high Mg-content in its octahedral sheet (Mg-smectite) displays higher adsorption capacity than the sepiolite due to the ability of Mg-smectite to expand the basal spacing to accommodate methylene blue cations between adjacent layers and the inability of sepiolite to adsorb these ca...

Abstract The liquid phase of a peloid can be mineral-medicinal, marine or salt lake water. This study was designed to experimentally determine the interaction between two bentonites and one sepiolite, and seawater as well as dilutions thereof to verify the effect of salinity on instrumental texture measurements in clay-water mixtures prepared with these components. In all the clay-water mixtures tested, instrumental hardness and adhesiveness decreased with water content. For a given instrumental...

The effect of the microwave-assisted acid treatment (MAT) on the structure and texture of dioctahedral (montmorillonite) and trioctahedral (saponite) smectites, kerolitic clays and sepiolites were studied by scanning electron microscopy, nitrogen adsorption, X-ray fluorescence, X-ray diffraction and Fourier transform infrared spectroscopy. This study shows that in the smectite group of minerals the effectiveness of MAT is notably influenced by the chemical composition of the octahedral sheet, wh...

The Madrid Basin contains large and well developed deposits of Mg-clays of Miocene age. These were developed in an environment controlled by a lacustrine saline-alkaline environment with an arid or semi-arid climate, leading to large deposits of Mg-clays. This paper summarizes the study about the formation of Mg-clay minerals in the transition from mudflat lithofacies made-up of Mg-smectite to palustrine lithofacies where sepiolite is predominant. The samples collected in the field were characte...

Clay authigenesis mostly concerns: (a) the formation of clays by direct precipitation from solution, called “neoformation” and (b) development of clays by transformation of precursor minerals. Precipitation from solution implies that a new mineral structure crystallizes, so that a prior mineral structure is not inherited. Transformation of precursor detrital minerals, a process also termed “neoformation by addition”, can be conducted whether throughout precipitation on pre-existing natural surfa...

Abstract The present work is devoted to the study of the relationship among composition, properties and methane adsorption of selected Silurian black shales from the Badenas Formation, located near Checa town (Spain). These outcropping samples were collected in a formation, which is not considered as target for shale gas exploration. The clay minerals are predominant in the whole-rock samples and mostly composed of illite (both potassium and ammonium phases), rectorite and pyrophyllite with subo...

High pressure methane adsorption isotherms were measured on five shale core samples obtained during exploratory drilling from three boreholes located in the Colombia Middle Magdalena Valley Basin. The experiments were carried out at 50 °C and 75 °C and for pressures ranging up to 3.5 MPa under dry conditions through the use of a home- made manometric set-up. The effect of total organic carbon content (TOC), thermal maturity, clay content and specific surface area (SSA) on methane adsorption capa...

Abstract The study of CO 2 /CH 4 adsorption onto kerogen is relevant for shale gas production. Despite much expanded literature, reliable adsorption models still await for a complete description due to the complexity of kerogen. The objective of this study is to provide an original set of experimental data and to use the selectivity as an indicator to test the affinity of the sample for a component over another. The adsorption of pure CO 2 and the equimolar mixture CH 4 /CO 2 were explored on a ...

To prepare peloids for thermotherapy, the thermal behaviour of their component clay pastes needs to be known. This study was designed to experimentally determine the specific heat capacity and cooling kinetics of pastes prepared by adding different proportions of water to eight commercially available clays of different composition. According to exponential equations fitted to the cooling curves for the pastes, a new parameter designated the relaxation time is proposed. Using this parameter, the ...
