Hydrothermal Reactivity of Mixed-layer Kaolinite/smectite: Experimental Transformation of High-charge to Low-charge Smectite
-A mixed-layer kaolinite/smectite (K/S) containing trace amounts of quartz, discrete kaolinite, goethite-hematite, and calcite was hydrothermally reacted with deionized water at 150", 200", and 250"C for 1 to 12 months. The starting K/S contained 50% smectite consisting of 15~ low-charge and 350 high-charge layers. The X-ray powder diffraction and chemical analyses of the reacted products indic...
متن کاملHydrothermal Origin of Smectite in Volcanic Ash
Abstraet--Smectite and fine-grained quartz were separated from 6 volcanic ash samples collected in Japan from Shinmoe-dake Volcano, southern Kyushu, and Mt. Usu Volcano, southern Hokkaido. Oxygen isotope ratios of smectite in the volcanic ash range from +6,9 to + 12.9 per mill (%o), which are comparable to the values of smectite (~lsO = +6.5 and +9.4%0) from currently active geothermal fields. ...
متن کاملConversion of Municipal Solid Wastes into Biochar through Hydrothermal Carbonization
In this study, the hydrothermal treatment of municipal solid wastes (MSWs) for the production of biochar as a renewable solid fuel was investigated. The properties of surrogate MSWs and mixtures of newspaper and vegetables were greatly improved by hydrothermal treatment and were similar to those of coal-like fuel substances. Hydrothermal treatment increased the calorific value, the fixed carbon...
متن کاملSynthesis of nano-hydroxyapatite under a sonochemical/hydrothermal condition.
In this study, hydroxyapatite (denoted as HAp) nanostructure with uniform morphologies, controllable size, nano-dispersion and narrow size distribution in diameter has been synthesized successfully by low-temperature hydrothermal process, and the as-synthesized powders were characterized by XRD, scanning electron microscopy, high-resolution transmission microscopy, FT-IR, Zetasizer and inductiv...
