Study on Dehydration of Clay Minerals under N2 Reduced Pressure by Differential Thermal Analysis

Quantitative Thermal Analysis of Clay Minerals

Vold's mathematical analysis of the d.t.a, curve has been applied to Murray's data on the dehydration of clays. Owing to experimental uncertainties, values for the heats of dehydration are lower than those determined by other methods. The first ruder law is obeyed and the activation energies of dehydration are of the same order as those derived from isothermal data; rates of dehydration are, ho...

Thermal Analysis: A Complementary Method to Study the Shurijeh Clay Minerals

Clay minerals are considered the most important components of clastic reservoir rock evaluation studies. The Shurijeh gas reservoir Formation, represented by shaly sandstones of the Late Jurassic-Early Cretaceous age, is the main reservoir rock in the Eastern Kopet-Dagh sedimentary Basin, NE Iran. In this study, X-ray diffraction (XRD), X-ray fluorescence (XRF), scanning electron microscopic (S...

Differential Thermal Analysis and Dielectric Studies on Neopentanol under Pressure

Differential thermal analysis (DTA) and dielectric measurements have been performed on 2,2-dimethyl-l-propanol (neopentanol) up to 200 MPa. Neopentanol exhibits at least one orientationally disordered (ODIC) phase (solid I) that transforms at lower temperatures to a non-plastic phase (solid II). There is evidence of a further O D I C phase denoted as solid I'. The pressure dependence of the pha...

Reduction of nitroaromatic compounds by iron(ii) reduced clay minerals

Reduction of nitroaromatic compounds by iron(ii) reduced clay minerals." MS (Master of Science) thesis, undergraduate freshman I have had more than just support from this department as this department has become like family to me. I would like to give a special thanks to Dr. Michelle Scherer for giving the privilege to join her research group as an undergraduate student and for guiding me throu...
