Low-graded coals to upgrade
Abstract: Coal can be defined as a chemically and physically heterogenous, “combustible”, sedimentary rock consisting of both organic and inorganic materials. Organically, coal consists primarily of carbon, hydrogen, and oxygen, with lesser amounts of sulphur and nitrogen. Inorganically, coal consists of a range of ash-forming compounds distributed throughout coal. Major types of analysis are proximate analysis, ultimate analysis and calorific value analysis. Heat value or calorific value determines energy content of …

Study of Dynamic Mechanical and Thermal Properties of Poly(Ether Ether Ketone) Carbon Nanotubes
Abstract: The effect of polyetherimide (PEI) as a compatibilizing agent on the morphology, thermal, electrical and dynamic-mechanical properties of poly(ether ether ketone) (PEEK)/single-walled carbon nanotube (SWCNT) nanocomposites, has been investigated for different CNT loadings. After a pre-processing step based on ball milling and premixing under mechanical treatments in ethanol, the samples were prepared by melt extrusion. A more homogeneous distribution of the CNTs throughout the matrix is found for composites containing …
