Abstract: The present disclosure relates to a method of producing metallurgical coke from a combination of non-coking and non-metallic carbon-based microwave susceptor. The method is energy efficient, economical, and environmentally friendly. The present disclosure also relates to metallurgical coke having improved coke quality, such as improved coke strength after reaction.

Abstract: The present disclosure relates to organic compound(s) (i.e., compound of formula I or compound of formula IA) and/or a composition including the organic compound(s) useful for utilization of non-coking coal in a blend including coking coal without deterioration of properties of coking coal, wherein the organic compound(s) is capable of releasing hydrogen in the plastic region of coal. The present disclosure provides a simple, economical, non-toxic and efficient method for the preparation of the organic polymer, and a method for utilization of non-coking coal in blend including coking coal without deterioration of the properties of coke.

Abstract: The present disclosure relates to a method for producing metallurgical coke from non-coking coal. The method comprising, densifying, the non-coking coal to form pellets. The densified pellets will be placed in a microwave oven within plurality of bricks and are subjected for pyrolysis. For carrying our pyrolysis, the pellets are carried out by heating, the pellets in the microwave oven at a predetermined temperature under an inert atmosphere at atmospheric pressure, and then the pellets are cooled in the microwave oven under the inert atmosphere. This process coverts non-coking coal to the metallurgical coke in a quicker time, and without use of any susceptors.

Abstract: A method and apparatus for distingishing cancerous tumors and tissue from benign tumors and tissue or normal tissue using native fluorescence. The tissue to be examined is excited with a beam of monochromatic light at 300 nanometers (nm). The intensity of the native fluorescence emitted from tissue is measured at 340 and 440 nm. The ratio of the two intensities is then calculated and used as a basis for determining if the tissue is cancerous as opposed to benign or normal. The invention is based on the discovery that when tissue is excited with monochromatic light at 300 nm, the native fluorescence spectrum over the region from about 320 nm to 600 nm is the tissue that is cancerous and substantially different from the native fluorescence spectrum that would result if the tissue is either benign or normal. The technique is useful in invivo and in vitro testing of human as well as animal tissue.
