Abstract: A system for generating electricity and hydrogen is provided. The system includes a fuel cell unit, a liquid-gas separation unit, and a hydrogen separation unit. The fuel cell unit generates electricity and produces a fuel cell unit effluent stream containing hydrogen from a feed containing natural gas and water. The fuel cell unit includes a reformer, and the reformer includes a burner. The liquid-gas separation unit separates the fuel cell unit effluent stream into a liquid stream and a gas stream. The hydrogen separation unit separates the gas stream into a hydrogen stream and an off-gas stream. At least a portion of the off-gas stream is transferred to the burner of the reformer. The system can generate electricity and high purity hydrogen.

Abstract: The present disclosure relates to an apparatus for curing spinal stenosis which is an abnormal narrowing of the spinal canal between spinous processes, more particularly, to an apparatus of fixing spinous processes which can prevent the narrowing or widening of the spinal canal between spinous processes along the motion of the spine so as to enhance spinal stabilization. The apparatus of fixing the spinous processes includes a spacer having at least predetermined portion inserted between spinous processes of two neighboring vertebrae to support the spinous processes so as to prevent narrowing of the spinous processes which is generated by spinal bending; and a clip provided to cover an outer surface of the spinous processes of the two neighboring vertebrae to prevent widening of a distance between the spinous processes generated by the spinal bending.

Abstract: A method of manufacturing high-quality naphthenic base oils comprising a high aromatic content and a large amount of impurities with a boiling point higher than that of gasoline. High-quality naphthenic base oil may be manufactured from light cycle oil (LCO) and slurry oil (SLO), which are inexpensive, and have a high aromatic content, a large amount of impurities, and which are effluents of a fluidized catalytic cracking (FCC) unit. The method also relates to the pretreatment process of a feedstock, where the amounts of impurities (sulfur, nitrogen, polynuclear aromatic compounds and various metals components) in the feedstock are reduced.

Abstract: Disclosed herein is a method of producing feedstock of high-quality lube based oil by producing coker gas oil (CGO) from vacuum residue (VR) or a mixture (VR/AR) of atmospheric residue (AR) and vacuum residue (VR), performing a hydrotreating process and a hydrocracking process by mixing the coker gas oil (CGO) with vacuum gas oil (VGO) to form unconverted oil (UCO), and then recycling the unconverted oil.
