摘要： A method is provided for reducing the concentration of basic nitrogen compounds in hydrocarbonaceous feedstock fluids used in the refining industry by providing a solid particulate carbonaceous adsorbent/fuel material such as coal having active basic nitrogen complexing sites on the surface thereof and the coal with a hydrocarbonaceous feedstock containing basic nitrogen compounds to facilitate attraction of the basic nitrogen compounds to the complexing sites and the formation of complexes thereof on the surface of the coal. The adsorbent coal material and the complexes formed thereon are from the feedstock fluid to provide a hydrocarbonaceous fluid of reduced basic nitrogen compound concentration. The coal can then be used as fuel for boilers and the like.

摘要： An improved coal liquefaction process is provided whereby coal conversion is improved and yields of pentane soluble liquefaction products are increased. In this process, selected feed coal is pulverized and slurried with a process derived solvent, passed through a preheater and one or more dissolvers in the presence of hydrogen-rich gases at elevated temperatures and pressures, following which solids, including mineral ash and unconverted coal macerals, are separated from the condensed reactor effluent. The selected feed coals comprise washed coals having a substantial amount of mineral matter, preferably from about 25-75%, by weight, based upon run-of-mine coal, removed with at least 1.0% by weight of pyritic sulfur remaining and exhibiting vitrinite reflectance of less than about 0.70%.

摘要： A method is disclosed for producing large single crystals. According to the initial steps of this method, a plurality of single crystal wafers are crystallographically oriented to form a seed plate which is patterned. The patterned seed plate is selectively etched to expose the bare surface of the seed plate. The exposed, patterned bare surface of the seed plate is etched to form a plurality of nucleation structures. Each of the nucleation structures protrude outwardly from the underlying surface of the seed plate and provide ideal structures for the growth of large, single crystals. The resulting large, single crystals can be separated from the seed crystals by etching, physical or chemical means.

摘要： A method is disclosed for producing large single crystals. In one embodiment, a single crystal of electronic grade diamond is produced having a thickness of approximately 100-1000 microns and an area of substantially greater than 1 cm..sup.2. and having a high crystalline perfection which can be used in electronic, optical, mechanical and other applications. A single crystalline diamond layer is first deposited onto a master seed crystal and the resulting diamond layers can be separated from the seed crystal by physical, mechanical and chemical means. The original master seed can be restored by epitaxial growth for repetitive use as seed crystal in subsequent operations. Large master single crystal diamond seed can be generated by a combination of oriented smaller seed crystals by lateral epitaxial fusion. Since there is no limit to how many times seed combination step can be repeated, large diamond freestanding wafers comparable in size to silicon wafers can be manufactured.
