    摘要： This invention is a method to measure fluid flow properties of a porous medium, including, but not limited to, the fluid flow permeability. In a preferred embodiment, the measurements are made down hole in drill wells exploring for hydrocarbons or acquifers. The measurement involves two types of instruments. One instrument creates a pressure wave in the porous medium, which generates motion of the fluid in the pore space. The second instrument measures the fluid motion in the pore space using Nuclear Magnetic Resonance (NMR) methods. Any type of instrument that can generate a pressure gradient is suitable, including instruments that are remote from the NMR instrument.Magnetic field gradients can be used to localize the NMR signal to a specific region within the porous medium. The magnetic field gradient also provides the method by which the fluid motion is encoded on to the NMR signal. The permeability is calculated from the known pressure gradient present in the porous medium by virtue of the applied pressure gradient or pressure wave and the velocity of the fluid in the rock pore space as measured by NMR.

    摘要： This invention relates to a process of recycling condensate from a hydrocarbon or alcohol synthesis, wherein the condensate comprises water and contaminants such as lower molecular weight hydrocarbons, alcohols, and other oxygenates. A hot gaseous mixture comprising CH.sub.4 and steam contacts the condensate so as to strip the contaminants from the condensate. The stripped contaminants, CH.sub.4, and steam are separately recovered as a gaseous stream from the remaining purified water. The recovered CH.sub.4 -containing gaseous stream may be used in synthesis gas (CO/H.sub.2) generation processes with the generated synthesis gas then being used in a hydrocarbon synthesis process to produce heavy hydrocarbons.

    摘要： Hydrocarbon feeds are upgraded by contacting a feed, at elevated temperature and in the presence of hydrogen, with a catalyst comprising an amorphous sulfide of iron and a metal selected from the group consisting of Mo, W and mixture thereof. The catalysts are prepared by heating one or more catalyst precursor salts under oxygen-free conditions in the presence of sulfur at a temperature of at least about 250.degree. C. The precursor salts will contain a thiometallate anion of Mo, W or mixture thereof and a cation comprising iron as a promoter metal and, optionally, additional divalent promoter metals, wherein said promoter metal or metals are chelated by at least one neutral, nitrogen-containing polydentate ligand and wherein said additional promoter metal is selected from the group consisting of Ni, Co, Mn, Zn, Cu and mixture thereof.

    摘要： An ink jet apparatus employs phase change ink which may be heated for jetting and is characteristically solid at room temperature. The ink is delivered and then advanced to a melting location in the solid state. At the melting location, the ink is changed to liquid state, whereupon it is jetted. The ink in the solid state takes the form of pellets which are advanced by a carrier.
