    • Heavy crude oil containing at least 1% by weight water is hydrotreated and upgraded while being produced downhole in a production well. During production the heavy crude oil containing water is subjected to sonic energy at a low frequency of 400 Hz to 10 kHz downhole in the presence of a metal hydrogenation catalyst that causes the water in the crude oil to react and form hydrogen which then hydrotreats and upgrades the heavy crude oil during production. In another embodiment, if the heavy crude oil does not contain water, the hydrogen may be formed in-situ by contacting the heavy crude oil downhole with a chemical compound comprising ammonia, hydrazine and formic acid that in the presence of a metal hydrogenation catalyst and sonic energy causes the chemical compound to react and form hydrogen which then hydrotreats the heavy crude oil during production. Suitable catalysts include nickel on zinc dust, platinum on carbon and palladium on carbon, preferably nickel on zinc dust. The hydrotreated and upgraded heavy crude oil has improved properties making it easier to refine and transport by pipeline. The upgrading includes reducing the amount of asphaltenes and resins in the heavy crude oil and increasing the amount of aromatics and saturates.
    • 含有至少1重量%水的重质原油在生产井中生产井下时进行加氢处理和升级。 在生产过程中,在金属加氢催化剂存在下,含水的重质原油在400Hz至10kHz的低频率下经受声能,其导致原油中的水反应并形成氢气,然后进行加氢处理和升级 生产中的重质原油。 在另一个实施方案中,如果重质原油不含水,则可以通过使井下的重质原油与包含氨,肼和甲酸的化合物接触来原位形成氢,所述化合物在金属氢化催化剂存在下和 声能导致化合物反应并形成氢气,然后在生产过程中对重质原油进行加氢处理。 合适的催化剂包括锌粉上的镍,碳上的铂和碳上的钯,优选在锌粉上的镍。 加氢处理和升级的重质原油具有改进的性质,使其更容易通过管道精炼和运输。 升级包括减少重质原油中沥青质和树脂的数量,增加芳烃和饱和物的用量。

    • A method is described for the preparation of chalcogenides of ruthenium, rhodium, osmium and iridium transition metals of the Periodic Table of the Elements which comprises mixing in the absence of an aqueous solvent a Group VIII transition metal salt with a source of chalcogenide, said chalcogenide being selected from the group consisting of sulfur, selenium, tellurium and mixtures thereof, yielding a precipitate of the formula MX.sub.y wherein M is selected from the group consisting of ruthenium, rhodium, osmium and iridium, X is sulfur, selenium, tellurium and mixtures thereof and y is a number ranging from about 0.1 to about 3, preferably 0.1 to about 2.5. By the practice of the nonaqueous synthesis technique, Group VIII chalcogenides are prepared which are finely divided, have a high surface area, small particle size and small crystallite size which are also free of excess sulfur, water and/or hydrolysis products. This technique also permits the preparation of a heretofore unobtainable composition, layered stoichiometric osmium disulfide. The precipitates which result as a consequence of the instant process may be cleansed of any anion salt coproduct by any technique common to the art, pumping under vacuum being one such technique, washing with a suitable solvent being another.Compounds of the formula MX.sub.y wherein M, X and y are as defined above, prepared by the low temperature, nonaqueous precipitation technique herein disclosed are superior sulfur-tolerant catalysts in catalytic processes, for example, hydrodesulfurization, hydrodenitrogenation, hydroconversion, hydrogenation.
