摘要： A method for removing sludge from a petroleum storage tank is based on a two-step approach utilizing solvent extraction to dissolve organic components of the sludge followed by water wash to remove inorganic materials. Sludges contain both organic-based solids (e.g., waxes and asphaltenes) as well as inorganic-based solids (known to exist as salts such as chlorides, carbonates, and oxides). The organic components of the sludge are dissolved using petroleum-based solvent streams that have been identified to possess high solvent power. The dissolved material can then be processed and recovered in the refinery using conventional refining operations. A water wash following removal of the organic materials is effective to remove the inorganic materials that can then be disposed of without the complications of the having to treat the oily organics along with them. A beneficial part of the method includes mixing and heating to improve the dissolution of soluble materials in both steps of the process.

摘要： The present invention relates to a continuous in-situ process for the removal from heavy oils, of organically bound sulfur in the form of mercaptans, sulfides and thiophenes, heteroatoms selected from the group consisting of nitrogen and oxygen and metals selected from the group consisting of nickel, vanadium and iron, comprising the steps of (a) contacting a heavy oil with aqueous sodium hydroxide at a temperature of about 380.degree. to about 450.degree. C. for a time sufficient to form sodium sulfide; (b) contacting said sodium sulfide of step (a) with water and a transition metal for a time and at a temperature sufficient to form transition metal sulfide, sodium hydroxide, hydrogen and impurities; and (c) recirculating said sodium hydroxide from step (b) to step (a) and removing said transition metal sulfide and said impurities, wherein said impurities are iron, vanadium and nickel. Optionally, molecular hydrogen may be added in the first step. The present invention is useful in removing organically bound sulfur that has been recognized to be difficult to remove, such as thiophenes. Beneficially, the process also removes other heteroatoms (nitrogen and oxygen) and metals (vanadium, iron, nickel) and reduces asphaltene content (n-heptane insolubles), micro concarbon residue, coke, 975.degree. F. fractions, TGA fixed carbon, average molecular weight, density and viscosity.

摘要： This invention is directed to a process for pretreating coal preliminary to a primary liquefaction or hydroconversion block. In the process, a coal feed, slurried in a solvent, is reacted with carbon monoxide in the presence of a chemical promoter at an elevated temperature and pressure. The promoter enhances the depolymerization and hydrogenation of the coal during pretreatment.
