摘要： Low sulfur-content petroleum oil stocks are prepared by contacting a sulfur-containing oil stock with an alkali metal, preferably sodium, or an alkali metal alloy, preferably sodium/lead, thereby producing a mixture comprising a low sulfur content oil containing alkali metal salts dispersed therein. The alkali metal treating step is conducted in the presence of low pressure hydrogen, i.e., 25 to 500 psig. The resulting mixture is then treated with either water or H2S thereby disengaging a substantial portion of the salts from the oil. The salt phase is then blended with a molten sulfur-rich alkali metal polysulfide thereby forming a sulfur-depleted alkali metal polysulfide which is subsequently decomposed electrolytically to form alkali metal.

摘要： LOW SULFUR-CONTENT PETROLEUM OIL STOCKS ARE PREPARED BY CONTACTING A SULFUR-CONTAINING OIL STOCK WITH AN ALKALIMETAL, PREFERABLY SODIUM, OR AN ALKALI METAL ALLOY, PREFERABLY SODIUM/LEAD, TO PRODUCE A MIXTURE COMPRISING A LOW SULFUR CONTENT OIL CONTAINING ALKALI METAL SALT DISPERSED THEREIN. THE MIXTURE OF SALTS IN OIL IS RESOLVED BY CONTACTING THE SAME, IN ONE EMBODIMENT OF THE INVENTION, WITH 10-80 MOLE PERCENT H2O BASED ON TOTAL MOLES OF SALT IN THE OIL, AT A TEMPERATURE OF AT LEAST ABOUT 610* F., WHEREUPON A SALT PHASE SEPARATES FROM THE OIL. IN A SECOND EMBODIMENT OF THE INVENTION, THE CONTACTING IS CONDUCTED WITH ABOUT 110-200 MOLE PERCENT H2O, AT A TEMPERATURE RANGING BETWEEN ABOUT 500-750* F. IN A LATTER EMBODIMENT, THE WATER-TREATED MIXTURE IS SUBSEQUENTLY COOLED TO BELOW ABOUT 250* F. THUS SEPARATED THE SALT IS BLENDED WITH A MOLTEN SULFUR-RICH ALKALI METHAL POLYSULFIDE AND H2S THEREBY FORMING A SULFUR-DEPLETED ALKALI METHA POLYSULFIDE WHICH IS THEN DECOMPOSED ELECTROLYTICALLY TO FORM ALKALI METAL AND A SULFUR-RICH POLYSULFIDE, WHICH IS SUBSEQUENTLY REDUCED IN SULFUR CONTENT.

摘要： LOW SULFUR-CONTENT PETROLEUM OIL STOCKS ARE PREPARED BY CONTACTING A SULFUR-CONTAINING OIL STOCK WITH AN ALKALI METAL, PREFERABLY SODIUM, OR AN ALKALI METAL ALLOY, PREFERABLY SODIUM/LEAD, TO PRODUCE A MIXTURE COMPRISING A LOW SULFUR OIL AND A MIXTURE OF ALKALI METAL SALTS DISPERSED THEREIN. THE MIXTURE OF SALTS IN OIL IS RESOLVED BY CONTACTING THE SAME WITH, PREFERABLY, 30-160 MOLE PERCENT HYDROGEN SULFIDE BASED ON TOTAL MOLES OF SALT IN THE OIL, A TEMPERATURE OF ABOUT 670* F. OR ABOVE WHEREUPON A SALT PHASE SEPARATES FROM THE OIL. THUS SEPARATED THE SALT IS BLENDED WITH A MOLTEN SULFUR-RICH ALKALI METAL POLYSULFIDE THEREBY FORMING A SULFUR-DEPLETED ALKALI METAL POLYSULFIDE AND LIBERATING HYDROGEN SULFIDE. IN ANOTHER EMBODIMENT OF THE INVENTION. MOLTEN SULFUR MAY BE USED IN PLACE OF THE POLYSULFIDE. THE SULFUR-DEPLETED POLYSULFIDE IS THEN DECOMPOSED ELECTROLYTICALLY TO REFORM ALKALI METAL AND A SULFUR-RICH POLYSULFIDE, FROM WHICH ELEMENTAL SULFUR IS RECOVERED.
