Patent Searching and Data


Document Type and Number:
Japanese Patent JPS5515514
Kind Code:
B2
Abstract:
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.
