SULFUR REMOVAL FROM HYDROCARBON FLUIDS BY MIXING WITH ORGANO MERCAPTAN AND CONTACTING WITH HYDROTALCITE-LIKE MATERIALS, ALUMINA, BAYERITE OR BRUCITE

摘要

Elemental sulfur and sulfur contaminants causing silver corrosionand present in fluids such as refined petroleum products, e.g., gasoline, jet,diesel, kerosene or fuel additives such as ethers, is removed from such fluidsbycontacting the contaminated fluid containing indigenous hydrocarbyl mercaptanor by adding to the fluids which lack or have insufficient indigenoushydrocarbylmercaptan a quantity of hydrocarbyl mercaptan and passing the resultingmixturethrough an adsorbent selected from the group consisting of alumina, bayerite,brucite and hydrotalcite like materials of the formula M x2+ M y3+ (OH)2X+3y-z(NO3) mH2O wherein M2+ is magnesium, M3+ is aluminum, and x, y and z arevalues from 1 to 6 and m is the number of waters of hydration.
