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 corrosion and present in fluids such as refined petroleum products, e.g., gasoline, jet, diesel, kerosene or fuel additives such as ethers, is removed from such fluids by contacting the contaminated fluid containing indigenous hydrocarbyl mercaptan or by adding to the fluids which lack or have insufficient indigenous hydrocarbyl mercaptan a quantity of hydrocarbyl mercaptan and passing the resulting mixture through 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)m H2O wherein M2+ is magnesium, M3+ is aluminum, and x, y and z are values from 1 to 6 and m is the number of waters of hydration.
