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

摘要

Elemental sulfur present in fluids such as refined petroleumproducts, e.g., gasoline, jet, diesel, kerosene or fuel additives such asethers, isremoved from such fluids by contacting the contaminated fluid with anadsorbentof Mg2AlNO3 or Mg3AlNO3 or by adding to the fluids a quantity ofhydro-carbyl mercaptan and passing the resulting mixture through an adsorbentselectedfrom the group consisting of alumina, bayerite, brucite and hydrotalcite likematerials of the formula M x 2+ M y 3+ (OH)2x+3y-z (NO3) MH2O wherein M2+is Magnesium, M3+ is aluminum, and x, y and z are values from 1 to 6 and m isthe number of waters of hydration.
