USE OF CATALYST WITH BASE OF MOLYBDENUM FOR DIRECT OXIDATION AT LOW TEMPERATURE OF SULPHUROUS COMPOUNDS INTO SULPHUR AND/OR SULPHATES

摘要

The invention relates to the use, for thedirect oxidation of sulphur compounds to sulphur and/orsulphates at low temperature, of catalysts comprisingan active phase including molybdenum and a supportbased on titanium dioxide, zirconia, silica, silica-alumina or alumina, the said silica, silica-alumina andalumina exhibiting a specific surface of at least20 m[err]/g and a total pore volume of at least 0.3 cm[err]/g.
