Abstract: A granular catalyst suitable for sweetening sour petroleum distillates consists of 35-45 per cent by weight of water, 4-15 per cent of cupric chloride, and the remainder fuller's earth. The catalyst is prepared by adding an aqueous solution of cupric chloride to the required amount of fuller's earth. The cupric chloride solution may be obtained by dissolving cupric sulphate and ammonium or sodium chloride in water. The fuller's earth support may be a natural or acid-treated adsorbent clay, e.g. Attapulgus clay. The sour oil is contacted with the catalyst in the presence of free oxygen, for example by the slurry process at about 100 DEG F. The catalyst is especially suitable for use with distillate oils containing oxygenated polar compounds, e.g. phenols; such oils are thermally cracked distallates, virgin distillates containing thermally cracked distillates, and virgin distillates of high sulphur content. Before treatment the sour oil may be washed twice with aqueous caustic soda to remove hydrogen sulphide and then with water, or may be extracted twice with acid, neutralized with caustic soda and water-washed. Tests are described which show that the colour stability of the sweetened oils is improved, and the loss of copper from the catalyst is decreased, as compared with processes using catalysts of lower water content or prepared by different methods. It is not necessary to use hot water to wash the treated oil, one washing with water at 34 DEG F. being sufficient.
