METHOD FOR PURIFYING MINERAL OIL FRACTIONS AND DEVICE SUITABLE FOR CONDUCTING SAID METHOD

摘要

Disclosed is a method for reducing the organic sulfur content in a sulfur-containing liquid fuel, wherein the sulfur-containing fuel is first brought in contact with a hydrogen-containing gas in a presaturator and subsequently the hydrogen-enriched liquid fuel is brought in contact with a suitable adsorbent in a reactor. The adsorbent is able to adsorb at least part of the sulfur and/or of the sulfur compound from the fuel at the surface. The contact with the adsorbent can advantageously take place not only at higher temperatures of approximately 400° C., but also at moderate temperatures, as low as room temperature, because the use of liquid fuel ensures very good contact between the fuel and the surface of the adsorbent, and therefore ensures reduction of the sulfur content.
