Title:
CATALYST FOR DIESEL OIL OXIDATION DISTILLATION ULTRA DEEP DESULFURATION, ITS PREPARATION AND DESULFURATION METHOD
Document Type and Number:
WIPO Patent Application WO/2009/062390
Kind Code:
A1
Abstract:
An amphiphilic oxidation catalyst for diesel oil oxidation distillation ultra deep desulfuration, its formula is Qm[XMnOq],Wherein: 1 ≤ m ≤ 12; 9 ≤ n ≤ 18,34 ≤ q ≤ 62; and Q is a quaternary ammonium salt; X is P, Si, As or B; and M is Mo or W. A method for diesel oil oxidation distillation ultra deep desulfuration, comprises: a) fully mixing diesel oil, the amphiphilic oxidation catalyst, and hydrogen peroxide at ambient temperature and atmospheric pressure, and reacting for 10-300 minutes, and converting sulfide in diesel oil to sulfone to obtain an oxidative diesel oil; b) subjecting the oxidative diesel oil to decompression distillation to obtain an ultra-low sulfur diesel oil having sulfur content of less than 10 ppm; and c) recycling the catalyst and the sulfone.
