Title:
PROCESS FOR THE DEMERCAPTANIZATION OF PETROLEUM DISTILLATES
Document Type and Number:
WIPO Patent Application WO2001042392
Kind Code:
A3
Abstract:
The demercaptanization of petroleum distillates can be carried out by sorption of the mercaptan with activated carbon and oxidation of the sorbed mercaptan to disulfide at between approximately 20 DEG C to 55 DEG C. The activated carbon used in the process is commercially readily available. Its surface area typically ranges from between approximately 500 to 1500 m<2>/g and has substantial percentage of the pores in the 10 to 100 Angstrom range.
