METHOD FOR DESULFURIZATION OF HEAVY OIL

摘要

A method for the desulfurization of a heavy oil, which comprises diluting a heavy oil with a dilution medium to 90 mass % or less, and an operation of subjecting the resultant diluted heavy oil to a decomposition treatment with a decomposition rate of 10 % or less. The above method can be used for prolonging the life of a catalyst in a process for the desulfurization of a heavy oil.
