Abstract: Heavy hydrocarbon oils are effectively desulfurized with minimum hydrogen consumption by being contacted with a hydrodesulfurization catalyst under desulfurization conditions including a temperature between 750*F. and 850*F. and a space velocity between 3 and 10 v/v/hr.

Abstract: Heavy hydrocarbon oils are desulfurized at high temperature and high space velocity in the presence of a catalyst comprising a Group VIII metal and a Group VI metal or their compounds and also containing as an agent for reducing the deactivation rate of the catalyst, a small amount of a Group VII metal or compound thereof.

Abstract: A sulfur-containing oil is initially preoxidized with an oxidant, such as, an organic peroxide, an organic hydroperoxide, air or an organic peracid in the presence of a Group IV-B, Group V-B or VI-B metal catalyst, water is then added to the preoxidized oil and desulfurization is carried out with sodium oxide, potassium oxide or calcium oxide catalyst on an alumina support. Water is added to the oil prior to desulfurization at a concentration ranging from 1 to 20 percent by weight.
