Hydrogenation Methods Refine Heavy Oil Stock

摘要

The catalytic cracking of vacuum distillate which had not undergone any preliminary desulfurization makes it possible to produce gasoline cuts,containing 0.25-0.40 mass percent of sulfur and diesel oil cuts,containing 1.5-2.0 mass percent of sulfur. Taking into account toughening ecological requirements to the indicated products (in perspective - not more than 50 ppM - Euro standard 4 and not more than 10 ppM - Euro standard 5),it is necessary to perform deep desulfurization of the initial vacuum distillate or additional hydrotreatment of the produced gasoline and diesel distillates.
