Currently, refiners are experiencing a big challenge due to the slow economic growth, over diesel production anddecreased demand of it. Refineries are searching for technologies that could reduce diesel output, particularly theinferior light cycle oil (LCO) fraction. Here in, this article mainly we will describes the industrialized technologies forLCO processing such as LCO upgrading, LCO blending into available plants such as fluid catalytic cracking (FCC),and hydro-refining/treating unit, LCO moderate hydrocracking, and LCO to some aromatic rich stream and also withgasoline with the integration of selective hydro-refining and resulting optimized FCC unit. It is analyzed that the LCOmoderate hydrocracking can provide more gasoline at the expense of high H2 consumption, while LCO to aromaticsand gasoline (LTAG) technology needs more steps for clean fuel production and retrofitting of FCC plant. Based onthe analyses of current technologies, it is suggested that implementation of such technologies should consider theconfiguration of refineries, as well as the benefit of end users.
