FLUID CATALYTIC CRACKING PROCESS TECHNOLOGY
The modern petroleum refinery has a series of core process units that create clean gasoline and low sulfur diesel fuel. The first oil refinery unit is crude oil desalting. The desalter removes salt, water and other contaminants from crude oil prior to distillation in an atmospheric tower.
Oxidative desulfurization of synthetic diesel using
Results and discussion. The efficiencies of oxidative desulfurization of diesel were up to 99% and the sulfur concentration of diesel after desulfurization can drop to 10 ppm. These results suggest that ultra-deep desulfurization of diesel can be achieved by ODS process in presence of vanadia-based catalysts.

US10351778B2 - Systems for producing anode grade coke from
Methods and systems for producing anode grade coke are disclosed, which allow anode grade coke to be produced from crude oil having a high sulfur content. A fraction of the resid is hydrotreated while another fraction of the resid is treated in a solvent deasphalting unit. A synthetic stream is provided by blending hydrotreated resid with one or more streams from the deasphalting unit.
(PDF) Production of diesel-like fuel from waste engine oil
Production of diesel-like fuel from waste engine oil by pyrolitic distillation. From these results, the CaO with a ratio of 2% has the highest effect on decreasing of sulfur content of the waste engine oil and on acquiring the most suitable distillation temperatures close to values of a diesel fuel. Diesel-like fuel (DLF) is obtained as 60% of the waste lubrication engine oil.
