The present invention relates to crude oil processing, particularly related to conversion of crude oil containing high amount of naphthenic acid compounds to lighter hydrocarbon materials with minimum capital expenditure. The invented process utilizes a novel scheme for high TAN crude oils by employing thermal cracking process to maximize the residue conversion to valuable products, which require minimum modifications in unit metallurgies and corrosion inhibitor injection schemes in refineries.

A process for the cracking of a carbon-containing feedstock to produce olefins includes contacting, in a reactor system, the carbon-containing feedstock with oxygen gas in the presence of a molten salt matrix consisting of a eutectic mixture of alkali metal carbonates, alkaline earth metal carbonates, or a mixture of any two or more thereof, to generate an olefin-containing product stream; and collecting an olefin from the olefin-containing product stream; wherein: the oxygen is fed with the carbon-containing feedstock in a gas stream comprising from greater than 0 wt % to about 21 wt % oxygen in an inert gas; the process is conducted in the absence of a catalyst comprising a transition metal, a transition metal oxide, a rare-earth metal, a rare earth metal oxide, or a combination of any two or more thereof; and the process is conducted in the absence of a glass-forming oxide.
