The invention relates to a process for the exploitation of oil shales wherein the two main contituents threreof, organic and inorganic moieties, are transformed into valuable products, It was found that oil shales which possess a high amount of inorganic constituents, as well as than mineral part resulted from the combustion of oil shales, have a catalytic effect on the cracking of ~ heavy fraction of fuel, producing valuable fractions of hydrocarbon fuel. According to the process, a mixture of oil shales which possess a low portion of organic moiety, is cracked at a temperature in the range of 350 to 600.degree.C with a fraction of heavy fuel having a boiling point of above 350.degree.C. From the gases going out from the cracking reactor, a hydrocarbon fuel having a boiling point of up to 350.degree.C is recovered. The residue resulted in said crac- king is useful as a raw material in the chemical industry.
