Provided is a conversion process for an organic oil, relating to the field of biomass utilization, energy and chemical industry. The conversion process is carried out in presence of an aqueous slurry and a catalyst selected from the group consisting of an iron oxide compound, a waste agent resulting from use of an iron oxide compound as desulfurizer, and a regeneration product of the waste agent, under a controlled molar ratio of iron element to sulfur element. It is found that free radical condensation polymerization of organic oil during cracking process can be blocked effectively by using carbonylation, and hydrogenation is achieved with active hydrogen produced from the conversion of CO and water. In the conversion process, organic material, especially biomass solid, can be directly converted without dehydration, and water can be additionally added to the biomass liquid or the mineral oil.

Summary

The object of the invention is a method for producing naphthenic process oils that have a high content of naphthenic carbon atoms of 20-60 wt % and a low content of polycyclic aromatics of less than 3 wt %, determined in accordance with IP 346, by the hydrogenation of a process oil educt that has a high content of polycyclic aromatics. The method in accordance with the invention enables secondary extracts, such as are formed in the production of label-free process oils, even in a mixture with primary extracts, to be utilized in an economically meaningful way. The resulting process oils are likewise label-free, so that the use of PCA-containing process oils can be reduced and less of these substances will get into the environment. Through this the environment and in particular health are less stressed. In addition, the starting substances in this way can lead to a different use and no longer have to be added to heating oil. By avoiding heating oil, CO.sub.2 emissions are also reduced. Also, through the direct hydrogenation of DAE, high value naphthenic process oils are obtained by the method in accordance with the invention. The process oils that are obtained contain surprisingly high amounts of naphthenic hydrocarbon compounds. In addition, an object of the invention is the use of the process oils produced in accordance with the invention as a plasticizer or extender oil for natural and synthetic rubber mixtures or thermoplastic elastomers.
