Abstract

Reducing the sulfur content of fuels is a topical issue for all fuels. One feature is to use adsorptive reduction. Several Ca containing adsorbents can be used for this purpose, including bentonite and fly ash. However, the problem is to separate the adsorbent from the treated oil so that no adsorbent solids particles remain in the oil. The invention belongs to the field of oil shale oil industry and deals with a method for reducing sulfur in oil shale oil, obtained by thermal decomposition of oil shale. The invention involves pumping oil shale oil through a reactor containing an Ca containing adsorbent and an active metal (Fe, Mg, Al, Zn) powder at normal pressure or overpressure up to 5 atmospheres and at a temperature of 200-400 ° C, where the processed shale oil is removed from the adsorbent as a vapor gas mixture. During the process, in addition to the binding sulfur to the adsorbent particles and metal powder, the physicochemical properties of the shale oil as viscosity and density, are also improved.
