High-pressure hydrotreating of petrolatum from mixed Zhirnovsk and Korobki crudes

  • Published:
Chemistry and Technology of Fuels and Oils Aims and scope

Summary

  1. 1.

    By hydrotreating a petrolatum from mixed Zhirnovsk and Korobki crudes at a pressure of 300 kg/cm2, feed-stock space velocity of 0.5 h−1, hydrogen-rich gas 750 volumes per volume of feedstock, and temperatures of 360− 400°C on alumina-cobalt-molybdenum catalyst or 340–370°C on alumina-nickel-molybdenum catalyst, white petrolatum can be obtained without any breakdown of the paraffinic-naphthenic hydrocarbons.

  2. 2.

    From a comparison of the results obtained in hydrogenating petrolatum on both types of catalysts, it has been shown that the alumina-nickel-molybdenum catalyst manifests a somewhat greater hydrogenating activity, but at the same time gives more cracking and isomerization.

  3. 3.

    The hydrotreated petrolatum is a high-quality raw material for the production of highly treated ceresins and waxes.
