Test of column-type commercial reactor in production of oxidized asphalts from residua from West-Siberian crudes

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

Summary

  1. 1.

    Feasibility has been demonstrated for the use of a column-type apparatus as an oxidation reactor in the production of road and builder's asphalts.

  2. 2.

    The column-type reactor is a high-capacity apparatus. With a high rate of air feed to the oxidation, in the production of road asphalts, the oxygen is almost completely consumed; when producing builder's asphalts, the free oxygen content of the oxidation gases reaches 7–9%.

  3. 3.

    The system that was used for removing the heat of reaction in residuum oxidation — the introduction of water onto the surface of the product being oxidized — was effective in maintaining the required temperature regime for the oxidation.

  4. 4.

    For the road asphalts produced from West-Siberian crudes in the column-type reactor, those with penetrations at 25°C not greater than 100–110 (x0.1 mm) have better heat and cold resistance than similar asphalts oxidized in batch oxidation stills. For the asphalts with higher penetrations the method of production has hardly any effect on quality.

    The high-softening-point asphalts (BN-IV and BN-V) produced in the column have better heat and cold resistance than those produced in the stills.
