The mutual effect of group components during coking

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

Summary

  1. 1.

    Addition of oils retards coke formation from asphaltenes. These in turn accelerate the decomposition of the oils.

  2. 2.

    Owing to the mutual effect of the components, a mixture of asphaltenes and oils behaves during coking like a single component with intermediate properties (tars).

  3. 3.

    The kinetics of the coking of complex mixtures of group components, such as (say) a mixture of bitumen and cracking residue, can be described approximately by the equations derived for coking of tars.

  4. 4.

    A relation has been found between the velocity constants calculated from the topochemical equation and those calculated from the sequential condensation reaction.

  5. 5.

    The mutual effect of the group components during coking involves not only the process kinetics but also the structure of the cokes and graphites.

  6. 6.

    Recycling of the intermediate decomposition products is recommended for viscracking and coking.
