  • Combined process for the separation and continuous coking of high softening point asphaltenes
    Patent number: 4859284
    Abstract: The present invention relates to a combined process for separating and converting asphaltenes of high molecular weight and high softening point from heavy hydrocarbon material containing asphaltenes by a process that combines a deasphalting method to produce solid asphaltenes and a continuous coking procedure for the solid asphaltenes. The combined process converts the material into more valuable liquid hydrocarbon products of lower molecular weight and coke.
