Abstract: A process for converting hydrocarbon feedstock into olefins and BTX including feeding a hydrocarbon feedstock to a first hydrocracking unit, feeding effluent from the first hydrocracking unit to a first separation section to be separated, feeding a steam including propane to a dehydrogenation unit, and feeding effluent from the dehydrogenation unit to a second separation section.

Abstract: The present invention relates to a process for converting a high-boiling hydrocarbon feedstock into lighter boiling hydrocarbon products, said lighter boiling hydrocarbon products being suitable as a feedstock for petrochemicals processes, said converting process comprising the following steps of: feeding a hydrocarbon feedstock having a boiling point of >350 deg Celsius to a cascade of hydrocracking unit(s), feeding the bottom stream of a hydrocracking unit as a feedstock for a subsequent hydrocracking unit, wherein the process conditions in each hydrocracking unit(s) are different from each other, in which the hydrocracking conditions from the first to the subsequent hydrocracking unit(s) increase from least severe to most severe, and processing the lighter boiling hydrocarbon products from each hydrocracking unit(s) as a feedstock for one or more petrochemicals processes.
