Abstract: The present application relates to a process for cracking a hydrocarbon feedstock, using to the largest extent electrically powered equipment where the power is obtained from renewable sources or low-carbon sources. In particular, it relates to a process for cracking a hydrocarbon feedstock, including bringing the hydrocarbon feedstock and dilution steam to supersonic velocities in the reactor, followed by applying a shockwave to induce cracking of the hydrocarbon feedstock, to convert at least a part of the hydrocarbon mixture to produce olefins.
