A process can be used for performing a pyrolysis of hydrocarbons in a rotary drum reactor at a temperature in the range of from 600 to 1800° C. The heat for the endothermic pyrolysis is provided by resistive heating of at least one particulate electrically conductive material introduced into said rotary drum reactor and moved through the rotary drum reactor with a flow of a hydrocarbon. The rotary drum reactor contains (A) an inner wall made of electrically insulated material, (B) a pressure-bearing outer wall, and (C) an electrical heating system attached to the inner wall and/or at least one integrated electrically conducting electrode pair. The at least one electrode pair is located at both ends of the inner wall of the rotary drum.

A hybrid steam cracking process including, in addition to combusting a fuel in a steam cracker furnace to provide thermal energy to the radiant and convection sections, heating a segment of an external furnace piping using an electrical heating device. The external furnace piping can include, e.g., the hydrocarbon-containing feed inlet piping, the cross-over piping, the radiant section inlet piping, and the radiant section outlet piping. Capacity and selectivity of the steam cracker furnace can be enhanced compared to conventional steam cracking process without electrical heating. The technology can be conveniently deployed in existing conventional steam cracking facilities.

System, apparatuses, and methods for processing feedstock have a decomposing stage for breaking down feedstock into liquid and gaseous products and a condensing stage for condensing gaseous products to a liquid condensate. A mixing stage can also be used to combine gaseous and liquid feedstock portions into a combined liquid feedstock to be fed to the decomposing stage. The decomposing stage can be one or more flux tanks having a field generator for creating an electromagnetic field through the flux tank configured to decompose feedstock inside. The condensing stage can have a catalyst tank, distillation tank, condensing pipes, or a combination thereof. The mixing stage can be a reformer device having pairs of plates, at least some of the plates are capable of rotating to generate a shear force that creates a cavitation effect to combine the gaseous and liquid feedstock portions.
