NOVELTY - The system has a reaction tube structure comprising an outer wall made of dielectric material. The tube structure is configured such that lateral dimension of the tube structure extends through a slot in a position that is perpendicular to a primary axis of a waveguide, where energy is propagated to the tube structure to form a plasma within the tube structure and process gas to react and form into a product stream when hydrocarbon feedstock from a feedstock source and process gas from process gas source (107) are fed into the tube structure and energy is received in the waveguide.    USE - System for processing fossil hydrocarbon materials used for petroleum/liquid fuel products. Uses include but are not limited to coal, bitumen, oil sands, tar sands, oil shale, petroleum resids, resins, asphaltenes, pre-asphaltenes and vitrinite and kerogen-containing materials.    ADVANTAGE - The system allows energy to be propagated to the tube structure to form the plasma within the tube structure and cause the feedstock and process gas to react and form into a product stream when hydrocarbon feedstock from the feedstock source and process gas from process gas source are fed into the tube structure and the energy is received in the waveguide so as to satisfy converting and upgrading hydrocarbon fuel products requirement in an effective manner.    DETAILED DESCRIPTION - The process gas source is selected from a group consisting of helium, argon, krypton, neon, xenon, methane, propane, butane, ethane, acetylene, propylene, butylene, ethylene, carbon monoxide, carbon dioxide, water vapor, hydrogen and nitrogen. The hydrocarbon feedstock source is composed of coal, bitumen, oil sands, tar sands, oil shale, petroleum resids, asphaltenes, pre-asphaltenes and other vitrinite or kerogen-containing materials. An INDEPENDENT CLAIM is also included for a method for processing hydrocarbon materials.    DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of a system for processing hydrocarbons.
