Method for transforming a gas mixture into a gas mixture of higher added value, comprising a step of injecting a gas mixture into a pulsed plasma reactor, a dissociation step using pulsed discharges to generate a shock wave between two electrodes to produce gases, and a step of releasing the produced gases to an area where they can be cooled down and/or separated and/or collected. The dissociation step is also designed to provide passive re-ignition of the plasma in the event that the latter is blown out by the continuous stream of gas in the reactor.

A universal chemical processor (UCP) including a reactor vessel having a central longitudinal axis and main chamber comprises a first inlet port for a main feedstock, a second inlet port for a fluidizing medium and a third inlet port for one or more reactants. The UCP also includes a reactive radioactive chemical processor (R.sup.2CP) that contains a radioactive element positioned extending along the longitudinal axis in the main chamber. In operation, a fluidized bed can be supported in the main chamber when a fluidizing medium and feedstock are supplied to the main chamber through the first and second inlet ports and the radioactive element of the R.sup.2CP emits ionizing radiation that is capable of ionizing feedstock and reactants, inducing chemical reactions, and sterilizing and decomposing any organic materials within a radiation zone.

A device and a process to propagate molecular growth of hydrocarbons, either straight or branched chain structures, that naturally occur in the gas phase of a first gas to gas phase molecules of a second gas having higher molecular chain lengths than the hydrocarbons of the first gas. According to one embodiment, the device includes a grounded reactor vessel having a gas inlet, a product outlet, and an electrode within the vessel; a power supply coupled to the electrode for creating an electrostatic field within the vessel for converting the first gas to a second gas.
