A method for activating chemical reactions using a non-thermal capillary discharge plasma (NT-CDP) unit or a non-thermal slot discharge plasma (NT-SDP) unit (collectively referred to as “NT-CDP / SDP”). The NT-CDP / SDP unit includes a first electrode disposed between two dielectric layers, wherein the first electrode and dielectric layers having at least one opening (e.g., capillary or a slot) defined therethrough. A dielectric sleeve inserted into the opening, and at least one second electrode (e.g., in the shape of a pin, ring, metal wire, or tapered metal blade) is disposed in fluid communication with an associated opening. A non-thermal plasma discharge is emitted from the opening when a voltage differential is applied between the first and second electrodes. Chemical feedstock to be treated is then exposed to the non-thermal plasma. This processing is suited for the following exemplary chemical reactions as (i) partial oxidation of hydrocarbon feedstock to produce functionalized organic compounds; (ii) chemical stabilization of a polymer fiber (e.g., PAN fiber precursor in carbon fiber production; (iii) pre-reforming of higher chain length petroleum hydrocarbons to generate a feedstock suitable for reforming; (iv) natural gas reforming in a chemically reducing atmosphere (e.g., ammonia or urea) to produce carbon monoxide and Hydrogen gas; or (v) plasma enhanced water gas shifting.

A method is provided for the thermo-neutral reforming of liquid hydrocarbon fuels which employs a Ni, Ce2O3, La2O3, Pt−ZrO2, Rh and Re catalyst having dual functionalities to achieve both combustion and steam reforming.

One exemplary embodiment of the present invention can be a hydrocarbon conversion process. The process may include passing a hydrocarbon stream through at least one heater including at least one burner, a radiant section, and a convection section. Generally, the stream passes through the radiant section and then through the convection section before exiting the heater. Desirably, the hydrocarbon stream includes, in percent or parts by weight based on the total weight of hydrocarbons in the stream:C4 or less: less than about 0.5%,sulfur or sulfur containing compounds: less than about 1 ppm, andnitrogen or nitrogen containing compounds: less than about 1 ppm.Preferably, the sulfur or sulfur containing compounds and the nitrogen or nitrogen containing compounds are measured as, respectively, elemental sulfur or nitrogen.

A process is presented for increasing the aromatics content in a reformate process stream. The process modifies existing processes to change the operation without changing the reactors or heating units. The process includes bypasses to utilize heating capacity of upstream heating units, and passes the excess capacity of the upstream heating units to downstream process streams.
