摘要： A method is provided for controlling the operating temperature of a catalytic reactor using a closed-loop system that provides for varying the reactor input and other operating parameters in order to maintain the operating temperature of the reactor at or near the initial setpoint temperature for operation of the reactor. In one example, maximum and minimum operating temperatures with a catalytic partial oxidation reactor are controlled, as well as maintaining control over the corresponding minimum required ratio of oxygen atoms to carbon atoms, such that the operating temperature within the reactor is maintained below the material limits but above threshold temperatures for coking.

摘要： A fuel reformer includes a reforming portion having a tubular catalytic converter that is composed of a substrate supporting the catalytic component, and is arranged to have a center axis extending along the supply direction of the fuel and oxidizer derived from a supply portion, and a communication passage arranged along an inner wall of the catalytic converter and communicating with the supply portion. The fuel and oxidizer supplied from the supply portion to the communication passage pass from the inner wall of the catalytic converter to an outer wall thereof by forced convection, thereby reforming the fuel.

摘要： An apparatus and process for vaporizing and, optionally, igniting a liquid fuel, preferably, a distillate fuel. The apparatus includes the following components: a heat-conductive reticulated screen positioned within a chamber; a first inlet path into the chamber for delivering a liquid fuel onto the screen; a second inlet path into the chamber for contacting an oxidant with the screen and fuel; a means for heating the screen to a temperature sufficient to vaporize and, optionally, ignite the liquid fuel; and a recuperator in fluid communication with the chamber for transferring heat from the chamber to the second inlet path. The apparatus is suitably employed in compact and portable oxidation reactors, for example, in external combustion engines, catalytic partial oxidation reformers, and hybrid combustors operating in flame and/or catalytic modes.

摘要： The invention provides a method for transferring heat by conduction to the internal heat acceptor of an external combustion engine. Fuel and air are introduced and mixed to form an air/fuel mixture. The air/fuel mixture is directed into a catalytic reactor that is positioned substantially adjacent to the heater head. Heat is transferred via conduction from the catalytic reactor to the heater head and the catalytic reaction products are exhausted.

摘要： A process of catalytic partial oxidation of a hydrocarbon fuel, such as diesel, with an oxidant, such as air, to produce a partially-oxidized reaction product, such as a hydrogen-containing fuel gas, with simultaneous in-situ coke removal. The process involves feeding a hydrocarbon fuel and an oxidant to a reactor in a fuel-rich feed ratio; reacting the fuel and oxidant for a fuel-rich cycle-time so as to produce a partially-oxidized reaction product; varying the fuel feed, or the oxidant feed, or both feeds to produce a fuel-lean feed to the reactor; maintaining the fuel-lean feed for a fuel-lean cycle-time sufficient to reduce coke deposits while maintaining a substantially constant yield of partially-oxidized reaction product; and alternating between the fuel-rich and fuel-lean operating cycles.
