System for dehumidification of a vehicle interior

An integrated power generation system including: a hotbox containing a steam reformer and at least one solid oxide fuel cell (SOFC) stack; a condenser, a combustor, a heater, and a turbomachine comprising a compressor and an expander. The steam reformer is configured to convert a hydrocarbon fuel and steam into a stack fuel. The SOFC stack is configured to convert the stack fuel into a first anode waste gas. The condenser functions to remove water from the first anode waste gas, thereby producing a second anode waste gas of higher fuel energy density. The combustor burns the second anode waste gas with release of exothermic heat. The heater thermally transmits heat from an expanded combustion product to water collected in the condenser, so as to generate steam. A steam line fluidly connects the heater to the steam reformer.

Integrated power generation system

A process for hydrogen recovery from refinery gas system comprising supplying the refinery gas to an inlet manifold fluidly coupled to a conditioning stage, the conditioning stage comprising a reactor having a reforming catalyst deposited on an ultra-short-channel-length metal substrate; supplying oxidant to the conditioning stage via the inlet manifold; supplying steam from a steam generator to the conditioning stage via the inlet , manifold; reacting the refinery gas in the conditioning stage; and discharging a product through a discharge outlet fluidly coupled to the conditioning stage, the discharge outlet configured to flow the product for use by a downstream reformer. The process allows to either increase the H2 production rate or lower the firing rate while maintaining a constant H2 production rate for the downstream steam reformer, independent of the feed compositional variability of the refinery or still gas.

Refinery gas processing method

A thermophotovoltaic generator incorporating a two-stage combustor for providing heat to a thermophotovoltaic cell. Combustor parts include a partial oxidation reactor, which functions catalytically to convert a hydrocarbon fuel and a first supply of an oxidant into a gaseous partial oxidation product; and further include downstream thereof, a deep oxidation reactor including a premixer plenum fluidly connected to a heat spreader comprising a porous matrix, such as a ceramic foam. Functionally, the deep oxidation reactor converts the gaseous partial oxidation product and a second supply of oxidant into complete combustion products. Heat produced by the two-stage combustor generates radiative energy from a photon emitter, which is directly converted to electricity in a photovoltaic diode cell.

Two-stage combustor for thermophotovoltaic generator

A thermally integrated hotbox apparatus combining a steam reformer, a plurality of solid oxide fuel cell (SOFC) stacks, a plurality of oxidant manifolds, and at least one heat extractor. The steam reformer occupies a central position in the hotbox, around which are disposed in spaced-apart relation a plurality of SOFC stacks. A burner may be associated with the steam reformer, either within or outside the hotbox. An oxidant manifold is disposed between each pair of adjacent SOFC stacks. A heat exchanger is incorporated between an SOFC stack and an oxygen manifold. The hotbox design optimally captures thermal heat from the SOFC stacks for use in producing steam and operating the endothermic steam reformer. The apparatus reduces duty cycle of the burner, which produces heat and steam needed for operation of the endothermic steam reformer.

An individual solid oxide cell (SOC) constructed of a sandwich configuration including in the following order: an oxygen electrode, a solid oxide electrolyte, a fuel electrode, a fuel manifold, and at least one layer of mesh. In one embodiment, the mesh supports a reforming catalyst resulting in a solid oxide fuel cell (SOFC) having a reformer embedded therein. The reformer-modified SOFC functions internally to steam reform or partially oxidize a gaseous hydrocarbon, e.g. methane, to a gaseous reformate of hydrogen and carbon monoxide, which is converted in the SOC to water, carbon dioxide, or a mixture thereof, and an electrical current. In another embodiment, an electrical insulator is disposed between the fuel manifold and the mesh resulting in a solid oxide electrolysis cell (SOEC), which functions to electrolyze water and/or carbon dioxide.

Regenerative solid oxide stack

A portable, compact, real-time and accurate sensor and method for deriving a physicochemical property of a liquid fuel, such as cetane number, carbon content, carbon/hydrogen (C/H) atomic ratio, or heating value (net heat of combustion). The sensor comprises a constant-volume ignition chamber equipped for measuring ignition delay and magnitude of a peak rise in pressure or temperature following dispensation of a liquid fuel into the chamber. The sensor utilizes air at atmospheric pressure and microliter quantities of fuel. The sensor can be implemented in real-time refinery operations for blending diesel fuels that meet government mandated cetane number standards as well as in applications for standardizing jet, biodiesel, and synthetic fuels, which presently are not classified by any physicochemical property.

Sensor for determining a physicochemical property of a liquid fuel

A two-stage combustor having as constituent parts: a partial oxidation reactor, which catalytically converts a hydrocarbon fuel and a first supply of oxidant into a gaseous partial oxidation product; and a deep oxidation reactor having a premixer plenum fluidly connected to a porous heat spreader, which converts the gaseous partial oxidation product to deep oxidation products. In one embodiment, the premixer plenum provides an empty space wherein combustion occurs in flame mode. In a second embodiment, the premixer plenum contains a high pore density foam matrix, absent catalyst, which facilitates holding a flameless combustion downstream within the porous heat spreader. In both embodiments heat produced during combustion is transmitted from the heat spreader to an associated heat acceptor, such as a heater head of a Stirling engine.

A spark-ignited (SI) internal combustion (IC) engine designed to operate on high octane fuels, such as gasoline, is reconfigured to operate on low octane fuels including logistically preferred distillate fuels, such as diesel or JP-8. Design modifications involve coupling a fuel reformer module to the internal combustion engine. Auxiliary components include a system control module, a heat exchange module, a bypass valve to facilitate start-up, and/or a throttle body to control a reformate-oxidizer mixture fed to the engine. Small portable generators having 0.3-3.0 kWe power output are disclosed based upon the modified SI-IC engine design.
