摘要:
The present invention is a Solid Oxide Fuel Cell Reforming Power System that utilizes adiabatic reforming of reformate within this system. By utilizing adiabatic reforming of reformate within the system the system operates at a significantly higher efficiency than other Solid Oxide Reforming Power Systems that exist in the prior art. This is because energy is not lost while materials are cooled and reheated, instead the device operates at a higher temperature. This allows efficiencies higher than 65%.

摘要:
The efficiency and effectiveness of apparatuses for vaporizing and combusting liquid fuel can be improved using thermal conductors. For example, an apparatus having a liquid fuel vaporizer and a combustion chamber can be characterized by a thermal conductor that conducts heat from the combustion chamber to the vaporizer. The thermal conductor can be a movable member positioned at an insertion depth within the combustion chamber that corresponds to a rate of heat conduction from the combustion chamber to the vaporizer. The rate of heat conduction can, therefore, be adjusted by positioning the movable member at a different insertion depth.
摘要:
Apparatus for vaporizing liquid in a vaporization pathway having an actively controlled temperature are disclosed according to some aspects. The apparatus can comprise a first body having a cross sectional shape and dimensions substantially equal to the cross sectional shape and dimensions of a cavity in a second body, which allows the first body to be non-permanently inserted into the second body. The outer surface of the first body, the inner surface forming the cavity in the second body, or both can be modified to create a vaporization pathway between the first and second bodies when the surfaces mate and/or align. The liquid vaporizer can further comprise a vaporization pathway inlet for fluid comprising liquid, a vaporization pathway outlet for fluid comprising primarily vapor, and a heater in thermal communication with the first body, the second body, or both. The heater provides active control of the temperature of the vaporization pathway.

摘要:
Mercaptoalkylalkoxysilane is obtained by reacting at least one sulfide of the general formula MHS wherein M is an alkali metal or ammonium with a haloalkyl silane in an aqueous reaction medium in the presence of an acidic gas to maintain the pH of the reaction medium at or below about 10, and in the additional presence of alkylguanidinium salt phase transfer catalyst to provide mercaptoalkylalkoxysilane, the alkylguanidinium salt phase transfer catalyst being represented by the general formula: wherein each of R1-5 is a primary alkyl radical and R6 is a primary alkyl or bis(primary alkylene) radical, or at least one of the R1–R2, R3–R4 and R5–R6 combinations with the respective connecting nitrogen atom forms a heterocyclic radical; X is an anion; and n is 1 or 2.
摘要:
A fluid treatment system incorporating an integrated heat exchanger and thermal treatment unit. A fan draws or pushes a contaminated fluid through the heat exchanger, which is preferably of the counter flow type. The integrated heat exchanger and thermal treatment unit is fabricated by stacking sheets of metal foil so that gaps are defined between adjacent sheets. These gaps define alternating untreated and treated fluid channels. The untreated fluid flows through the heat exchanger and into the thermal treatment unit, with is disposed within aligned orifices formed in the metal foil sheets. Heat transfer occurs between adjacent treated and untreated channels, which greatly improves the efficiency with which a temperature of the untreated fluid entering the heat exchanger is changed as a result of heat transfer with the treated fluid that is exiting the heat exchanger. A header system is in fluid communication with either all of the treated or all of the untreated fluid channels. The integrated heat exchanger and thermal treatment unit also usable as a chemical reactor to generate a desired chemical product from at least one reactant.
