  • Patent number: 10851036
    Abstract: Systems and methods are provided for direct methane conversion to methanol. The methods can include exposing methane to an oxidant, such as O2, in a solvent at conditions that are substantially supercritical for the solvent while having a temperature of about 310° C. or less, or about 300° C. or less, or about 290° C. or less. The solvent can correspond to an electron donor solvent that, when in a supercritical state, can complex with O2. By forming a complex with the O2, the supercritical electron donor solvent can facilitate conversion of methane to methanol at short residence times while reducing or minimizing further oxidation of the methanol to other products.

  • Publication number: 20100051246
    Abstract: A high-temperature and high-pressure corrosion-resistant process heat exchanger for a nuclear hydrogen production system decomposes sulfite (SO3) using heat from a high-temperature gas-cooled reactor to thereby produce sulfide (SO2) and oxygen (O2). The process heat exchanger comprises second and third system coolant channels, each of which is defined by a heat transmission fin, which is bent in a quadrilateral shape, and heat transmission plates, and has increased corrosion resistance thanks to ion-beam coating and ion-beam mixing using a material having high corrosion resistance. The third system coolant channel includes reaction catalysts for SO3 decomposition, and is made of a super alloy. Thus, a system differential pressure between the second and third system coolant channels can be greatly maintained at a high temperature of 900° C. or higher.

    Abstract: A system for generating hydrogen includes a liquid metal nuclear reactor having a non-radioactive secondary heat loop, a steam generator connected to the secondary heat loop, a high temperature water cracking system, and a topping heater. The heat produced by the nuclear reactor is used to raise the temperature of the feed water for the cracking system to between about 450° C. to about 550° C. The topping heater raises the feed water temperature from the 450° C. to 550° C. range to at least 850° C. so that the cracking system can operate efficiently to produce hydrogen and oxygen.

  • Patent number: 4816211
    Abstract: A nuclear excited power system includes a gaseous core nuclear reactor through the core of which helium is passed. The helium is excited by the high energy radiation from the nuclear reactor and is coupled to a reaction chamber wherein the high energy helium mixes with hydrogen and a halogen, such as, chlorine. The energy thus transferred to the hydrogen and chlorine causes the hydrogen and chlorine to combine to form a hydrogen chloride plasma. The high temperature, high pressure hydrogen chloride plasma drives a turbine, magnetohydrodynamic generator or other electromechanical device to form electrical and/or mechanical energy. The helium and hydrogen chloride exhaust products are separated with the helium coupled back to the reactor core. The hydrogen chloride is disassociated and coupled back to the reaction chamber.
