Induction heating of endothermic reactions
A reactor system for carrying out an endothermic catalytic chemical reaction in a given temperature range upon bringing a reactant into contact with a catalyst material. The reactor system includes a reactor unit arranged to accommodate catalyst material including one or more ferromagnetic macroscopic supports susceptible for induction heating where the one or more ferromagnetic macroscopic supports are ferromagnetic at temperatures up to an upper limit of the given temperature range. The one or more ferromagnetic macroscopic supports are coated with an oxide, and the oxide is impregnated with catalytically active particles. The reactor system moreover includes an induction coil arranged to be powered by a power source supplying alternating current and being positioned so as to generate an alternating magnetic field within the reactor unit upon energization by the power source, whereby the catalyst material is heated to a temperature within the temperature range by the alternating magnetic field.

A furnace for gas fields, refineries reforming, petrochemical plants, or hydrogen generation by gasification may include: a radiant zone; a convective zone; and a first and second series of pipes through which at least two segregated process gas flows respectively pass. A first process gas flow may enter the furnace through the convective zone and, flowing through the first series of pipes, may leave the furnace through the radiant zone, or alternatively the first process gas flow may enter the furnace through the radiant zone and, flowing through the first series of pipes, may leave the furnace through the radiant zone. At least a second process gas flow may enter the furnace through the convective zone, may pass through the second series of pipes, and may leave the furnace through the convective zone. The second of series of pipes may be made of material resistant to acid gases.
HYDROTHERMAL PROCESS FOR PRODUCING HYDROGEN
Systems and methods for generating hydrogen from water consisting of reacting aluminum alloy powders with steam in the presence of an effective amount of promotor are provided. Aluminum powder is premixed with a dry solid-state promotor mixture before being exposed to high-temperature steam. Steam is introduced into a vessel called reactor, where the aluminum powder premixed with optimal ratio of promotors is contacted at pressure and temperature conditions to help the reaction between aluminum powder and water occurs completely, with 100% conversion in less than 15 minutes. Since the reaction occurs at high temperature condition, the heat released from the exothermic reaction between aluminum and steam is a “high-quality” heat, contributing to excess heat separation and making the most of the reaction heat, producing steam.
CATALYTIC REACTOR SYSTEM AND CATALYST FOR CONVERSION OF CAPTURED C02 AND RENEWABLE H2 INTO LOW-CARBON SYNGAS
The present invention describes an improved catalytic reactor system with an improved catalyst that transforms CO.sub.2 and low carbon H.sub.2 into low-carbon syngas with greater than an 80% CO.sub.2 conversion efficiency, resulting in the reduction of plant capital and operating costs compared to processes described in the current art. The inside surface of the adiabatic catalytic reactors is lined with an insulating, non-reactive surface which does not react with the syngas and effect catalyst performance. The improved catalyst is robust, has a high CO.sub.2 conversion efficiency, and exhibits little or no degradation in performance over long periods of operation. The low-carbon syngas is used to produce low-carbon fuels (e.g., diesel fuel, jet fuel, gasoline, kerosene, others), chemicals, and other products resulting in a significant reduction in greenhouse gas emissions compared to fossil fuel derived products.
Syngas generation for gas-to-liquid fuel conversion
A syngas generator is disclosed as an exothermic gas generator that can accommodate high combustion temperatures of a natural gas/oxygen flame. The generator consists of four sections: a heavily insulated combustion chamber, a catalyst chamber, a spray chamber, and a heat exchanger. These four sections may be arranged in series and tightly bolted together to form a gas-tight system. Natural gas, oxygen and steam are supplied to a burner at the inlet end of the combustion chamber. This mixture is ignited and the resulting hot process gas is then fed into a catalyst bed where it reacts with the steam and is converted to carbon monoxide and hydrogen (syngas). The syngas is fed to a Fischer-Tropsch unit to create liquid fuel.

A flow reactor system for providing on-demand H.sub.2 evolution at pressure from a liquid organic hydrogen carrier and/or blends thereof includes a reactor that includes a reaction vessel having an inlet and outlet. The inlet is configured to introduce reactants into the reaction vessel, and the outlet is configured to release reaction products. The reaction vessel is configured to hold therein a catalyst system capable of catalyzing the evolution of molecular hydrogen from a liquid organic hydrogen carrier. Advantageously, the reaction vessel is configured to operate at pressures greater than or equal to 50 psig (e.g., from about 50 psig to about 10500 psig. The flow reactor system also includes a source of preheated liquid organic hydrogen carrier in fluid communication with the reactor and a purification system in fluid communication with the outlet that provides purified molecular hydrogen gas for on-demand applications.
STARTUP METHODS FOR OXIDATION REACTOR
In a reactor for partial oxidation of feedstock employing a hot oxygen stream that is generated by a suitable burner, the same burner that generates and provides the hot oxygen stream in full-scale partial oxidation operation can be employed in the starting-up of the partial oxidation reactor by suitable control of the characteristics of the feed to the burner, or of the pressures.
