The reaction rate of hydrocarbon pyrolysis can be increased to produce solid carbon and hydrogen by the use of molten materials which have catalytic functionality to increase the rate of reaction and physical properties that facilitate the formation and contamination-free separation of the solid carbon. Processes, materials, reactor configurations, and conditions are disclosed whereby methane and other hydrocarbons can be decomposed at high reaction rates into hydrogen gas and carbon products without any carbon oxides in a single reaction step. The process also makes use of specific properties of selected materials with unique solubilities and/or wettability of products into (and/or by) the molten phase to facilitate generation of purified products and increased conversion in more general reactions.

Simultaneous reaction and separation of chemicals

A multi-junction artificial photosynthetic unit includes an active element with a plurality of semiconducting layers, with metal layers deposited between the semiconductor layers appropriately forming Schottky barrier junctions or ohmic junctions with a surface of an adjacent semiconductor layer. The active element is formed within a protective structure formed of porous aluminum oxide. Successive layers of the active element can be formed within the protective structure, and additional layers and junctions can be added until desired photovoltages are achieved. A photoreactor for the production of fuels and chemicals driven by solar-powered redox reactions includes a bag reactor filled with a feedstock solution. A plurality of multi-junction photosynthetic units are placed in the feedstock solution to drive the redox reactions and produce the desired fuels and chemicals.

Multi-junction artificial photosynthetic cell with enhanced photovoltages

Described herein are multi-dimensional networks that can include a recurring unit of Formula (I) and a recurring unit of Formula (II), and methods of synthesizing and using the same.

Multi-dimensional networks

A photoelectrosynthetically active heterostructure (PAH) is manufactured by forming or providing cavities in an electrically insulating material; forming or providing an electrically conductive layer on a side of the electrically insulating material; depositing an electrocatalyst cathode layer in the cavities; depositing one or more layers of light-absorbing semiconductor material in the cavities; depositing an electrocatalyst anode layer in the cavities; removing the layer of electrically conductive metal; and forming a hydrogen permeable layer over the electrocatalyst cathode layer. The one or more layers of light-absorbing semiconductor material can form a p-n junction or Schottky junction. The PAH can be used in photoelectrosynthetic processes to produce desired products, such as reduction product (e.g., methane gas, methanol, or carbon monoxide) from carbon dioxide and liquid waste streams.

Methods for manufacturing photoelectrosynthetically active heterostructures

A two-step process, consisting of a photoelectrosynthetic process combined with a thermochemical process, is configured to produce a reduction product (e.g., methane gas, methanol, or carbon monoxide) from carbon dioxide and liquid waste streams. In a first step, photoelectrosynthetically active heterostructures (PAHs) and sunlight are used to drive oxidation/reduction reactions in which one primary product is hydrogen gas. In the second step, hydrogen generated in the first step is thermally catalytically reacted with carbon dioxide to form a reduction product from carbon dioxide (e.g., CO, formaldehyde, methane, or methanol). Synthesis gas (CO and H) can be further reacted to form alkanes. The methods and systems may employ PAHs known in the art or improved PAHs having lower costs, improved stability, solar energy conversion efficiency, and/or other desired attributes as disclosed herein.

Photoelectrosynthetically active heterostructures

A process is disclosed that includes brominating a C, C, C, Cor Calkane with elemental bromine to form a bromo-alkane. The bromo-alkane is reacted to form a C, C, C, Cor Calkene and HBr. The HBr is oxidized to form elemental bromine.

Conversion of propane to propylene

A method comprising providing a halogen stream; providing a first alkane stream; reacting at least a portion of the halogen stream with at least a portion of the first alkane stream to form a halogenated stream, wherein the halogenated stream comprises alkyl monohalides, alkyl polyhalides, and a hydrogen halide; providing a second alkane stream; and reacting at least a portion of the second alkane stream with at least a portion of the alkyl polyhalides to create at least some additional alkyl monohalides.

Continuous process for converting natural gas to liquid hydrocarbons

A method comprising: providing a first halogen stream; providing a first alkane stream; reacting at least a portion of the first halogen stream with at least a portion of the first alkane stream in a first reaction vessel to form a first halogenated stream; providing a second alkane stream comprising Cand higher hydrocarbons; providing a second halogen stream; and reacting at least a portion of the second halogen stream with at least a portion of the second alkane stream in a second reaction vessel to form a second halogenated stream.

Improvements in previously disclosed methods of and apparatuses for converting alkanes, alkenes, and aromatics to olefins, alcohols, ethers, and aldehydes includes: safety improvements, use of alternative feedstocks, process simplification, improvements to the halogenation step, improvements to the reproportionation step, improvements to the solid oxide reaction, improvements to solid oxide regeneration, improvements in separations, maintenance, start-up, shut-down, and materials of construction.

Hydrocarbon conversion process improvements

A process is provided for separating one or more light gases from bromine or chlorine using one or more physical separations and contact with a chemical scrubber to recover additional halogen. In one aspect, the process comprises (a) providing a feed of halogen containing one or more light gases to a distillation column or flash vaporizer; (b) operating the distillation column or flash vaporizer to separate the feed into (i) a first liquid containing a major amount of halogen and no more than a minor amount of light gas(es), and (ii) a first vapor containing a major amount of light gas(es) and no more than a minor amount of halogen; and (c) providing the vapor to a chemical scrubber to recover halogen from the vapor.

Separation of light gases from halogens

An improved continuous process for converting methane, natural gas, or other hydrocarbon feedstocks into one or more higher hydrocarbons or olefins by continuously cycling through the steps of alkane halogenation, product formation (carbon-carbon coupling), product separation, and regeneration of halogen is provided. Preferably, the halogen is continually recovered by reacting hydrobromic acid with air or oxygen. The invention provides an efficient route to aromatic compounds, aliphatic compounds, mixtures of aliphatic and aromatic compounds, olefins, gasoline grade materials, and other useful products.
