A photochemical methane-conversion platform designed to transform methane-rich and renewable gas feedstocks into hydrogen, C₂ hydrocarbons, LPG-range hydrocarbon fractions and recoverable process energy through a controlled UV–mercury photosensitisation pathway.
The platform integrates feed conditioning, UV–Hg photochemical conversion, product recovery, purification and methane recycle into a single process architecture.
UV excitation creates excited mercury species that transfer energy to methane, initiating gas-phase radical chemistry.
The technology combines photochemical activation with multi-product methane valorisation and integrated recovery pathways.
The project development range is approximately 120–400°C, providing a lower-temperature reaction window than conventional high-temperature methane conversion routes.
The core reaction is based on UV-driven gas-phase free-radical photochemistry rather than conventional catalytic surface chemistry.
UV photons excite mercury, enabling energy transfer to methane and initiating methane C–H bond activation.
The architecture is designed around hydrogen and C₂ hydrocarbon products, with potential LPG-range hydrocarbon fractions and recoverable process energy.
Unreacted methane and mercury recovery are incorporated into the process architecture to support controlled recycle and resource utilisation.
The technology is being developed from laboratory validation towards prototype and pilot-scale integrated demonstration.
Mercury is used as a photosensitiser within the photochemical reaction system. Under UV irradiation, mercury is excited and acts as an energy-transfer medium for methane activation.
It is not intended to be consumed as a conventional reactant. The technology architecture incorporates controlled mercury recovery and recycle.
UV radiation excites mercury atoms. The excited mercury species then transfer energy to methane, initiating the radical chemistry responsible for hydrogen and C₂ hydrocarbon formation.
Mercury vapour recovery, condensation and recycle are incorporated into the downstream process architecture.
Instead of treating methane conversion as a single-product hydrogen process, the platform is designed to explore multiple value streams.
H₂ generated through methane C–H activation and subsequently separated and purified.
H₂ Energy StreamC₂H₆ formed through methyl-radical coupling and available as an intermediate hydrocarbon stream.
C₂ Chemical IntermediateC₂H₄ can be obtained through downstream ethane conversion, creating a route towards polymer and chemical value chains.
C₂H₄ Chemical PlatformThe platform also targets identification and recovery of C₃–C₄ hydrocarbon fractions subject to experimental validation.
Potential C₃–C₄ StreamThe technology architecture considers both chemical-product formation and the thermal energy generated or available within the process.

Mercury absorbs UV energy and reaches an excited state.

Multi-product platform
The long-term platform vision is to increase the value recovered from every unit of methane entering the process.
Hydrogen, C₂ products, LPG-range hydrocarbons and process-energy recovery create multiple potential value streams.
The platform is designed to work with methane-rich renewable and waste-derived feedstocks such as biomethane and CBG.
C₂ hydrocarbons provide a pathway from methane towards higher-value chemical and polymer feedstock applications.
The architecture aims to retain more of the carbon entering the reactor within useful product streams.
Blue Rats is developing a next-generation photochemical platform that connects methane valorisation, hydrogen production, C₂ chemistry, LPG-range hydrocarbon recovery and energy integration within one technology architecture.
