Fields of application

Catalytic process of carbonaceous raw material conversion for the production of hydrogen of fuel and energy purpose.

Concise description

High temperature proton conductive materials could be used as component of membrane catalysts for the production of hydrogen with fuel and energy purpose.

Expected gain

The application of the proton conductive material as the part of membrane catalyst for the process of hydrothermal conversion of low-grade coal raw material will help to generate a directed flow of particles Н+ and ОН–. It will ensure keep stable the high activity of the catalyst gasification and improve the technological parameters of the process.

Advantage

The developed organic polymers and their composites own the injected proton conductivity at the level of 10-5?10-4 Sm/cm and high thermal and moisture resistance in the temperature range of 100-460 °C in an inert and reductive atmosphere.

Development Status

It were developed the new proton conductive materials based on the synthesized polymers of polyene, polybenzimidazole and polyparaphenylene terephthalamide polymers and their composites.
Polyene proton conductive materials were synthesized by oxidative dehydropolycondensation of acetylene and dehydrochlorination of polyvinylchloride at inert atmosphere. Physicochemical studies showed that the synthesized polyene polymer comprises the polymer fragments with the system of conjugated or cumulated multiple bonds between carbon atoms in the chain.
Polybenzimidazoles were received by the way of dehydropolycondensation of dihydrate 3,3'-diaminobenzidinetetraclorine and isophthalic acid. The composites of polymers in different weight ratio were prepared by grinding, mixing and subsequent compression.
The study of proton conductivity in reduced and inert atmosphere shows that the developed composites in the temperature range of 100-460 °C have injected proton conductivity at the level of 10-5 ? 10-4 S/cm and high thermal and moisture resistance. The mechanism of injected proton conductivity is related to the structure of polymers and composites.
The doping of the polymer composites with inorganic additives of perovskite or layered structure makes it possible to stabilize the proton transport along the organic chains.
