OUR TECHNOLOGY

Continuous, Industrial-scale, Cost-effective
Nanomaterial Manufacturing

It’s all about scale

Promethean operates the largest continuous multi-material nanomaterial manufacturing plant in the world. Our proprietary and patented process is key to our ability to manufacture industrial scale, cost-effective nanomaterials – two of the primary barriers that have long held-back the potential of these incredible materials. We have transformed the manufacture of high-quality MOFs and inorganic nanomaterials, taking them from academic novelty and research to industrial viability.

Continuous flow hydrothermal synthesis (CFHS)

In simple terms, we combine two streams of raw materials at two different temperatures. These come together in our patented counter-current reactor and lead to the formation of solid nanomaterials.. This allows us to manufacture the nanomaterials directly as a dispersion in water or other liquid.

Our CFHS process has demonstrated that the continuous production of nanomaterials leads to better and more consistent quality, increased scale, better cost-effectiveness and improved safety.

Industrial Scale, Cost-effective Nanomaterials

The primary benefit of our process is that it finally delivers the industrial scale, cost-effective nanomaterials that real-world applications demand.

Our scalable continuous flow process is different from traditional batch ones in that it can generate identical nanomaterial products at a variety of production scales, with little variation in particle size or morphology.

The relatively small reactor volume, even at large production scale, allows access to high temperature and pressure reaction conditions without the high costs normally associated with heating a large batch pressure vessel. This allows us to offer a wide range of nanomaterials, particularly MOFs, which have traditionally not been available at industrially relevant scales.

The materials produced using Promethean’s technology are generated as dispersions in a carrier solvent (predominantly water), which allows for easy post-processing and avoids the agglomeration often seen when dry powderbased methods are used. This allows for easy incorporation of nanomaterials into multi-material formulations, unlocking a wider range of applications for these novel materials

Optimised Process,
Optimised Products

Thanks to our continuous flow process and patented reactor designs, we have transformed manufacture of high-quality, inorganic nanoparticles, making cost -effective, industrial-scale production.possible.

Distinctive
Dispersions

Our unique process initially delivers nanomaterials as a dispersion, allowing us to retain more of the intrinsic properties of both MOFs and nanoparticles. Our dispersion-based chemistry provides for greater downstream flexibility and safe handling.

Enabling Sustainable,
Circular Solutions

Our nanomaterials are being used to break through the performance limits in carbon capture, thermally efficient heat transfer, additive manufacturing, and carbon-based fuel alternatives, as well as coatings, inks and pigments, batteries, and more.
