Pilot scale production of aerogels produced at BASF Lemförde. Pictures: BASF Lemförde

NanoHybrids started on 1st November 2015 to develop a new generation of nanoporous organic and hybrid aerogels for industrial applications. Main objective has been the upscaling from laboratory to pilot scale production.

After 42 months NanoHybrids reached its main goals: a number of novel bioabased, organic and hybrid aerogel particles can now be produced in pilot scale for the first time. The combination of experiments and modelling resulted in improved production processes with defined parameters.

Main achievements can be summarized as follows:

  • Production of different types of aerogel particles with Jet Cutter technology and emulsion technique
  • Production of bio-aerogel particles by emulsion technique and continuous solvent exchange in 50 L scale
  • Modelling of different steps of aerogel production processes established
  • Process of supercritical drying of aerogel particles in industrial scale firstly proved
  • Prototypes are being tested

The knowledge has been made available for further research and development via a number of open access publications and reports. The project ended on 30 April 2019.

Jet Cutter Technology as new production method for large amounts of aerogel beads identified by NanoHybrids https://nanohybrids.eu/html/news/jet-cutter-technology-as-new-procution-method-for-large-amounts-of-aerogel-beads-identified-by-nanohybrids/ Tue, 30 Apr 2019 14:56:09 +0000 https://nanohybrids.eu/html/?p=2151 ]]>

NanoHybrids achieved the production of bio-based aerogel beads in industrial scale for the first time. Two main methods have been developed, tested and employed. On one hand, well-known emulsion-gelation has been transferred into a continuous process especially suitable for small aerogel beads; on the other hand, the jetcutting method has been identified as a potential continuous production method for biopolymer-based aerogels with larger size. Production throughput of both methods can be upscaled to industrial scale.

JetCutter technology

The JetCutter, developed and produced by geniaLab GmbH, Brunswick, is a particle production technology for the synthesis of monodisperse beads. The production process is easy, clean and flexible. With minor changes a wide range of bead diameters from few 100 µm to several millimeters can be achieved. Bead generation frequencies can be as high as 9000 beads per second and nozzle. Depending on the final bead diameter throughputs up to 72 kg/h can be achieved. The JetCutter is a reliable technology for elegant scale-up from lab-scale to production-scale.

Bio-based aerogel bead production via Jet Cutting technology

Production of alginate beads via the jet cutting method has been reported before; however, they were not converted into aerogels. In the course of NanoHybrids, several poly-saccharide-based aerogel beads have now been produced, e.g. with amidated pectin, sodium alginate, and chitosan as precursors. JetCutting followed by gelation, solvent exchange and supercritical drying with carbon dioxide resulted in the formation of spherical aerogel particles with narrow particle size distributions in the range of 400 to 1500 µm and a specific surface area of around 500 m2/g.

How the jet cutting method works:

Throughout the jet cutting method, a liquid jet of biopolymer solution is cut by a rotating cutting disc. Obtained liquid cylinders fall along their trajectory to the ground. Throughout falling, due to surface tension cylinders form spheres, liquid drops are collected at the end of the particle trajectory. 

Application potential

Polysaccharide aerogel beads with their physical, chemical and functional properties can be used in applications such as separation techniques, catalysis or as carriers for drug delivery. Often, spherical shape of the particles is desirable due to easier handling and application.

With the aim to reduce energy consumption, the biopolymer-based aerogel particles synthesized by NanoHybrids were tested as humidity absorbers in drying units for home appliances, particularly for dishwasher. It has been shown that for several cycles of absorption and desorption of humidity, aerogel particles are stable with an absorption capacity of around 20 wt. %.

Moreover, foodgrade production of alginate aerogels is also possible with the JetCutter, thus enabling aerogels for food applications.

The Pilot Plant at TUHH – European solution for aerogel tech. translation – Fact Sheet https://nanohybrids.eu/html/news/the-pilot-plant-at-tuhh-european-solution-for-aerogel-tech-translation-fact-sheet/ Thu, 25 Apr 2019 07:00:56 +0000 https://nanohybrids.eu/html/?p=2069 ]]> About the TUHH pilot plant

The TUHH pilot plant for aerogel production comprises of two high-pressure units (64 L & 25 L capacity) to perform the supercritical carbon dioxide drying needed for aerogel production.
The unit is enclosed in a ventilated cabin satisfying the ATEX norms. Each unit is operated independently in closed loop setting with carbon dioxide recycling. Aerogel particles, beads and monoliths can be processed (100‘s of liters) for product prototyping.
Customized aerogel processing and parameter settings investigations can also be carried out upon request.

Supercritical carbon dioxide drying

Supercritical carbon dioxide drying is a methodology that allows to remove the solvent inside the gel without collapsing the intrinsic pore structure of the gel network. Several industrially available solvents such as ethanol, propanol, methanol, acetone, ethyl-acetate, DMSO and others can be extracted with this technique. The modern version of supercritical carbon dioxide drying is carried out between 40-65 °C and 90-120 bar pressure. The drying time mainly depends on the gel dimensions, gel chemistry and the solvent choice. Initial supercriticalcarbon dioxide drying feasibility tests with proprietary formulations can be checked upon request.

Aerogel processing

Aerogel production is a three step process involving
1. Gel production
2. Solvent exchange (for water based gels)
3. Supercritical carbon dioxide drying
Gels can be processed as particles (<100 μm), beads (0.1-3.0 mm) or in monolithic form.

If gels are processed in solvents incompatible with supercritical carbon dioxide (example: water); solvent exchange to a compatible solvent (example: ethanol) is necessary. Solvent recycling (>95 %) feasibility can also be demonstrated with ethanol-water systems.

Foodgrade Aerogels – Intelligent nutrient and drug release – Fact Sheet https://nanohybrids.eu/html/news/foodgrade-aerogels-intelligent-nutrient-and-drug-release-fact-sheet/ Wed, 24 Apr 2019 07:00:56 +0000 https://nanohybrids.eu/html/?p=2062 ]]> Alginate and cellulose based aerogels proved to be appropriate for the application in the food sector: edibility, renewability, sustainability and relatively low cost of these polysaccharides make them an attractive starting material of functional food. The aqueous biopolymer solutions can easily be processed to highly porous networks without the need and production of health endangering substances. For instance, the substance requirements for the production of small alginate particles are limited to calciumcarbonate, acetic acid, ethanol and rapeseed oil.

Properties and advantages

Small (1 – 30 μm) and spherical aerogel particles are advantageous for consumption, particularly for a comfortable mouthfeel during chewing and swallowing.
The accessibility of the pores and the affinity of the surface to flavors, drugs and other functional ingredients are important factors for the application of aerogels as additives in food and as drug delivery systems. The controlled drug release depends on factors such as pH dependent swelling and dissolution, which contribute to the overall release kinetics. Furthermore, release profiles vary on network density and cross-linking degree allowing the precise modulation of release kinetics. Drug delivery kinetics may also be varied by the application of coating on the particle’s surface.

Application potential

Perhaps the most studied application area suggested for polysaccharide aerogels is drug delivery, as aerogels may serve as a hosting matrix for active compounds and nutraceuticals. In food formulations, polysaccharide aerogels could also function as dietary fibre (e.g., cellulose) or as a source of energy. They can also be utilized as mechanical support structures in food packaging and water absorbents in active packaging.

Bio-aerogels are one of the classes of aerogel materials that exhibit open-porous nanofibrillar network. They are based on natural polymers such as polysaccharides or proteins. Bio-aerogels are produced by sol-gel synthesis via biopolymer dissolution followed by chain self-assembly and drying with supercritical carbon dioxide. No toxic compounds or processes are involved in bio-aerogel synthesis, and thus they are “humanfriendly” materials. In the frame of Nanohybrids project, alginate, cellulose, chitosan and their composite aerogels were prepared on a large scale as particles either by emulsion or Jet-Cutter techniques.

Properties and advantages

Bio-aerogels possess amazing properties such as high porosity (>90 %), very low density and high specific surface area (200-500 m2/g). Particle size can vary from few microns to few millimeters.

Application potential

Bio-aerogels can be used as classical aerogels: for thermal insulation, in separation, adsorption and absorption and in catalysis. A strong advantage is that bio-aerogels can also be used in food and feed, in cosmetics and bio-medical and pharma applications as scaffolds, matrices for drug delivery, etc.
