Abstract [en]

Synthetic amorphous silicas with high porosity (94–97%) are introduced and various pathways for their synthesis are presented. The materials have structures with high surface area (300–750 m2/g) and are commercialised under the name of Quartzene®. Low cost silica sources and ambient pressure drying enable production in large scale with approximately 70% cost reduction as compared to conventional method silica aerogels. The structure is analysed, properties are reported as low density (0.04–0.15 g/ml), low thermal conductivity (24–26 mW/m·K), etc. Formaldehyde gas adsorption tests reveal that the uptake level of samples made by Quartzene® is significantly increased as compared to commercially available adsorbents. Thermal conductivity at elevated temperatures for mixtures of Quartzene® and stone wool shows a 23% reduction at 650 °C as compared to pure stone wool. Scaling up process for this green material meeting environmental sustainability demands in industrial manufacturing is discussed and challenges/current developments are presented.

Abstract [en]

During last years the interest in large scale production of nano/mesoporous materials has increased in the industry due to benefits that these materials can provide. Silica based nanomaterials are examples of such materials with large specific surface area and pore volume where the porous structure is the key for the resulting properties leading to efficiency in e.g. filtration applications.

The aim of this research was to contribute knowledge on understanding the porous structure and its relation to the efficiency. For this approach, the porous structure of a nano/mesoporous silica-based material is characterized. The analysis of this material is a challenge as it has a wide range of pores in the structure from a few nanometres to several micrometres. Electron microscopy (EM) methods are used for the structural analysis of the materials as a complementary method to nitrogen adsorption (NA). The samples are analysed as powders and the relation between the structure and efficiency in the application is discussed.

Through this research different synthesis pathways have been studied under the family name of Quartzene®, and the differences in the resulting structure is discussed. The synthesis and storage conditions have been varied in order to study the effect on the porous structure.
