Highly water-stable zeotype structure able to withstand hydrothermal conditions

Posted by Markus from ClariantResponsive · Innovative Products and Technologies · Switzerland

Summary of the technology

Zeolites are aluminosilicate crystals. Their unique structures consist of well-defined channels and pores. These channels make zeolites excellent choices for a variety of applications in catalysis and adsorption. With their high surface area and porosity on a molecular dimension, zeolites behave as molecular sieves: they allow small molecules to pass through, and stop larger molecules.

The proprietary material contains titanium and phosphorus within the framework. The zeotype structure is able to withstand hydrothermal conditions, and contrary to the isostructural SAPO-34, it is highly stable in the presence of liquid water.


Description of the technology

Technology Features & Specifications

CHA framework (3D pore structure), 4 Å opening, > 400 m2/g surface area, H-form, LOI 1000 °C < 35% wt.

Potential Applications 

Where molecular sieves are used for emission control (industrial VOC removal, off-gas purification, green house gas control), as industrial process catalysts or for adsorption (odor removal, heat management). Such applications include:

- Heat management (served market)

- Automotive emission control (served market)

- Adsorption (active carbon replacement)

- Production of petrochemical intermediates

- Processing of chemicals and fine-chemicals

About Clariant

Large Enterprise from Switzerland

Clariant is a globally leading specialty chemical company and stands out for above-average value creation for all stakeholders. We develop sustainable and innovative solutions for many industries. Our portfolio is designed to meet very specific needs with as much precision as possible. At the same time, our research and development is focused on addressing the key trends of our time. These include energy efficiency, renewable raw materials, emission-free mobility, and conserving finite resources. For Clariant, sustainability is a prerequisite to entrepreneurial thinking. Development, innovation, procurement, manufacturing and customer benefits – there are starting points for more sustainable business everywhere.

Clariant is active in three key focus Business Areas: Care Chemicals, Catalysis, and Natural Resources. We have a broad geographical footprint with close to 50% of sales coming from emerging markets. The majority of the end-markets have inherent growth drivers.

– Care Chemicals comprises Industrial & Consumer Specialties and New Business Development activities as well as the future industrial biotechnology business. It follows lifestyle-driven megatrends. Innovative developments like sugar-based surfactants for personal care as well as biofuel made from agricultural residues or crop protection adjuvants produced from renewable oils rank high in their respective market segments and strengthen our position as a supplier of sustainable products.

– Catalysis develops, manufactures and sells a wide range of catalysts for the petrochemicals, plastics and refining industries. Its main business drivers are improving chemical process efficiency, enabling the use of alternative feedstocks (natural gas, coal and biomass) and developing environmentally compatible catalytic solutions which e.g. reduce harmful greenhouse gases.

– Natural Resources, consisting of the businesses Oil & Mining Services and Functional Minerals, is characterized by high growth, low cyclicality and a strong orientation towards promising industry trends. From bentonite for oil refining to natural molding sand additives with Low Emission technology, we create special chemicals which help to keep the global economic engine fueled.

In order to leverage synergies across all Business Areas and create greater transparency, Clariant’s research and development is based on four technology platforms: Chemistry & Materials, Biotechnology, Process Technology, and Catalysis. Here, the forward-looking chemical technologies are combined with custom-made and sustainable solutions, using holistic and innovative process development.
