Catalysis for Chemical Production Applications

CATALYSTS. . . for chemical production

The complex structure of natural montmorillonite results in many interesting properties making it applicable in a range of industries (see parent company and other divisions). Catalysis is an example of a  specialised industry in which montmorillonite is well known.

Mg2+/Al3+/Fe2+ substitution in the clay layers gives rise to interlayer cations which  neutralise the clay charge. These weakly bound cations of Ca2+, Na+  and Mg2+ have Lewis acid properties. The cations absorb water, widening the pore size of the clay resulting in a source of Brønsted acidity due to  polarisation of the hydration sphere. Other acid/basic sites exist at the edges and on the surface of the clay layers giving rise to interesting catalytic properties.

We have the capability to modify the particle size and the nature and concentration of the active sites. Alternatively, a thoroughly-defined bentonite deposit can be carefully mined, processed and  utilised in certain applications with no chemical additions to the clay – a truly natural catalyst!




Natural Bentonite:

We have several bentonite mines distributed globally which have been fully chemically characterised by our scientists providing us with information on consistency and longevity of supply. Our natural processed Ca-bentonites are used in particular oleochemical reactions.

Acid Activated Bentonite:
An acid treatment of natural bentonite results in a modification of the structure and an increase in the Brønsted acidity. This environmentally friendly material acts as a solid acid catalyst or exploitation of its absorption properties make it essential as a bleaching earth in the oleochemical industry.

Ion-Exchanged Bentonite:
Our capabilities allow us to modify, refine and purify a carefully mined natural bentonite. This is a precise process of ion-exchanging the inter-layer cations with protons or other alkali/transition metals. This process affects the active sites of the montmorillonite and hence the catalytic activity.

We understand the needs of each customer are unique and invite you to contact us for further information on our products and services.
