When using bentonite as a binder, the technical catalyst showed a decreased biooil deoxygenation activity, which was assigned to the loss of most of ZSM5 acidity by ionexchange with Na + cations from the clay. In bentonite besides Na, there are other cations such as Fe, Mg, K, and Ca, the presence of which can inhibit catalytic activity.

Industrial Applications of Bentonite SpringerLink. Bentonite is employed by industry to perform a multitude of jobs. Certain industrial applications become apparent from an understanding of the composition and structure of bentonite, and the properties they create.
INDUSTRIAL APPLICATIONS OF BENTONITE 275 is an aluminum octedral sheet (Fig. 3). Lengths and widths of montmorillo nite flakes are from 10 to 100 times the thicknesses. The montmorillonite lattice is negative in charge, owing primarily to isomorphous replacements of ions within the structure. ...
Bentonite magma is used as a thickening agent in paints, dyes and polishes. Bentonite, when exposed to liquid, thickens and forms a gel or paste, according to the Industrial Minerals Association of North America. This same thickening ability makes it an effective lubricant in diaphragm walls, foundations, and in tunneling and drilling operations.
Bentonite has high swelling properties along with good viscosity and liquid limit. These properties are highly valued in most of the industrial applications. Sodium bentonite is well suited as a binder in the preparation of pellets, and in foundry and oil well drilling mud. Bentonite also acts as a suspending agent in oil well drilling fluids.
Bentonite binders enable economic and environmentally friendly foundry operations since the majority of the sand and binder is reused in a cyclic system. Prerequisite is a suitable bentonite with a stable thermal durability, and at the same time providing efficient shakeout behaviour.
The process steps "cooling", "preparation" and "mixing" are performed in one mixing unit within the core period of 70 seconds, which is fixed by physical and technical constraints. Within this period – the sand is cooled to exactly 40°C, – bentonite with a residual moisture content of .
