Aug 15, 2023 · Another important use for zeolites is as catalysts in drug (pharmaceutical) production and in the petrochemical industry, where they're used in catalytic crackers to break large hydrocarbon molecules into gasoline, diesel, kerosene, waxes and all kinds of other byproducts of petroleum.

Zeolites are widely used as catalysts and sorbents. [23][24] In chemistry, zeolites are used as membranes to separate molecules (only molecules of certain sizes and shapes can pass through), and as traps for molecules so they can be analyzed.

Aug 24, 2021 · In this Review, we highlight emerging applications for zeolites and zeolite-based materials in catalysis, separation and host–guest assembly.

Compared with other inorganic materials, zeolites are widely used as catalysts, ion exchangers, and adsorbents because of their adjustable chemical properties, controllable pore structures, and good hydrothermal stability [3, 4].

Sep 21, 2020 · Zeolites can possess both catalytically active Brønsted and Lewis acid sites. There are limits on the distribution of tetrahedral aluminium species: they cannot neighbour each other...

Zeolites are purely inorganic materials and typically produced using hydrothermal synthesis. Major applications for zeolites include refinery catalysts for olefin and fuel production, emissions catalysts for both mobile and stationary applications, petrochemical catalysts for alkylation and isomerization reactions, and specialty catalysts ...

Sep 21, 2020 · Zeolitic catalyst particles are grown with nanosized fins that improve mass transport into the interior of the particle. This delays catalyst deactivation in the methanol-to …

Jun 1, 2000 · Zeolites with eight-membered-ring pores are good catalysts for a limited number of reactions involving small reactant and product molecules. Examples are the manufacture of mono- and dimethylamine from methanol and ammonia or the conversion of …

Zeolites are versatile catalysts not only for large scale petrochemical processes but also in applications related to fine chemicals synthesis, biomass conversion and CO 2 utilization. Introduction of mesopores and heteroatoms opens up additional applications.

Apr 14, 2009 · Zeolites can also play an active role in the quest for raw material change as catalysts providing the required selectivity towards base chemicals. In this contribution, an overview of the current and potential applications of zeolites as catalysts in …
