V-CAT is the part of the Porous Heterogeneous Catalysis Center (PHCC), School of Energy Science and Engineering, Vidyasirimedhi Institute of Science and Technology (VISTEC). Our passion is to transfer the scientific knowledge regarding the catalyst design to the potential applications including biomass conversion to produce fine chemicals and materials, petrochemical and refining, waste, and CO2 utilization.
We transferred the innovation from laboratory to pilot plant scale. The main focus of our new catalysts is based on the synthesis of hierarchical zeolites with various functionalities. For example, we have successfully developed several hierarchical zeolite frameworks with different Si/Al ratios. In addition, we can also modify our catalysts with the wide range of catalytic properties, for example, acid-base, and redox properties. Furthermore, to meet the sustainable development, we have developed our catalysts derived from both industrial and agricultural wastes, and it therefore can make the benefits to the environment.
Apart from the design of various hierarchical zeolites, we have also applied our catalysts in the wide range of catalytic processes including bioethanol to ethylene and carbon nanotubes, catalytic cracking of hydrocarbons to light olefins, hydrogenation of unsaturated hydrocarbons, propane dehydrogenation, glucose conversion to hydroxymethylfurfural (HMF) and 2,5-furandicarboxylic acid (FDCA).
Our commitment to quality extends to the people who are interested in an innovation of catalyst development for the novel applications in particular biorefinery. We offer high qualified catalysts (various forms of hierarchical zeolites) in several ways, for example, ion-exchanged hierarchical zeolites, redox-hierarchical zeolites, metal supported hierarchical zeolites for both powder and extruded forms. All of our catalysts have been produced in the high standard laboratory/pilot plant and are available in gram to kg scale with the qualified physical and chemical properties. The characteristics of our catalysts have been verified by means of high standard characterization techniques including X-ray diffraction, scanning electron microscopy (SEM), transmission electron microscopy (TEM), surface area analysis, chemisorption technique, and elemental analysis to ensure you that our catalysts meet with the maximum quality.
V-CAT is not only the supplier but also the research partner assisting our collaborators to develop new types of catalysts for a particular application. We ensure that from our strong research expertise regarding catalysis, our services can deliver the best solutions to customers.

In addition, zeolite can combine with a binder to produce extruded catalysts with cylindrical geometry (pellets) that are ready to use for various catalytic processes. The beneficial aspect of the extruded catalyst is not only to prevent pressure drops in the system but also to inhibit the formation of aggregates. Specifically, customers can request the production of extruded catalysts related to the available powder of our products.
