The invention of the first zeolite catalyst in the 1960’s for use in gasoline manufacturing revolutionized the process and continues to do so as more efficient catalysts are developed today. As the origin of the name ZeoNet, a contraction of “zeolite” and “network” refers to this significant event in the history of industrial and chemical engineering. Our network of experts serves as a catalyst for transformation. The image shown here represents the remarkable molecular structure of zeolite.

This 3D reciprocal lattice of a zeolite catalyst was reconstructed from 1450 electron diffraction frames collected by Rotation Electron Diffraction (RED). More than 8000 reflections were collected. The structure could be solved from the RED data.


ZeoNet manages projects from end-to-end, but could begin engagement at various stages of projects between initiation, implementation or support. We offer assistance ranging from multi-disciplinary teams, to smaller teams of consultants, depending on project requirements.


ZeoNet operates globally, and is headquartered in Houston, Texas at One Riverway, Suite 1700.
