Drive Yield and Optimize Process Conditions in Catalyst Development

As the world’s leading supplier of high-performance material characterization technologies, Micromeritics helps scientists in catalyst development and screening save time and resources. We have extensive experience of building bespoke catalyst screening units for industrial and academic customers, from tailored analytical units through to complete pilot plants.

Around the world, catalysts enable and speed up chemical processes that facilitate materials that sustain successful economies and societies. Catalysis drives conceptual and technical innovation which opens unused potentials for achieving clean water, clean energy, and sustainable food supplies.

Catalyst development focuses on improving existing processes by increasing the yield and selectivity, along with energy savings in production processes. In addition, new catalysts will help develop new methods to use raw materials that cannot yet be utilized or to treat recyclable wastes. Understanding porosity and surface properties, the physical structure of a catalyst or composition options, will lead to better performance and resolved failures.

Micromeritics Catalysis Instruments

AutoChem III

The AutoChem from Micromeritics is the most widely used and highly cited system for catalyst reactivity characterization because it is also the most automated, highly accurate system for chemisorption and temperature-programmed reactions.

The all new AutoChem III meets and exceeds that performance with a design that will save you hours a day, make the most sensitive, reproducible measurement, and enhance operator safety.

AutoChem II HP

Complex characterizations are made easy by the Autochem II HP specifically designed to run experiments starting from atmospheric pressure up to 1000 psia (6.9 MPa), investigating the behavior of catalysts in conditions similar to real manufacturing plants. The standard detector is a high precision, high sensitivity, high linearity, and corrosion resistant TCD that can be integrated and coupled with an external detector like a mass spectrometer for selective gas monitoring. Signals are easily synchronized by the MicroActive control software.
