3P Instruments AMI-300HP high pressure catalyst characterization instrument
The AMI-300HP is an automated high pressure catalyst characterization system. The AMI-300HP performs dynamic high pressure temperature-programmed experiments designed to reach 100 barg (higher pressures available in custom instruments). When integrated with a pump, the AMI-300RHP provides the most sophisticated and automated characterization and micro-reactor instrument in the industry.

Chemisorption experiments on Pt based catalysts by 3P Altamira
This application is an example of a Pt catalyst characterization by a pulsed experiment. The results, like a TPD, will tell us uptake, dispersion, surface area and crystallite size.

Chemisorption experiments on Ni based catalysts by 3P Altamira
This application is an example of common catalyst characterization experiment that will tell us surface area, dispersion, activation energies and basic desorption temperature profiles for a nickel based catalyst.

Chemisorption experiments on Co based catalysts by 3P Altamira
This application is an example of common catalyst characterization experiment using a temperature-programmed reduction (TPR) technique that can yield direct information on the reducibility of a catalyst and catalyst precursors. As such, it is an excellent technique for characterizing a variety of catalysts.

Acid site determination on a zeolite catalyst by 3P Altamira
To help evaluate the applicability of a particular catalyst, Temperature Programmed Desorptions (TPD’s) are commonly performed. TPD’s of basic molecules from the surface of zeolites have been extensively used to measure their acid properties.

Breakthrough curves of polar and nonpolar vapors on activated carbon
In this application, the breakthrough curves of water and toluene from nitrogen were measured and evaluated. It was shown that for toluene a typical S-shaped breakthrough with well defined temperature peaks was obtained, whereas the shape for the breakthrough and for the temperature profile of water is highly dependent on the water concentration.

The use of mixture and pure gas adsorption isotherms for further calculations and predictions using 3P mixSorb
3P Instruments offers two general ways to obtain information about mixed gas adsorption processes; first with the measurement of the dynamic sorption process with the mixSorb L by 3P Instruments and second by use of the 3P sim software of the mixSorb L to calculate mixed gas data using pure gas isotherms.

Super-ambient pressure gas separation studies using 3P mixSorb coupled with mass spectrometer
The 3P Instruments mixSorb L coupled with a mass spectrometer offers the ability to study the adsorption behavior of the components of ternary gas mixtures and can be used as an experimental tool to optimize porous materials for specific gas separation applications. Such valuable performance characteristics can only be derived from dynamic experiments.

Breakthrough curves on carbon molecular sieves – experiment and modeling using 3P mixSorb
The dynamic method for the measurement of gas adsorption breakthrough curves is necessary to estimate kinetically controlled sorption processes which cannot be predicted by thermodynamic simulation. The 3P Instruments mixSorb L can be used for such practical investigations to obtain relevant data for kinetically controlled pure and mixed gas sorption dependent on temperature, pressure and gas flow.

Determination of breakthrough curves and effective gas sorption capacities
Fully automatic gas sorption analyzer, the mixSorb L, from 3P Instruments is a sophisticated analyzer that effectively closes the knowledge gap between equilibrium BET and pore size measurements of porous materials and the dynamic determination of their effective sorption capacities.
