APPLICATION NOTES
CHARACTERIZATION OF MICROPOROUS MATERIALS By Carlos A. Leon y Leon D.
All solid powders, and in particular those with apparent surface areas > 400 m2/g, are bound to contain micropores. The importance of micropores li...
MEASURING ACIDITY IN ZEOLITES USING TPD
Temperature-programmed desorption (TPD) of basic molecules from the surface of zeolites has been extensively used to measure their acid properties. Th...
EFFECT OF SOME EXPERIMENTAL PARAMETERS ON TPR PROFILES
Temperature-programmed reduction (TPR) techniques can yield direct information on the reducibility of catalysts and catalyst precursors and is an exce...
INTRODUCTION TO SLURRY REACTORS
Many industrial processes involve multi-phase systems, and perhaps the most complex is the gas-liquid-solid or slurry reactor. The complexity of this...
LABORATORY AND COMMERCIAL-SCALE CATALYTIC REACTORS
Designing and using laboratory-scale reactors for studying catalysts can be a very confusing process. Laboratory catalytic reactors are used for a var...
STEADY-STATE ISOTOPIC TRANSIENT KINETIC ANALYSIS (SSITKA
In the study of reactions on heterogeneous catalysts over the past 40 years, much use has been made of transient kinetic techniques in order to provid...
INTRODUCTION TO THE DESCRIPTIVE EQUATIONS FOR CHEMICAL REACTORS
There are 3 fundamental ideal types of reactors. Laboratory reactors are almost exclusively related to these ideal forms. Larger reactors, ...
METAL CRYSTALLITE SIZE DETERMINATION: COMPARISON OF CHEMICAL AND PHYSICAL METHODS
Recent Altamira Notes have discussed the use of several different chemisorption techniques to determine crystallite sizes for supported metal catalyst...
PULSE CHEMISORPTION
Previous issues of Altamira Notes have discussed different selective chemisorption techniques and how they may be used to determine the specific metal...
VOLUMETRIC CHEMISORPTION METHODS FOR METAL CRYSTALLITE SIZE DETERMINATION
One of the most important properties which characterizes a supported metal catalyst is its specific metal surface area. This information may be gained...
TEMPERATURE-PROGRAMMED DESORPTION OF ADSORBED SPECIES FROM CATALYST SURFACES
Temperature-programmed desorption (TPD) of species adsorbed on the surfaces of metal oxides or supported metal catalysts is a technique commonly appli...
Chemisorption and Catalysis on Supported Metals
Chemisorption, the chemical bonding between gas-phase molecules and surface atoms, is the first and most important step in a catalytic reaction On sup...
