Book cover Sample Controlled Thermal Analysis

Part of the book series: Hot Topics in Thermal Analysis and Calorimetry ((HTTC,volume 3))

Abstract

Usually catalysts and their precursors are prepared by temperature programmed thermolyses carried out isothermally for a given time at a predetermined temperature, which is reached using a linear heating rate. Under such conditions, uncontrolled temperature and pressure gradients are created in the system and the reaction rates vary significantly during the preparation procedure [1]. Hence, catalysts obtained at the beginning and the end of conventional thermolysis, when the reaction rate is low, are made under very different conditions from those prevailing when the reaction rates are at their highest level. Furthermore, it is well known that rates of many thermal reactions are influenced by the partial pressure of product gases that vary from one instrument to another and lead to irreproducible reaction environments. SCTA techniques can be applied with advantages to avoid these problems and produce catalysts in a reproducible and uniform manner, with pre-determined properties [2].
