Thermochemical Characterization of Materials using a Novel Laser-Heating Technique



Cary Presser


This article reviews the application of a novel rapid laser-heating technique (referred to as the laser-driven thermal reactor) for characterizing multiphase, multicomponent substances. The technique provides quantitative measurements of various relevant thermochemical properties, including sample heat release rate, chemical kinetics rates, total heat value, specific heat release, and chemical reaction byproduct identification. The technique is currently being used to measure the absorption coefficient of particle-coated filters for atmospheric aerosol research. The optical properties of individual particle-laden droplets are also being studied in the laboratory under tropospheric conditions. In addition, a forensic science investigation of energetic materials is underway to develop a database of their thermal and chemical signatures. Past studies include characterization of simulant hazardous organic wastes and propellants for improving storage safety, and planned future studies are to focus on thermochemical characterization of biomass/biofuels/biodiesel. Results presented demonstrate the capability of this technique to address different thermochemical-related issues associated with a wide variety of applications.
