TPR (Temperature-Programmed Reaction) set-up:

Application: to study interaction between solids and gas flow (one reactant gas component in the flow) at atmospheric pressure under isothermal conditions or under desired temperature profile. The gas consumption/release is determined via the difference in thermal conductivity between feed flow and effluent flow. Temperature interval 25 – 1100 °C, gas flow 20 – 150 ml/min, amount of the solid required for one experiment 100-300 mg

Information obtained:

temperature interval in which reaction occurs;

amount of gas reacted/consumed/released

Application examples:

reduction by H2, CO;

oxidation by O2;

gas consumption/release (CO2 adsorptive removal/sorbent regeneration)
