✦ Synopsis
An apparatus has been designed for kinetic studies of coal devolatilization under closely controlled heating rates, temperatures, and pressures. The reactor system employs a wire-mesh pyrolysis furnace driven by an electronically-controlled power supply to ensure uniform heating rates and precise crossover to a variable length isothermal period; a rapid quenching scheme permits resolution of kinetic processes in 0.1 s intervals, extending the sensitivity of kinetic measurements from the initial stage of pyrolysis through to completion of priman/ devolatilization. Time-resolved kinetic studies on a bituminous coal in vacua (13 Pa) and under helium (0.22 MPa) illustrate the operation of the reactor.
