Summary:

A dual-screw feeder was designed for desulfurization of coal. This reactor contains two screw tubes, the inner tube acting as a coal pyrolizer and the outer tube acting as a desulfurizer with hot calcined lime pellets or other renewable sorbent pellets. The objectives of this project is to study the feasibility of an advanced concept of desulfurization and possibly some denitrification in this coal feeder. In this year, two basic studies have been performed: (1) the desulfurization and (2) the denitrification due to mild pyrolysis. Specifically, the following tasks have been performed: (1) Setting up the Dual-Screw reactor, (2) Determination of the pyrolysis product and the sulfur distribution in char, tar and gas based on experimental data, (3) Study of the devolatilization, the desulfurization kinetics and the denitrification kinetics and obtaining the basic kinetic parameters, (4) Study of the sulfur removal efficiency of lime pellets fed into the outer tube of the dual-feeder reactor, (5) Study of the effect of the coal particle size on pyrolysis and desulfurization, (6) Study of the coal pyrolysis and desulfurization using a TGA(Thermal Gravimetric Analyzer).
