A mini directly-heated reactor (mini-DHR) was constructed to measure the gasification rate of coal char handily under high temperature (〜1200℃) and high pressure (〜2 MPa) in the presence of CO_2, CO, H_2 and H_2O. The mini-DHR was made of U-shaped SUS or Pt tubing of 3 mm I.D. The reactor itself was used as a heating element. An electric current of 75-150 A and a few volts were introduced to the reactor to heat up the reactor up to 900 to 1200℃. About 1 mg of char placed in a platinum mesh basket of 1.0 mm I.D. and 10 mm high was gasified under various conditions to obtain the char conversion, X, vs time relationships. Systematic measurements of gasification rates were performed in the mixture of CO_2 and CO, and a gasification rate equation was established for an Australian brown coal.
