• The objective of this work was to use coal as the raw material to prepare activated coke (AC) catalysts of industrial-scale size for SO2 removal from flue gas and to find the optimal additives and preparation methods. Results showed that activated coke with metal loaded was a suitable method, and that the activated coke catalysts, prepared by loading with CoCl2 or CaCO3 and finally calcining at 700°C, exhibited the best desulfurizing property with a sulfur retention of about 98.6mg-SO2/1g-AC at a reaction temperature of 80°C. Also, the effects of H2O content in the flue gas, reaction temperature and space velocity on the desulfurizing property were investigated to determine optimum operating conditions. An H2O content of about 10% was appropriate for catalysts in this work. In the temperature range 70∼110°C, the catalyst showed good performance for SO2 removal and was gradually deactivated at temperatures above 110°C. Space velocity exhibited an optimal value of 800 h-1. The kinetic behavior varied with space velocity and the desulfurizing property was controlled by adsorption at space velocities below 800 h-1, and controlled by catalytic reaction at space velocities above 800 h-1.
