In the Philippines, the government has started to impose environmental regulations to keep its environment free from hazardous and toxic elements. Among the detrimental pollutants being looked into, the government is focusing its attention to the hazardous emissions from coal-fired thermal power plants, in particular, to the reduction of SO sub x emissions. ITDIA had developed a process for the production of highly active absorbents for SO sub x removal using coal ash and limestone, raw or calcined, as its principal raw materials. In previous studies, the chemical composition, mineral composition, morphological structure and thermal history of coal ash samples were determined to find out their effects on the preparation of the absorbents for SO sub x removal. Studies on the production of SO sub x absorbents were conducted and the performance of these absorbents were measured. In this particular paper, the effect of sieving the coal ash samples to obtain most reactive materials will be investigated
