The objective of this study was to investigate methods for producing slaked lime with high specific surface. The impact of process parameters and possible additives to be used in the process were studied.Firstly, the effect of ethanol mixed in the slaking water was examined. The ethanolwater mixture had a positive impact on the specific surface area, but sufficiently good results were not reached. Diethylene glycol as additive was tested with satisfying result. The additive enables a considerable increase of the specific surface under several process conditions.Secondly, process parameters to maximize the specific surface area were examined. Initial temperature and particle size of quicklime is effects on the results were studied. Also, the time duration of mixing the quicklime with diethylene glycol and the mixing temperatures’ impact on the results were tested.With an effective additive and optimally adjusted process parameters, high specific surface slaked lime could be produced.
