Resumo: Brazilian coking coal (Barro Branco seam) were used to produced several binary coal blendswith traditional coking coals. The plastic properties of such blends were study by Gieselerplastometry in order to identify possible interactions between coals. The magnitude ofthe interactions was estimated by the comparison of measured and predicted values ofmaximum fluidity and the temperatures that define the plastic range. Brazilian coal is char-acterized by an anomalous ultra-high fluidity and is an interesting plasticizing agent forcoal blends. The results also revealed that the Brazilian coal has a positive synergy in termsof plasticity with other coking coals. This synergy results in blends with higher maximumfluidity and initial softening temperatures than expected by additivity. However, such inter-action did not change the maximum fluidity and the resolidification temperatures. Positiveinteractions were linked to the transfer of a certain amount of liquid or volatile plasticizing material from Brazilian coal to other coals.
