Evaporation of primary tar during fossil fuel pyrolysis is one of the processes that can influence yield and composition of pyrolysis products. The objective of this paper was to illustrate the volatility of oil shale primary pyrolysis tars. The focus was on the less volatile heavy end of the tar. T
Different types of forest residual biomass, including pine wood, pine bark and spruce needles, and Estonian Kukersite oil shale, were parallelly subjected to the slow pyrolysis in similar conditions. A Fischer assay, modeling industrial semi-coking retorts, was used. Both the yield and the compositi
