Abstract
Determination of the particle density is required to address the hydrodynamic study of a moving bed contactor. The measurement of this parameter is complicated when particles are irregularly shaped. In this study, two different techniques were use: compaction by mechanical compression and an alternative proposal, which contemplates the potential of mercury porosimetry for determining the surface and structural properties. It was observed that the results obtained by compacting in all cases are higher than expected. However, the values obtained by mercury porosimetry are more consistent with expected values. For example in the sawdust valued at 500kg/m3, very similar to the value of the original wood (502kg/m3). Values obtained by this procedure adequately represent the relationship between mass and volume of the particle and therefore are valid for hydrodynamic characterization of the biomass.
