Characterization of vegetable biomass coffee husk
Abstract
This work has as main objective to evaluate the physical and chemical properties of different sample size classes of coffee husk as part of the thermal decomposition study of the samples. The granulometric study was conducted using methods: cumulative and differential, as result the average diameter (Dp) was obtained in each case. By the differential method the Dp = 1,29 mm and by the cumulative method the Dp = 1,5 mm, giving a 13,7 % error which is an acceptable value. Applying the experimental methodology the following chemical properties were determined for each particle size: moisture, volatiles, fixed carbon and ashes. For moisture and fixed carbon content there is no definite trend, instead, by decreasing the particle diameter, decreases volatile matter content and ash content increases. Design experiments corresponding to the largest accumulations area was carried out and using the statistical program STATGRAPHICS Centurion XV it was possible to determine the influence of particle size on the properties studied, it was found that this has a significant influence in all cases performed.References
