摘要: Abstract This paper describes the thermochemical transformation of residual whole olive stones from industrial production pitted and stuffed table olives by using a rotary reactor. experimental investigation chemical, physical fuel properties resulting solids liquids obtained in temperature range between 200 °C 900 °C. Optimum torrefaction conditions, intended to maximize mass energy yields, were at 278 °C resulted solid product with 68 wt% volatile matter, 29 wt% fixed carbon, 58 wt% elemental 0.55 O/C ratio, 23.4 MJ/kg HHV, 11.25 GJ/m 3 apparent density for an yield 89%. The carbonized temperatures 500 °C 900 °C exhibited LHV up 57–66% higher than original biomass. carbonization process generates condensable liquid that represents 50–53 wt% biomass contains 57 61 wt% water 39–43 wt% organic products. carbon content (up 25 wt%) heating value (HHV 5.2 MJ/kg 2.8 MJ/kg, respectively) this is limited. A model has been tested series equations have produced which allow us predict chemical fraction derived process. found linear correlations elemental/proximate composition solids, exponential yields.
