AGUIAR TRUJILLO, Leonardo et al. FAST PYROLYSIS PROCESS OF ORANGE SOLID WASTE. FACTORS INFLUENCE IN THE PROCESS. cen. az. [online]. 2015, vol.42, n.2, pp. 39-47. ISSN 2223-4861.

The orange processing industry generates high volumes of solid residue. This residue has been used in animal feeding and biochemical processes. A possible energy use of the waste can be thermochemical fast pyrolysis process. The objective was to determine the influence of the heating rate and temperature in the process of rapid pyrolysis of orange solid residue. In the process a design, 2^k full factorial experiment was used, evaluating the influence of the independent variables and its interactions on the answers, using a 95 % significance level.We found that temperature is the most significant influence on the responses parameter having significant influence on the yields to: gas, coal, tar and the calorific value of the gas and the heating rate does not influence the answers. Finally, the interaction affects the gas yield.The results obtained in this study are: Rgas (19 - 38) %, Rchar (25 - 42) %, Ralq (6 - 12) %, PCIgas entre (140 - 1050) kJ/m³N.
