- Quick - scan estimating model of Higher Heating Value of oil palm empty fruit bunches based on ash from proximate analysis data J . M. Villegas H . Avila Ingeniería Biofuel energy Proximate analysis Higher Heating Value Lignocellulosic Biomass Oil Palm Empty Fruit Bunch (EFB) A correlation model developed for the quick - scan estimation of th e Higher Heating Value (HHV) based on the ash content from a proximate analysis of Oil Palm Empty Fruit Bunches (EFB) is presented in this paper. The correlation was developed using a be st subsets regression method with data of biomass samples. EFB were ta ken directly from the end of the processing line (the process exit after the fruit removal section) in agro - industrial palm oil extraction facilities that are located on the Colombian coast. The correlation is also compared with other published correlation s of lignocellulosic biomass. After conducting a statistical analysis from proximate analysis variables expressed in the dry basis for Fixed Carbon (FC), Ash content (Ash), and Volatile Matter (VM), colinearity was iden tified be- tween Ash - VM - FC, VM – FC , in developed models that show unsatisfactory behavior when these variables are included, indicating that these models are inadequate. Finally, the correlation model for a quick - scan estimation on the dry basis was obtained based on the Ash content from a proximate analysis of EFB (HHV= 0.827Ash + C, with C between 9.97 and 12.4), with a mean absolute error (MEA) lower than 3% and a marginal mean bias error (MBE) of 0.19%, and R 2 = 0.8, indicating that the model has an HHV with single input variable predictive capability. This model can be used as a support tool for quick - scan estimation when evaluating the available bioenergy in the processing of EFB using economical and efficien t energetic indicators. The minimum and maximum values of HHV obtained for EFB were 13.6 and 21.91 MJ/kg, respectively . 2014 artículo científico 0120-5609 https://www.redalyc.org/articulo.oa?id=64331837007 en http://www.redalyc.org/revista.oa?id=643 Ingeniería e Investigación application/pdf Universidad Nacional de Colombia Ingeniería e Investigación (Colombia) Num.2 Vol.34
