High density solid biofuel from oil palm biomass. Large quantities of oil palm biomass available can significantly become the important source for renewable energy in Malaysia in the form of pellet or briquette. Nonetheless, lignocellulosic biomass should be treated to increase their energy efficiency prior to the combustion. Therefore, the aim of this study was to investigate the effects of torrefaction treatment on the weight loss and energy properties of oil palm biomass (oil palm trunk and empty fruit bunch). The lignocellulosic biomass was torrefied at three different temperatures (200 to 300 °C) within 15 to 45 min. Response surface methodology (RSM) was used for optimization of torrefaction conditions, to determine the maximum energy properties and minimum weight loss. Results showed that heating values of biomass was affected by treatment severity (cumulated effect of temperature and time). While the reaction temperature had a strong impact on the energy density of torrefied biomass, the effect of treatment time was considerably lesser under the torrefaction conditions used in this study. It was demonstrated that each biomass type had its own unique set of operating conditions to achieve the same product quality. The optimized torrefaction conditions were verified empirically and applicability of the model was confirmed. The results of this study could be used as a guide for the production of high density solid biofuel from oil palm biomass. Conclusively, high density solid biofuel from oil palm biomass can be produced using torrection method.

Stałe biopaliwo z biomasy palmy oleistej. Duże ilości biomasy palmy oleistej dostępne na terenie Malezji mogą pełnić rolę odnawialnego surowca energetycznego (np. w postaci peletów lub brykietów). Odpowiednie przygotowanie tego paliwa przed spalaniem pozwala zwiększyć jego wydajność energetyczną. Przeprowadzone badania miały na celu określenie wpływu toryfikacji na utratę masy i właściwości energetyczne biomasy pochodzącej z pnia palmy oleistej oraz z gniazda nasiennego. Przyjęto następujące warunki toryfikacji: temperature od 200 do 300 °C, czas 15 - 45 minut. Optymalizację warunków toryfikacji przeprowadzono metodą RSM. Uzyskane rezultaty pokazują silny wpływ temperatury procesu na kaloryczność paliwa. Wykazano, że każdy typ surowca – dla maksymalnej wydajności energetycznej – wymaga oddzielnej optymalizacji warunków toryfikacji. Empirycznie potwierdzono poprawność przyjętych modeli matematycznych i dowiedziono użyteczności biomasy z palmy oleistej jako surowca energetycznego.
