PERUBAHAN MASSA DAN NILAI KALOR CHAR DENGAN VARIASI HEATING RATE DAN TEMPERATUR PADA PIROLISIS SERBUK KAYU MAHONI (SWITENIA MACROPHYLLA)
Abstract: Product pyrolysis
process is char, tar and gas. Char important parameters are the mass and
caloric value. Therefore, this study discusses the effect of temperature and
heating rate due the mass and low heating value. Variations heating rate used
was 673 K / h and 1073 K / h.Temperature heatingis varied 523 K, 623 K, 723 K,
773 K and 873 K for each heating rate .The heating temperature is provide by
eletric heater with control system (arduino uno system). The measurement is donefor
biomass and char mass using measuring cup and measured using mass scale. Bomb
calorimeter is used to measure teh low heating value Sawdust mahogany dried
powder with temperatures 383-398 K. Sawdust mahogany dry pyrolysis with
variations planned. The heating process pyrolysis is taken for 180 minutes
using stopwatch.The result show that theheating rate and temperatur has effect
due mass char product.The results show that char mass tend to decrease due to
heating rate and temperature increasing.. Low heating value tend to increase
due to heating rate and temperature increasing.
