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. Keywords: Pyrolysis, sawdust mahogany, heating rate, temperature, mass,low heating value

Abstract

Pirolysis is thermochemical decomposition process of biomass into useful product. A method that can be used is a rotary kiln pirolyzer which consist a heating cylinder that rotate with a certain rotation speed. This research is aimed to get the effet of temperature due to char product quantity of switenia macrophylla rotary kiln pirolysis.The research is done by pirolysis experiment with 200 gram of switenia macrophylla in dust form. Temperature heating is varied 250 C, 350 C, 450 C, 500 C, dan 600 C. The heating temperature is provide by eletric heater with control system. Temperatur is measured with K type thermocouple. The heating process is taken for 180 minutes using stopwatch. The measurement is done for biomass and char volume using measuring cup. Mass is measured using scale. Low heating value is measured using bomb calorimeter.The result show that temperatur has effect due to char product of switenia macrophylla rotary kiln pirolysis. Char mass loss tend to increase due to temperature increasing. Low heating value and char porosity tend to increase due to mass loss percentage increasing. Shrinking factor and percentage of yield energy tend to decrease due to mass loss percentage increasing. Keywords: pirolysis, rotary kiln, char, temperature
