The effect of pressure on temperature distribution of albasia sawdust in pyrolysis process

This study aims to determine the effect of pressure on the circulation temperature of compacted sawdust. The biomass used for this research is albasia sawdust obtained from wood processing waste in Yogyakarta, Indonesia. The pressure variations used are 60, 70 and 80 bar. There are 5 sensors placed at a distance of 10 mm each apart from each other. The experimental results show that the greater the pressure, the greater the maximum temperature produced. The largest maximum temperature is obtained at sensor 1, the lowest maximum temperature occurs at sensor 5, this occurs in all pressure variations (60, 70 and 80 bar). The maximum temperature that can be achieved is at a pressure of 80 bar on sensor 1 which is 265 °C, while the lowest maximum temperature occurs at a pressure of 60 bar with a maximum temperature of 80 °C.
