Zusammenfassung:The research aims to investigate the kinetic characteristic of microwave-assisted pyrolysis of palm kernel shells using microwave output power (800, 600, 450, and 300 watts). The research consists of three steps; thermogravimetry analysis, microwave-assisted pyrolysis, and kinetic study analysis. This research showed that increased output power affected the decreasing activated energy, increased heating rate, and accelerated pyrolysis. The findings showed that microwave output power significantly affected kinetic characteristics and the production yield of microwave-assisted pyrolysis. Microwave-assisted pyrolysis ran optimally at 800, 600, and 450 watts but had not yet entirely run at 300 watts. The shells produced high solid products because they had a high lignin content (38.76 wt.%). The shell had a volatile matter content of 67.84 wt. %. Analysis using GC-MS showed that the liquid product contains an aromatic compound which was acetic acid and phenol.
