Slow pyrolysis of imperata cylindrica in a fixed bed reactor

Slow pyrolysis of Imperata Cylindrica has been conducted in a fixed bed reactor to determine the effect of temperature and particle sizes towards the product yield. The characterization of the Imperata Cylindrica has been analysed using several instruments such as Thermogravimetric Analysis (TGA), C...
