Slow pyrolysis process (SPP), generally a batch process, is aimed to generate biochar as main product and bio-oil and syngas as by-products. SPP is mainly carried out at moderate temperatures (300 – 700 ⁰C), ramping rate (<1°C s −1) and prolonged residence/holding time (>5 min).Drum reactors, rotary kilns and auger reactors are the commonly used reactors …

The production of pyrolysis gas is mainly dependent on the pyrolysis temperature which also affects the pyrolysis process and quantity of product yields obtained. Increase in the pyrolysis temperature first causes the moisture content present in the biomass to be given off, followed by the devolatilization and decomposition of the biomass.
