In the last 30 years, there have been major developments in the fast pyrolysis technology, which converts solid biomass to energy-dense, transportable liquid, together with solid co-products(bio-char) and non-condensable hydrocarbon gases. Fast pyroly-sis can produce high liquid yields of up to 75% [3], based on the type of biomass, through rapid thermal decomposition of lignocel-lulosic biomass in the absence of oxygen. However, fast pyrolysis of lignin is not widely investigated because of the difficulties facedduring the continuous feeding and processing of lignin in flu-idized bed reactors. Due to its low melting point (between 150 and 200◦C), lignin is usually found to melt even before entering the reactor, causing blockage of the feeding systems. Other problem encountered during lignin pyrolysis is the slow reactivity, result-ing in the formation of a liquid phase in the reactors leading to thebed agglomeration and subsequent defluidization.
