A review of recent laboratory research and commercial developments in fast pyrolysis and upgrading

“…Tables Table 1 Overview of Fast Pyrolysis Developments.

“…A fluidised bed reactor with a cyclone and hot filtration system yielded bio-oil with low solids (<0.005 wt%) and metal contents [111][112][113][114]. Hot gas filters can be positioned inside [94,108] or outside the fluidised bed reactor [111][112][113][114].…”

Direct conversion of biomass to bio-petroleum at low temperature

“…Among the thermochemical processes [6], pyrolysis has received increasing attention [8]. A large number of research projects in the field of biomass pyrolysis have been performed [9][10][11][12][13][14][15][16][17][18][19][20][21][22][23] to obtain high quality liquid oil. The oxygen content in the rice straw bio-oil obtained through steam and static pyrolysis is in the range of 19.89-25.70 with heating value 28.52-25.58 MJ/kg [12].…”

Effect of filter media size, mass flow rate and filtration stage number in a moving-bed granular filter on the yield and properties of bio-oil from fast pyrolysis of biomass

“…They were used with fluidised bed reactors applying radiate pine (Kang et al, 2006;Park et al, 2008), rice straw (Lee et al, 2005), bamboo sawdust (Jung et al, 2008) and oriental white oak (Park et al, 2009) as feedstocks. The candle filter was found to efficiently reduce the solids and alkali contents of bio-oil to below 0.1 wt.% and 4.1 ppm, respectively.…”
