Biomass conversion to produce valueadded products from agricultural and forestry residues Mohammad M. Hossain, Ian M. Scott, Mark Sumarah, Ken Conn, Brian D. McGarvey, Franco Berruti, Cedric Briens 1
Introduction High value products from pyrolysis of biomass Traditional bubbling fluidized bed reactor: Liquid is mixture of many products Better selectivity is required for high value products Use a batch Mechanically Fluidized Reactor (MFR) 2
Reactor Batch Mechanically Fluidized Reactor 3
Stirrer Batch Mechanically Fluidized Reactor 4
Batch Mechanically Fluidized Reactor No need for: Inert fluidization medium (e.g. sand) Fluidization gas Can be used for batch pyrolysis: Liquid cuts can be collected for different temperature ranges 5
Objective Demonstration of batch MFR to obtain model compounds from plant biomass Spent coffee ground Tobacco leaf Caffeine Nicotine 6

Percent yield of caffeine Results: Spent coffee ground Yield of caffeine = g caffeine in temperature cut /g caffeine in biomass 60 50 40 30 20 15 C/min 5 C/min 10 0 Ambient-130 130-180 180-230 230-280 Temperature cut, o C 15 o C/min: 96% recovered Spent coffee ground extract: 5 o C/min: 51% recovered 0.75 mg caffeine/g biomass 8
mg caffeine/g bio-oil Results: Spent coffee ground Purity of caffeine (mg caffeine/g bio-oil) 2.5 2 1.5 1 15 C/min 5 C/min 0.5 0 Ambient-130 130-180 180-230 230-280 Temperature cut, o C 9

Percent yield of nicotine Results: Tobacco leaf Yield of nicotine = g nicotine in temperature cut /g nicotine in biomass 35 30 25 20 15 10 5 0 Ambient-240 240-255 255-270 270-285 285-300 300-500 Temperature cut, o C 15 o C/min: 94% recovery of nicotine 11
g nicotine/g bio-oil Results: Tobacco leaf Purity of nicotine (g nicotine/g bio-oil) for different temperature cuts 0.14 0.12 0.1 0.08 0.06 0.04 0.02 0 Ambient-240 240-255 255-270 270-285 285-300 300-500 Temperature cut, C 12
Conclusions A faster heating rate is better to recover thermally sensitive products such as caffeine The batch MFR can: Recover most of the compound originally in the biomass Provide a liquid with a high concentration of desired product 13
Future work Two dimensional Mechanically Fluidized Reactor (MFR) Combine batch MFR with fractional condensation 14
