Biomass Fast Pyrolysis Using a Novel Microparticle Microreactor Approach: Effect of Particles Size, Biomass Type, and Temperature
Biomass fast pyrolysis is emerging as a front-running approach for the generation of renewable chemical and fuel resources. The pyrolysis temperature, solid and gas phase residence times, and biomass particle size and type have a substantial impact on char, oil and gas yields. A laboratory-scale fast pyrolysis technique was demonstrated using manufactured biomass microspheres. A unique single-particle (~10µg) micro-reactor technology coupled to a millisecond response flame ionization detector (fast-FID) was used to investigate the effects of relevant particle and process parameters and to capture the dynamic of real-time micro-scale single-particle pyrolysis for the first time. The manufactured biomass microspheres were produced by spray drying finely milled microcrystalline cellulose, switchgrass (Panicum virgatum) and tall fescue straw (Festuca arundinacea) flour. Keywords: biomass; fast pyrolysis; single particle; cellulose; switchgrass; tall fescue; flame ionization

An optically accessible pyrolysis microreactor
We report an optically accessible pyrolysis micro-reactor suitable for in situ laser spectroscopic measurements. A radiative heating design allows for completely unobstructed views of the micro-reactor along two axes. The maximum temperature demonstrated here is only 1300 K (as opposed to 1700 K for the usual SiC micro-reactor) because of the melting point of fused silica, but alternative transparent materials will allow for higher temperatures. Laser induced fluorescence measurements on nitric oxide are presented as a proof of principle for spectroscopic characterization of pyrolysis conditions.
