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.
