Development Of A Lab-Scale Auger Reactor For Biomass Fast Pyrolysis And Process Optimization Using Response Surface Methodology, Jared Nathaniel Brown Jan 2009

Development Of A Lab-Scale Auger Reactor For Biomass Fast Pyrolysis And Process Optimization Using Response Surface Methodology, Jared Nathaniel Brown

Graduate Theses and Dissertations

A lab-scale biomass fast pyrolysis system was designed and constructed based on an auger reactor concept. The design features two intermeshing augers that mix biomass with a heated bulk solid material that serves as a heat transfer medium. A literature review, engineering design process, and shake-down testing procedure was included as part of the system development.

A response surface methodology was carried out by performing 30 experiments based on a four factor, five level central composite design to evaluate and optimize the system. The factors investigated were: (1) heat carrier inlet temperature, (2) heat carrier mass feed rate, (3) rotational ...


Design, Optimization And Evaluation Of A Free-Fall Biomass Fast Pyrolysis Reactor And Its Products, Cody James Ellens Jan 2009

Design, Optimization And Evaluation Of A Free-Fall Biomass Fast Pyrolysis Reactor And Its Products, Cody James Ellens

Graduate Theses and Dissertations

The focus of this work is a radiatively heated, free-fall, fast pyrolysis reactor. The reactor was designed and constructed for the production of bio-oil from the fast pyrolysis of biomass. A central composite design of experiments was performed to evaluate the novel reactor by varying four operating conditions: reactor temperature, biomass particle size, carrier gas flow rate and biomass feed rate. Maximum bio-oil yields of 72 wt % were achieved at a heater set point temperature of 600 yC, using particle sizes of 300 micron, carrier gas flow rates of 4 sL/min and Red oak biomass feed rates of 1 ...
