The Effect Of Process Variables On Pyrolysis In A Freefall Reactor, Preston Gable Jan 2014

The Effect Of Process Variables On Pyrolysis In A Freefall Reactor, Preston Gable

Graduate Theses and Dissertations

The focus of this work is to test variables of fast pyrolysis conditions in a free fall reactor in order to better understand their impact on pyrolysis products, specifically optimization of bio-oil yields. In the first study, a design of experiments was performed and products were analyzed to evaluate the effects of temperature, sweep gas flow rates, and particle heating time, on bio-oil yields. This study proved particle heating time to be a very important variable effecting bio-oil yields, and that a heating time of greater than the traditionally assumed two seconds must be achieved in order to optimize yields ...


Development Of A Co-Firing Fuel From Biomass-Derived Binder And Crushed Coal, Andrew Friend Jan 2013

Development Of A Co-Firing Fuel From Biomass-Derived Binder And Crushed Coal, Andrew Friend

Graduate Theses and Dissertations

The focus of this work was the development of a co-firing boiler fuel for use in the coal power plant industry. This fuel, known as co-fire pellets, is a densified product comprised of crushed coal and a renewable binder derived from the liquid product of the fast pyrolysis of lignocellulosic biomass. The co-fire pellets can help meet certain state and federal regulations related to electricity production. A central composite design of experiments was used to evaluate properties of the co-fire pellets based on four factors relating to the makeup of the pellets. These factors are coal particle size, coal moisture ...
