Abstract

Pyrolytic Conversion of Biomass to Biochar, Biocrude, and ElectricityAbstract –The primary source of alternative energy is the sun. Biomass is the most abundantsolar conversion system besides weather. Pyrolosis of biomass is one of the most promisingtechnologies for energy conversion. This paper describes the efforts of our local university (notnamed) to convert the woody waste stream to useful products. The work includes downdraftgasification, biochar production, agricultural tests with biochar, combined heat and powerscenarios, and the current work of distilling volatilized biomass. The system has six potentialrevenue streams and promises to be the best of the pyrolosis conversion techniques. Biomass,usually chipped wood, is volatilized to release the hydrocarbons as fuel gas and smoke. Thecurrent aspect of this project is the condensation of smoke/wood tar as a means of separationfrom the fuel gas. The six potential revenue products are, waste stream elimination, biocharproduction, biocrude production, heat, carbon sequestration, and fuel gas. The project focus forthis research is small scale application, home, farm, and community. The goal is the creation of aviable method of augmenting building heating while producing useful products from pyrolosis.The work is sponsored by and EPA, P3 student grant. The paper also describes the studentinteraction and the merits of research based teaching.Keywords: gasification, biocrude, syngas, producer gas, pyrolosis, renewable energy, biochar,EPA P3 grant.
