Rotating Heater Pyrolyzer (Rhp): A New Pyrolysis Technology For Biochar Production, Ariel Porat

Electronic Thesis and Dissertation Repository

Biochar provides an effective and inexpensive carbon sequestration technology to combat climate change. It is formed through a process known as pyrolysis; where biomass is thermally decomposed in the absence of oxygen. In this study, a new pyrolysis reactor called the Rotating Heater Pyrolyzer (RHP) was designed and built for biochar production. RHP derived biochar properties were compared to biochars produced with a standard batch pyrolysis reactor (Pyrolytic Shaker Reactor (PSR)) to determine RHP performance. Using several biochar characterization techniques, the soil amendment potential of two solid anaerobic digestate feedstocks were investigated. Woodchip RHP derived biochar processed between 2-3 hrs …

Pyrolysis Of Miscanthus And Products Characterization, Arshdeep Singh

Electronic Thesis and Dissertation Repository

Miscanthus, an invasive crop, has recently gained attention as an emerging energy crop because of certain features such as adaptability to lower temperature, efficient use of water and nutrients, low or no need of nitrogen fertilizers, high biomass yield, fast growing cycle and less intensive agricultural cultivation practices than other energy crops, such as corn.

The literature review is focused on the value-added applications and conversion of Miscanthus for bioenergy and biomaterial applications. The thermochemical conversion technologies reviewed in this chapter include pyrolysis, liquefaction, torrefaction and gasification, whereas biochemical conversion technologies include enzymatic saccharification and fermentation.
