Energy Densification Via Hydrothermal Carbonization, Keri Noack
Festival of Communities: UG Symposium (Posters)
A process called hydrothermal carbonization (HTC), also known as wet torrefaction involves treatment of raw biomass in hot, pressurized water. HTC of woody biomass has been shown to significantly increase the energy density of the feedstock, producing a biochar, similar to coal, having up to 40% higher calorific energy content. Feedstocks investigated include Tahoe chips, Pinion/Juniper chips, Rice hulls, and Corn Stover pellets pre-treated at 215 °C, 255 °C, and 295 °C. Chemical analyses were conducted on the gaseous, aqueous, and solid HTC products. Energy contents of the solid biochar products were measured by calorimetry, and mass balances were determined.
Spectroscopic (Ir, Nmr, Uv-Vis), Theoretical Study And Optical Properties Of 9,10-Dihydrobenzo(A)Pyrene-7(8h)-One And 7, 8, 9, 10-Tetrahydrobenzo(A)Pyrene, Mireya Martinez
Undergraduate Research Conference
Polycyclic aromatic hydrocarbons (PAHs) are organic molecules found in the environment. The PAHs are formed from incomplete combustion, are found in diesel exhaust particles, grilled foods, gas burners, emission from wood, and cigarette smoke. These compounds are known to be carcinogenic and mutagenic1,2. Spectroscopic studies were performed on two PAHs, 9,10- dihydrobenzo(a) pyrene-7(8H)-one and 7,8,9,10- tetrahydrobenzo(a)pyrene, which helped to characterize them. Also, a theoretical infrared study was done on 9,10-H2BaP, a scaling factor was found for a simulated infrared spectrum.
