So2-Alcohol-Water Fractionation Of Sugarcane Straw, Asif Sharazi

Electronic Theses and Dissertations

Climate change resulting from fossil fuels combustion is motivating researchers to explore feasible routes to convert renewable biomass into biofuels and biochemicals for a sustainable society. Typically, biofuel is produced from corn or sugarcane but both feedstocks compete with human food supply. Thus, lignocellulosics as renewable feedstock represent a more ethical and ecofriendly approach. Sugarcane straw (SCS) is a cheap and abundantly available feedstock which potentially can be used for biofuels/biochemicals production. It can also help to mitigate environmental and health problems resulting from conventional practice of SCS burning in the fields.

There are different biomass conversion technologies for production …

Simulating Microbial Electrolysis For Renewable Hydrogen Production Integrated With Separation In Biorefinery, Christian James Wilson

Masters Theses

Biomass conversion to hydrocarbon fuels requires significant amounts of hydrogen. Fossil resources typically supply hydrogen via steam reforming. A new technology called microbial electrolysis cells (MECs) has emerged which can generate hydrogen from organic sources and biomass. The thermochemical route to fuels via pyrolysis generates bio-oil aqueous phase (BOAP) which can be used to make hydrogen. A process engineering and economic analysis of this technology was conducted for application in biorefineries of the future. Steam methane reforming, bio-oil separation and microbial electrolysis unit operations were simulated in Aspen Plus to derive the mass and energy balance for conversion of biomass. …

Towards A Cost-Effective Biorefinery : Production Of Activated Carbons From Residual Biomass For Energy Storage Devices., Zachary Dean Herde

Electronic Theses and Dissertations

Biomass processing for industrial products and biofuels has gained an increasing presence as society looks to using sustainable resources for manufacturing and renewable fuels for energy. However, these sustainably produced materials and products cannot gain a competitive edge because of the manufacturing expenses that are a result of high process temperatures and pressures. In order to lower these costs, theoretical modeling has described a value-added co-product strategy as one of the best ways to combat high bioprocessing prices. Biomass has been shown to make effective carbons for energy storage devices such as supercapacitors and batteries. These carbons, with the right …
