Biogas Upgrading Via Solid Resin-Based Amine Sorbents, Olusola Johnson
USF Tampa Graduate Theses and Dissertations
Biogas is a valuable renewable energy generated from anaerobic digestion of biodegradable organic matter. It is applicable as fuel in vehicles, for the generation of electricity, industrial heating, or as raw material to produce chemicals, liquid fuels, syngas, and compressed natural gas (CNG). Carbon dioxide (CO2) and methane (CH4) are the major components in biogas, with a trace amount of contaminants, including hydrogen sulfide (H2S), water vapor (H2O), nitrogen (N2), ammonia (NH3), oxygen (O2), carbon monoxide (CO), halides, volatile organic compounds (VOCs), siloxanes, and hydrocarbons.
The source of biogas, which is anaerobic digestion of different organic matter or landfill decomposition, …
Low-Grade Kaolin Clay Natural Resource For Use As A Supplementary Cementitious Material In Structural Concrete Elements, Brandon X. Lorentz
Low-Grade Kaolin Clay Natural Resource For Use As A Supplementary Cementitious Material In Structural Concrete Elements, Brandon X. Lorentz
USF Tampa Graduate Theses and Dissertations
At the turn of the century, low-grade kaolin clay (LGK) was presented as a widely available and potential natural resource of supplementary cementitious materials (SCM) for producing high performance concretes. In using LGK as an SCM, clinker production is reduced, aiding environmental concerns with associated CO2 emissions. These types of clays have very heterogeneous mineralogy and microstructural characteristics, causing unique influences on concrete structural and flow performance, although these influences are not well understood. This research studies LGK natural to the state of Florida and assesses their potential use as high performance SCM.
Ten kaolin clays were obtained through a …
