Upgrading Biomass To Bio-Oil: Catalytic Hydrodeoxygenation And Pyrolysis Of Vanillin And Anisole Biomass Model Compounds, Ahmad J. Yaghi
Upgrading Biomass To Bio-Oil: Catalytic Hydrodeoxygenation And Pyrolysis Of Vanillin And Anisole Biomass Model Compounds, Ahmad J. Yaghi
Theses
The purpose of this project is to investigate capacity of selected formulations of catalysts toward the hydrodeoxygenation (HDO) of biomass model compounds in the gas phase with the underlying aim to produce hydrocarbon cuts that can be directly used as transportation fuels. The first part of this project is to devoted to illustrate procedures for the synthesis of potent (HDO) catalysts. Synthesized catalysts encompass nickel (Ni), cobalt (Co) and palladium (Pd) supported on zeolite, cerium oxide (CeO2) or alumina (Al2O3). Various characterization techniques such as X-ray Diffraction (XRD), Temperature Programmed Reduction (TPR) were deployed …

A Study Of Biochar Production Via Continuous Vacuum-Assisted Pyrolysis, Max Wohlgenant
Graduate Theses & Non-Theses
The present study focuses upon the design, fabrication, and feasibility of the bulk production of scientific biochar for mobile delivery. In the 2022 annual report, the National Academies of Science, Engineering, and Medicine recommended the integration of mobile, decentralized reactors that employ flexible manufacturing and circular economic principles. Biochar production, involving the thermal degradation of biomass under an inert atmosphere to yield remediation media is an ideal material to satisfy this recommendation. Many potential application sites, such as abandoned mines, are remote and limit the construction of large infrastructure. The continuous vacuum-assisted pyrolysis (CVAP) reactor was designed to: increase biochar …
Value Added Products From Nonconventional Agricultural Biomass Waste Through Thermochemical Transformation, Nicolas A. Sarmiento
Value Added Products From Nonconventional Agricultural Biomass Waste Through Thermochemical Transformation, Nicolas A. Sarmiento
Electronic Thesis and Dissertation Repository
The alteration of temperature patterns around the world has become noticeable in the recent decade. Sea level rise, wildfires, and high temperatures have made people realize that climate change is affecting humans more tangibly than ever. Therefore, the United Nations have pushed to make policies to mitigate this problematic situation. This research investigated the production of biochar from agricultural waste through pyrolysis for fighting climate change and adding value to waste. Experiments in a laboratory scale reactor were conducted to obtain yields of pyrolytic products. Then, analysis of products provided data for characterization and the LCA of the tomato plant …
