Effects Of The Inclusion Of Rice Hull Derived Bio-Oil On Wood Pellet Production, Tyler E. Lowe Dec 2021

Effects Of The Inclusion Of Rice Hull Derived Bio-Oil On Wood Pellet Production, Tyler E. Lowe

Theses and Dissertations

Wood pellet production has become an advancing industry for the sake of reducing greenhouse emissions into the atmosphere especially, in European Union countries. Researchers and industry executives seek new methods and materials to improve the pelletization process. Rice hulls or husks has the potential to aid in wood pelletization as they possess high calorific values. This study focuses on using rice hull derived bio-oil from pyrolysis, which will also decrease ash content, as an additive to aid in the wood pelletization process. Using two groups of rice hull derived bio-oil as an additive in wood pelletization: Group 1 uses heavy …


Laboratory Evaluation Of The Impact Of Additives On Asphalt Binders Used In Cold Regions, Neirouz Bouhrira Aug 2020

Laboratory Evaluation Of The Impact Of Additives On Asphalt Binders Used In Cold Regions, Neirouz Bouhrira

Theses and Dissertations

The objective of this research study is to evaluate the effect of additives (polymers, nanomaterials, and softening agents) on rutting, cracking, and fatigue performance of asphalt binders commonly used in cold regions (PG 52-34 and PG 64E-40). In this study, the first phase consisted of using polymers (Styrene-Butadiene-Styrene, Ground-Tire-Rubber) and nanomaterials (TiO2 and SiO2) to modify two asphalt binders used in cold regions (PG52-34 and PG64E-40). The second phase of the study consisted of adding a combination of softening agents (Corn oil or Sylvaroad) with polymers (SBR, Epoxy, and SBS) to PG52-34 asphalt binder. The performance evaluation was conducted using …
