Process Intensification For Rare Earth Elements Adsorption By Resonant Vibratory Mixing, Oluwatosin Adebayo, Richard Ladouceur, Zainab Nasrullah
Graduate Theses & Non-Theses
The adsorption capacity for six rare earth elements (Lanthanum, Terbium, Neodymium, Dysprosium, Praseodymium, and Holmium) by biochar produced from hemp feedstock was investigated. An innovative approach to enhancing the adsorption of rare earth elements using biochar was studied and investigates the potential of resonant vibratory mixing (RVM) as a process intensification method compared to conventional mechanical mixing for the adsorption process. Hemp hurds as source of biomass was pyrolyzed to produce biochar at a temperature of 4500C for 60 minutes. The biochar was characterized by FTIR (Fourier Transform Infra-red), SEM (Scanning Electron Microscopy), Surpass 3 Electrokinetic solid surface analyzer, and …

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 …
Investigation Of The Structure, Chemistry And Functional Performance Of Novel Biochars, Julie Elizabeth Muretta
Investigation Of The Structure, Chemistry And Functional Performance Of Novel Biochars, Julie Elizabeth Muretta
Graduate Theses & Non-Theses
Biochars are a class of carbonaceous materials possessing high degrees of structural and chemical disorder in both organic and inorganic constituent phases. Despite this disorder, and in some cases because of this disorder, biochars have shown strong performance in adsorbing and even sequestering contaminants from soil, surface water and air. Biochar is the carbonaceous, solid product of heating carbonaceous feedstock in an oxygen-limited environment above 250°C, usually sourced from inexpensive, locally available agricultural and forestry wastes which can otherwise be difficult and expensive to dispose of. Biochar possesses attractive functional properties like high specific surface area, high micropore volume, and …
