The production of fructose from carbohydrate feedstocks
A review of the general chromatographic theory and of continuous chromatographic techniques has been carried out. Three methods of inversion of sucrose to glucose and fructose in beet molasses were explored. These methods were the inversion of sucrose using the enzyme invertase, by the use of …

Development of biomaterials from sustainably produced macroalgae feedstocks
Upgrading and maintaining large-scale wastewater treatment plants (WWTPs) is notably expensive, particularly in rural areas of New Zealand. Freshwater macroalgae ponds may offer a cost-effective alternative for wastewater treatment in these areas. These ponds produce significant amounts of residual …

Optimization of the slag tap for the gasification of sustainable feedstocks
… of biomass and municipal solid waste feedstocks. Theoretical testing was conducted on the slag tapping block implementing computational fluid dynamics and design of experiments. It was desired to see how factors affecting the slag tap could be optimized to result in the minimum …

Engineering Zymomonas mobilis for efficient fuel ethanol production from lignocellulosic feedstocks
… production of fuel ethanol from lignocellulosic feedstocks due to its high ethanol productivity. Z. mobilis has been engineered to ferment all of the sugars present in cellulosic biomass, but the digestion of five carbon sugars by the strain is still slow and inefficient. The inefficiencies are …

Reaction mechanisms of hydrothermal liquefaction of model compounds and biowaste feedstocks
… lipid, protein and carbohydrates content in the feedstocks. A positive linear relationship was observed between the refined oil yield and the lipid content, as well as between the refined oil yield and the protein content. A negative linear relationship was found between the refined oil yield and …

Plastic and mixed waste as feedstocks for solar-driven H₂ production
As the world strives toward a carbon-neutral future powered by a circular economy, photoreforming enables the simultaneous generation of renewable fuel and mitigation of waste. In this simple process, a photocatalyst utilises the energy in sunlight to reduce water to H₂ and oxidise waste into other …

Operation of a High-Pressure Uncooled Plasma Torch with Hydrocarbon Feedstocks
… a plasma torch could operate on pure hydrocarbon feedstocks and, if so, to catalogue the torch operational characteristics. The future goal of the project is to design a plasma torch for supersonic combustion applications that operates off of the vehicle main fuel supply to simplify onboard fuel …

Cytogenetics and genome structure in genus Miscanthus, a potential source of bioenergy feedstocks
Miscanthus (subtribe Saccharinae, tribe Andropogoneae, family Poaceae) is a genus of temperate perennial C4 grasses. Accessions in the genus Miscanthus are potential crop candidates of lignocellulosic biomass for energy production, whose high biomass productivity is attractive as a biofuel …

Comparative systems analysis of thermochemical and biochemical recycling of organic waste towards industrial feedstocks
… for chemical and energy production from fossil feedstocks to renewable raw materials is seen by many as one of the key strategies towards sustainable development. The utilization of biomass for the production of fuels and materials has been proposed as an alternative to the petroleum-based …

Yield and quality of cool-season perennial grasses for forage and biomass feedstocks in Northeast Colorado
The burning of fossil fuels has led to an increase of the greenhouse gas CO2, which traps heat and increases temperatures of the global climate. The increases of the greenhouse gases, CO2, CH4 and N2O, have been attributed as the cause of the climatic warming during the industrial era. One …

Development of Catalytic Processes for the Transformation of Low Value Chemical Feedstocks to Value Added Chemicals
Dwindling oil reserves have necessitated the shift to alternative sources for fuels and commodity chemicals. This thesis describes fundamental studies and development of catalytic processes for the transformation of abundant, low value chemical resources into value added chemicals. Chapter 1 of …
