phd thesis in bioethanol production

This thesis comprises the research done during a PhD project carried out at the Department of Environmental Engineering, Technical University of Denmark, from November 1, 2008 to March 31, 2013. Professor Irini Angelidaki was the main supervisor; Senior Researcher Dimitar Karakashev was the co-supervisor.

1. Introduction. Fossil fuels, the predominant energy source, emit harmful gases and particulate matter upon use, causing environmental damage. This prompted the search for cleaner fuels like bioethanol as it limits the emission of SOx and particulate matter [1].Bioethanol is used as a source of energy, mainly as a blend in gasoline [2].It can also be used potentially for producing sustainable ...

The results of this work reveal that the optimal bioethanol production plant capacity is 2800 MT biomass/day utilizing Ammonia Fiber Explosion pretreatment technology and corn stover as the preferred biomass feedstock. This configuration provides a minimum ethanol price of $1.96/gal. Results also show that this optimal

1. Introduction. Development of bioethanol production is an essential strategy to assure energy security. Therefore, adoption of bioethanol manufacturing is being considered in many countries, though food security policies limit its implementation [1].Bioethanol obtained from alternative biomass routes has offered important benefits by reducing greenhouse gas emissions.

The second-generation biofuels are produced from lignocellulosic biomass (LB) including energy grasses, crops, and wood residues. Bioethanol production from LB is gaining attention due to its high availability, positive environmental impact, and economic potential (Bilal et al., 2017).In 2018, the total bioethanol production from under development pilot-scale facilities was 110 billion liters ...

This dissertation focuses on 2nd generation bioethanol production from lignocellulosic biomass. The first part of this thesis examined the enzymatic production of fennentable sugars from a range of lignocellulosic biomass and agricultural residues e.g. miscanthus, switchgrass, reedcanary grass, wheat straw, cassava peel and millet straw.

Abstract: The overall objective of the study was to produce bioethanol from lignocellulosic biomass by using free and immobilized xylanase, cellulase and β-1, 3-glucanase. Specifically, this study was focused on the isolation of. Trichoderma citrinoviride.

Bioethanol used for commercial purposes is usually produced from edible feedstocks such as corn and sugar cane which increases the production cost. The high cost of these feedstocks is the driving ...

In this paper, a simulation model based on the non-stoichiometric equilibrium method via ASPEN Plus was established to analyze the gasification performance of 20 herbaceous and agricultural biomasses (H&ABs) linked with syngas fermentation and product purification units for ethanol production. The established simulation model does not consider the gasification system as a black box; it focuses ...

In conclusion, this thesis has demonstrated that up to ca. 20 g l-1 of ethanol can be produced from kelp species that grow on the west coast of Scotland. The procedure developed and used to produce ethanol requires further development, specifically the need for ethanol-fermenting microorganisms that can utilize mannitol and alginate; use of ...
