This book was released on 1998 with total page 268 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper evaluates the economic feasibility and economy-wide impacts of the U.S. ethanol production from lignocellulosic feedstocks (LCF) using Tennessee Valley Authority's (TVA's) dilute acid hydrolysis process. A nonlinear mathematical programming model of a single ethanol producer, whose objective is profit maximization, is developed. Because of differences in their chemical composition and production process, lignocellulosic feedstocks are divided into two groups: Biomass feedstocks, which refer to crop residues, energy crops and woody biomass, and municipal solid waste (MSW). Biomass feedstocks are more productive and less costly in producing ethanol and co-products, while MSW generates an additional income to the producer from a tipping fee and recycling. The analysis suggests that, regardless of types of feedstocks used, TVA's conversion process can enhance the economic viability of ethanol production as long as furfural is produced from the hemicellulose fraction of feedstocks as a co-product. The high price of furfural makes it a major factor in determining the economic feasibility of ethanol production. Along with evaluating economic feasibility of LCF-to-ethanol production, the optimal size of a plant producing ethanol using TVA's conversion process is estimated. The larger plant would have the advantage of economies of scale, but also have a disadvantage of increased collection and transportation costs for bulky biomass from more distant locations. We assume that the plant is located in the state of Missouri and utilizes only feedstocks produced in the state. The results indicate that the size of a plant using Biomass feedstocks is much bigger than one using MSW. The difference of plant sizes results from plant location and feedstock availability. One interesting finding is that energy crops are not feasible feedstocks for LCF-to-ethanol production due to their high price. Next, a static CGE model is developed to estimate the U.S. economy-wide impacts of the current ethanol production with a government subsidy and the LCF-to-ethanol production using TVA's dilute acid hydrolysis process. The model is innovative in three ways. First, a production subsidy is explicitly included in the model. Second, co-products are explicitly accounted for in ethanol production. Third, ethanol and gasoline are treated as perfect demand substitutes, as are the co-products and the manufacturing sector's output. The CGE model shows that current ethanol production expands grain crop production by creating an additional demand. In contrast, LCF-to-ethanol production has adverse impacts on grain crop production because Biomass feedstocks substitute for grain in the production of ethanol. The LCF-to-ethanol production also discourages the manufacturing industry because co-products displace a part of intermediate input demand for manufacturing outputs. It is also found that, even though ethanol production using TVA's conversion technology with MSW is economically viable, it is not favorable to the economy. Finally, the results suggest that ethanol production from Biomass feedstocks using TVA's dilute acid hydrolysis process is beneficial to the U.S. economy.

Download or read book Biochemical Conversion of Lignocellulosic Biomass to Ethanol written by Deepak Kumar and published by . This book was released on 2014 with total page 207 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ethanol production from lignocellulosic feedstock has been under intense scrutiny as a transportation fuel due to its potential to address concerns of increasing energy consumption, limited fossil energy resources, climate changes due to greenhouse gas emissions from fossil fuels, and especially use of non-food biomaterials, which address the biggest limitation of first generation bioethanol. Despite these advantages, the lignocellulosic ethanol production on commercial scale is still on verge because of high processing costs of ethanol production. In the biochemical conversion process, biomass is converted to ethanol by sequential steps of pretreatment (to reduce the recalcitrance of biomass), hydrolysis (conversion of sugar polymers to monomers) and fermentation (sugars to ethanol). Every year, about a million ton of grass straw is available as agricultural residue in Pacific Northwest. There were no previous comprehensive studies to evaluate the technical feasibility, economic viability and environmental sustainability of the bioethanol produced using grass straw in Willamette valley. The focus of this dissertation was to investigate the potential of cellulosic ethanol production from grass straw, assess the techno-economic viability and environmental impacts of the bioethanol production and development of a stochastic molecular model for modeling cellulose hydrolysis. This dissertation was divided into four studies focused on individual aspects of the overall objective. The first study evaluated the ethanol production potential from straws produced from three major grass seed varieties (perennial ryegrass (Lolium perenne L.), tall fescue (Festuca arundinacea Schreb) and bentgrass (Agrostis sp.)) in Pacific Northwest. Feedstocks were pretreated using three chemical pretreatments (dilute acid, dilute alkali, and hot water) and subsequently hydrolyzed enzymatically to investigate the effect of pretreatment and estimate the potential ethanol yields. Carbohydrate content in biomass varied from 40.6 to 52.9%, with tall fescue having the maximum cellulose content of 32.4%. All pretreatment were effective in increasing the hydrolysis yields, and theoretical maximum ethanol yields were in the range of 276 to 360 L per ton of biomass. The second study performed the comprehensive techno-economic analysis of ethanol production from tall fescue using dilute acid, dilute alkali, hot water, and steam explosion pretreatment technologies. Detailed process models incorporating all unit operations in lignocellulosic ethanol plant with 250,000 metric ton biomass/ year processing capacity were developed in SuperPro Designer. The ethanol production cost were estimated from $0.81 to $0.88/ L of ethanol, and were found highly sensitive to biomass price, enzyme cost, and pentose sugar fermentation efficiency. Energy from lignin residue burning was found sufficient to meet the steam requirement in the production process. Third study performed the life cycle assessment for bioethanol production from grass straw considering various pretreatment technology options. The study revealed that ethanol production from grass straw provide environmental benefits compared to use of gasoline, with 57.43-112.67% reduction in fossil energy use to produce 10,000 MJ of fuel. The GHG emissions during life cycle of ethanol production were estimated in the range of -131 to -555.4 kg CO2 eq. per 10,000 MJ of fuel. It was observed that assumptions and allocation procedure used during the analysis had a significant effect on the LCA results. During the techno-economic assessment of bioethanol process, it was found that cost of cellulose enzymes was significant fraction of the total ethanol production cost. A comprehensive enzymatic hydrolysis model can play critical role in optimizing the enzyme composition and dosage, improving understanding of the process mechanism and reducing the cost of enzymes, a major bottleneck in the ethanol production process. A novel approach of stochastic molecular modeling, in which each hydrolysis event is translated into a discrete event, was used to develop a mechanistic model for cellulose hydrolysis in the fourth study. Cellulose structure was modeled as a group of microfibrils consisting of elementary fibrils bundles, where each elementary fibril was represented as a three dimensional matrix of glucose molecules. Major structural properties: crystallinity, degree of polymerization, surface accessibility, and enzyme characteristics: mode of action, binding and surface blockage, inhibition, along with the dynamic morphological changes in structure of cellulose were incorporated in the model. Hydrolysis of cellulose was simulated based on Monte Carlo simulation technique. Hydrolysis results predicted by model simulations had shown a good fit with the experimental data from hydrolysis of pure cellulose using purified enzymes for various hydrolysis conditions. The model was effective in capturing the dynamic behavior of cellulose hydrolysis during action of individual as well as multiple cellulases. Model was able to simulate and validate all the important expected experimental observations: effect of structural properties, enzyme inhibition and enzyme loadings on the hydrolysis and degree of synergism on different substrates. The work from this dissertation proved the significance of choosing technology options, drew a comparison among different pretreatment technologies, identified the critical processes and inputs that have significant effect on the ethanol production cost, net energy, and GHG emissions. Results from the last study confirmed the validity of using the stochastic molecular modeling approach to quantitatively and qualitatively describe the cellulose hydrolysis, which has wide potential application in bioethanol production research to reduce the enzyme cost.

Available in PDF, EPUB and Kindle. Book excerpt: The mature corn-to-ethanol industry has many similarities to the emerging lignocellulose-to-ethanol industry. It is certainly possible that some of the early practitioners of this new technology will be the current corn ethanol producers. In order to begin to explore synergies between the two industries, a joint project between two agencies responsible for aiding these technologies in the Federalgovernment was established. This joint project of the USDA-ARS and DOE/NREL looked at the two processes on a similar process design and engineering basis, and will eventually explore ways to combine them. This report describes the comparison of the processes, each producing 25 million annual gallons of fuel ethanol. This paper attempts to compare the two processes as mature technologies, whichrequires assuming that the technology improvements needed to make the lignocellulosic process commercializable are achieved, and enough plants have been built to make the design well-understood. Assumptions about yield and design improvements possible from continued research were made for the emerging lignocellulose process. In order to compare the lignocellulose-to-ethanol process costs withthe commercial corn-to-ethanol costs, it was assumed that the lignocellulose plant was an Nth generation plant, built after the industry had been sufficiently established to eliminate first-of-a-kind costs. This places the lignocellulose plant costs on a similar level with the current, established corn ethanol industry, whose costs are well known. The resulting costs of producing 25 millionannual gallons of fuel ethanol from each process were determined. The figure below shows the production cost breakdown for each process. The largest cost contributor in the corn starch process is the feedstock; for the lignocellulosic process it is the capital cost, which is represented by depreciation cost on an annual basis.
