Ethanol Production from Wood Chips - Cost Analysis - Ethanol E54A


Book Description

This report presents a cost analysis of second generation Ethanol production from wood chips via a thermochemical process. In this process, biomass is subjected to gasification generating syngas. From syngas, methanol and then dimethyl ether (DME) are synthesized. Finally, DME undergoes a hydrocarbonylation reaction generating hydrous Ethanol product. This report was developed based essentially on the following reference(s): Keywords: Ethyl Alcohol, Bioethanol, Lignocellulosic Biomass, 2nd Generation




Cellulosic Ethanol from Wood Chips - Cost Analysis - Ethanol E51A


Book Description

This report presents a cost analysis of second generation Ethanol production from wood chips via a thermochemical process. The process examined is similar to the one reported by the National Renewable Energy Laboratory (NREL). In this process, biomass is subjected to gasification generating syngas, which is then converted to hydrous Ethanol. The process employs concepts similar to those proposed in patents issued to Range Fuels. Mixed alcohols are generated as by-products. This report was developed based essentially on the following reference(s): Phillips, S., et al., "Thermochemical Ethanol via Indirect Gasification and Mixed Alcohol Synthesis of Lignocellulosic Biomass, " Report NREL/TP-510-41168, National Renewable Energy Laboratory (NREL), 2007 Keywords: Ethyl Alcohol, Bioethanol, Lignocellulosic Biomass, 2nd Generation, Cellulosic Sugar, Hemicelluloses, Cellulose




Cellulosic Ethanol from Wood Chips - Cost Analysis - Ethanol E52A


Book Description

This report presents a cost analysis of second generation Ethanol production from wood chips using a biochemical conversion process. The process examined is similar to AVAP technology, developed by American Process. In this process, biomass is fractionated into cellulose, hemicelluloses and lignin. The hemicellulose and cellulose are converted to monomer sugars, which are then fermented to produce hydrous Ethanol, while lignin is burned to generate electricity. This report was developed based essentially on the following reference(s): WO Patent 2011044378, issued to American Process in 2011 Keywords: Ethyl Alcohol, Bioethanol, Lignocellulosic Biomass, 2nd Generation, Cellulosic Sugar, Hemicelluloses, Cellulose




Cellulosic Ethanol from Wood Chips - Cost Analysis - Ethanol E53A


Book Description

This report presents a cost analysis of second generation Ethanol production from wood chips using a biochemical conversion process. The process examined is similar to GreenPower, developed by American Process. In this process, hemicelluloses are extracted from biomass and used to produce hydrous Ethanol. The rest of the biomass is burned to generate electricity. In addition, a potassium acetate solution is also generated as by-product. This report was developed based essentially on the following reference(s): US Patent 20110195468, issued to American Process in 2011 Keywords: Ethyl Alcohol, Bioethanol, Lignocellulosic Biomass, 2nd Generation, Cellulosic Sugar, Hemicelluloses, Cellulose




Ethanol Production from Sugarcane - Cost Analysis - Ethanol E72F


Book Description

This report presents a cost analysis of hydrous Ethanol from sugarcane using a typical process. In this process, sucrose is extracted from sugarcane and it is fermented to produce hydrated Ethanol. The sugarcane bagasse is burned for electricity generation. This report was developed based essentially on the following reference(s): "Ethanol", Ullmann's Encyclopedia of Industrial Chemistry, 7th edition Keywords: Ethyl Alcohol, Bioethanol, Biomass




Ethanol Production from Corn Dry Milling - Cost Analysis - Ethanol E41A


Book Description

This report presents a cost analysis of hydrous Ethanol production from corn. The process examined is a typical dry milling process. In this process, Distiller's Dried Grain with Solubles (DDGS) is generated as by-product. This report examines one-time costs associated with the construction of a United States-based plant and the continuing costs associated with the daily operation of such a plant. More specifically, it discusses: * Capital Investment, broken down by: - Total fixed capital required, divided in production unit (ISBL); infrastructure (OSBL) and contingency - Alternative perspective on the total fixed capital, divided in direct costs, indirect costs and contingency - Working capital and costs incurred during industrial plant commissioning and start-up * Production cost, broken down by: - Manufacturing variable costs (raw materials, utilities) - Manufacturing fixed costs (maintenance costs, operating charges, plant overhead, local taxes and insurance) - Depreciation and corporate overhead costs * Raw materials consumption, products generation and labor requirements * Process block flow diagram and description of industrial site installations (production unit and infrastructure) This report was developed based essentially on the following reference(s): "Ethanol", Ullmann's Encyclopedia of Industrial Chemistry, 7th edition Keywords: Ethyl Alcohol, Bioethanol, Biomass




The Economic Impact of the Demand for Ethanol


Book Description

Ethanol production is the third-largest user of corn, behind only feed & export uses. Ethanol production uses approximately 7% of the nation's corn crop which increases farm income & generates economic activity nationwide. This report is the first comprehensive analysis of the macroeconomic impacts of ethanol production. The conclusions in this report verify the cost-effectiveness of the federal ethanol program. In short, the partial excise tax exemption provided for ethanol blends is a non-inflationary incentive that creates jobs, stimulates tremendous economic activity, & reduces our trade imbalance.
