Report Abstract
This study presents a techno-economic analysis of cellulosic Isobutanol production from corn stover in the United States using a biochemical process. Initially, corn stover is treated with dilute acid and undergoes ammonia conditioning. Then, the cellulose is enzimatically hydrolyzed to glucose and xylose, which are then fermented to produce Isobutanol.
The report provides a comprehensive study of Isobutanol production and related Isobutanol production cost, covering three key aspects: a complete description of the Isobutanol production process examined; an in-depth analysis of the related Isobutanol plant capital cost (Capex); and an evaluation of the respective Isobutanol plant operating costs (Opex).
The Isobutanol production process description includes a block flow diagram (BFD), an overview of the industrial site installations, detailing both the process unit and the necessary infrastructure, process consumption figures and comprehensive process flow diagrams (PFD). The Isobutanol plant capital cost analysis breaks down the Capex by plant cost (i.e., ISBL, OSBL and Contingency); owner's cost; working capital; and costs incurred during industrial plant commissioning and start-up. The Isobutanol plant operating costs analysis covers operating expenses, including variable costs like raw materials and utilities, and fixed costs such as maintenance, labor, and depreciation.
Process Overview

Product
Isobutanol. Isobutanol (a.k.a. 2-Methylpropan-1-ol, i-BuOH, Bio-Isobutanol) is a colorless, flammable alcohol with a characteristic smell and fields of application closely resembling those of 1-butanol. Isobutanol may also be produced from renewable sources and, in such cases, it may be referred to as Bio-Isobutanol or Green Isobutanol.
Raw Material
Corn Stover. Corn Stover consists of the leaves, stalks, and cobs remaining after corn is harvested. It is utilized as animal feed, biomass for energy production, and as a raw material for biofuel and bioproducts. Collected from fields post-harvest, corn stover is typically stored in bales. Its use in cellulosic ethanol production contributes to renewable energy efforts and adds value to agricultural residues.

Ethanol from Corn Stover (Digestion with SO2-Ethanol-Water Solution)
This report presents a techno-economic analysis of second generation Ethanol production from corn stover in the United States using a process similar to AVAP technology, developed by American Process. In this process, biomass is fractionated into cellulose, hemicelluloses and lignin by using a sulfur dioxide-ethanol-water solution. The cellulose and hemicelluloses obtained from biomass are converted to monomeric sugars, which are then used to produce Ethanol via fermentation.
