Title: Technoeconomic Analysis of a Lignocellulosic Biomass Indirect Gasification Process to Make Ethanol via Mixed Alcohols Synthesis

Abstract

A technoeconomic analysis of a 2000 tonne/day lignocellulosic biomass conversion process to make mixed alcohols via gasification and catalytic synthesis was completed. The process, modeled using ASPEN Plus process modeling software for mass and energy calculations, included all major process steps to convert biomass into liquid fuels, including gasification, gas cleanup and conditioning, synthesis conversion to mixed alcohols, and product separation. The gas cleanup area features a catalytic fluidized-bed steam reformer to convert tars and hydrocarbons into syngas. Conversions for both the reformer and the synthesis catalysts were based on research targets expected to be achieved by 2012 through ongoing research. The mass and energy calculations were used to estimate capital and operating costs that were used in a discounted cash flow rate of return analysis for the process to calculate a minimum ethanol selling price of $0.267/L ($1.01/gal) ethanol (U.S.$2005).
