Techno-economic analysis for upgrading the biomass-derived ethanol-to-jet blendstocks

Abstract

This study summarizes the detailed techno-economic analysis of the ethanol-to-jet (ETJ) process based on two different feedstocks (corn grain and corn stover) at the plant scale of 2000 dry metric tons per day.

Techno‐economic analysis of co‐production of 2,3‐butanediol, furfural, and technical lignin via biomass processing based on deep eutectic solvent pretreatment

“…Total installation cost (TIC) was the cost of equipment purchased (C) multiplied by a ratio (R) of 1.5–2.6, and the total direct cost (TDC) was the sum of total installation cost and additional inside battery limits (ISBL) equipment cost (associated with DES pretreatment area, furfural production and distillation area, and 2,3‐BDO production and distillation area) . The indirect cost (IDC) was assumed to be 60% of the direct cost .…”

“…Total installation cost (TIC) was the cost of equipment purchased (C) multiplied by a ratio (R) of 1.5-2.6, and the total direct cost (TDC) was the sum of total installation cost and additional inside battery limits (ISBL) equipment cost (associated with DES pretreatment area, furfural production and distillation area, and 2,3-BDO production and distillation area). 15,23 The indirect cost (IDC) was assumed to be 60% of the direct cost. 23 Finally, the total capital investment (TCI) was evaluated by the summation of the direct cost, indirect cost, land cost, and working capital, of which the land cost was scaled from the NREL report, 23 and the working capital was considered as 5% of the combined direct and indirect costs.…”

“…The TEA of lignocellulosic biomass conversion into platform chemicals and biofuels has been studied extensively. [15][16][17] Compared to ethanol and butanol production, 2,3-BDO production can achieve high concentrations (up to 152 g L −1 ) and volumetric productivities (up to 4.2 g L −1 ·h) due to lower inhibitory effects of product on 2,3-BDO-producing strains. 18 The high fermentation efficiency of 2,3-BDO suggests the feasibility of its industrial implementation.…”

Valorization of aqueous waste streams from thermochemical biorefineries

“…To realize circularity, technologies with renewably sourced feedstocks that produce material precursors and enable materials recycling must be established. Biomass conversion offers unique benefits relative to other renewable technologies in that (1) it produces fungible vehicle and aviation fuels, [3][4][5] (2) specialty and commodity chemical co-products can be concomitantly produced with biofuels, [6][7][8] (3) and some of the conversion operations can be applied to municipal solid waste recycling. 9 Biomass-derived chemicals as a source for material feedstocks is an active and broad area of research with significant efforts that span a wide range of feed substrates (e.g., whole lignocellulosic, lignin-only, sugars, cellulose, etc.)…”

An optimization‐based web application for synthesis and analysis of biomass‐to‐fuel strategies

“…Advances in fundamental research have resulted in the development of numerous biomass‐to‐fuels strategies. The abundant ‐biomass, including energy crops and biomass wastes, can be deconstructed and converted to biofuels ‐biochemically, catalytically, or thermo‐chemically . Evaluation of these strategies is key in identifying major cost drivers and bottlenecks for biofuel production.…”
