Effects of temperature, flow rate, number of stages and a heads column on congener removal in fuel‐ethanol distillation: a simulation study

Journal of Chemical Technology &Biotechnology, Volume 101, Issue 4, Page 726-739, April 2026.
Abstract BACKGROUND Industrial fuel‐ethanol units must remove trace volatile congeners (acetaldehyde, ethyl acetate, carbon dioxide) to meet quality requirements. In Brazilian systems, a small heads column (“Column D”) is often placed above the stripper.

Techno‐economic analysis for hydroxy acids production from waste cellulose via alkaline digestion

Journal of Chemical Technology &Biotechnology, Volume 101, Issue 4, Page 904-914, April 2026.
Abstract BACKGROUND Alkaline digestion offers a promising route for converting low‐grade cellulosic wastes into valuable hydroxy carboxylic acids (HAs). However, the feasibility of producing HAs at process scale, particularly the influence of reactor design on product yields, energy demand, and production costs, remains less explored.

Volumetric mass transfer and dilution rate as key parameters for sustainable industrial syngas fermentation to isopropyl alcohol: modeling and parametric assessment

Biofuels, Bioproducts and Biorefining, Volume 20, Issue 2, Page 473-486, March/April 2026.
Abstract Synthesis gas fermentation is a promising route for the valorization of steel mill off‐gas and for replacing conventional fossil‐based isopropyl alcohol (IPA) production. A recent 120 L pilot‐scale study reported 85% gas conversion at 90% product selectivity and claimed a negative global warming potential (GWP) without detailed process design.
