摘要: Abstract This study examines the integration of commercial liquid fuels production from biomass using alcohol-to-jet pathway into a conventional kraft pulp mill operation. Mill assets including feed handling and supply chain infrastructure, power recovery systems, potential equipment retrofitting opportunities are utilized by fuel unit through lignocellulosic ethanol fermentation processing. Potential economic benefits integrating energy system (recovery boiler) with pretreatment systems evaluated mass balances integrated facility. Process variations explored within this model include use hemicellulose pre-extraction or black liquor fractionation, modifications to digester operations scale project. The is found provide relative reduction in compared production. With low costs provided design, maintaining high yield throughout conversion process capital offer best for further improving economics. Although viability realistic biorefinery not directly study, aim identify technical barriers development strategies implementing proven biofuels technologies.
