  • Optimal design of an efficient, profitable and sustainable Biorefinery producing acetone, butanol and ethanol: influence of the in-situ separation on the purification structure
    Biochemical Engineering Journal, 2016
    Co-Authors: Ségolène Belletante, Ludovic Montastruc, Stéphane Négny, Serge Domenech
    Abstract:

    The bio-based n-butanol has major potential to replace fossil-based products due to, on the first hand, the decline of crude oil and, on the other hand, since the butanol has high potential as fuel. To set its production in industrial scale the development of tools designing the process is needed. In our work, we focus on Second Generation Biorefinery using wood as feedstock. The Biorefinery was composed by the pretreatment, the hydrolysis, the fermentation, the butanol recovery and the purification. The proposed methodology is a multiscale decision support tool for the selection of the optimal process design of the Biorefinery producing biobutanol. The optimal Biorefinery is selected from the superstructure recapping all feasible scenarios after process modelling and simulation, economic and environmental evaluations and energy integration. Thus, the optimal process is profitable, efficient and sustainable. Moreover, to identify the influence of the biobutanol recovery on the fermentation’s performances, the process modelling includes the retroaction of biobutanol recovery. In this study, three biobutanol recovery and four purification scenarios are combined and then processes are compared to select the optimal Biorefinery for the bio based butanol production.

  • Lignin from Second-Generation Biorefinery for pressure-sensitive adhesive tapes
    Biomass Conversion and Biorefinery, 2019
    Co-Authors: Xihua Hu, Aleksa Hadzi-ristic, Christian Kreft, Cai Rong Lim, Carsten Zetzl, Joana Gil-chávez, Irina Smirnova
    Abstract:

    In this work, the potential of lignin as a filler additive and anti-aging agent in a pressure-sensitive adhesive (PSA) based on natural rubber (NR) was investigated. Herein, different approaches to incorporate lignin into NR matrix by adaptation of a two-step compounding process were evaluated. At first, a twin-screw extruder (TSE) was utilized to prepare pre-formulations followed by the Secondary finalization of adhesive mass inside a planetary roll extruder (PRE). For the industrial production of PSAs, the adhesive mass is required to have well-distributed additive materials and adequate adhesion, cohesion, and longevity. The impact of the added lignin was evaluated concerning optical appearance, compatibility between lignin and rubber/resin, adhesion performance, shear strength, thermal stability, antioxidant capability, dynamic-mechanical behavior, aging behavior at elevated temperature and under UV exposure, and filler morphology. It was found that the PSAs including aquasolv (AS) lignin after the spray-drying post-treatment exhibited excellent thermal, mechanical, and antioxidative properties. Thus, it was shown that the sustainably producible lignin can be utilized both as filler and antioxidant in natural rubber-based pressure-sensitive adhesive masses with comparable performance properties as commercially available products.

  • comparison of pretreatment methods for rye straw in the Second Generation Biorefinery effect on cellulose hemicellulose and lignin recovery
    Bioresource Technology, 2013
    Co-Authors: Lilia Perezcantu, Bodo Saake, Andreas Schreiber, Fokko Schutt, Christian Kirsch, Irina Smirnova
    Abstract:

    The increasing interest in lignocellulose-based biorefineries boosts the further development of the needed pretreatment methods for preprocessing biomass. There are a large number of different processes that are being investigated; however research is made mostly based on different types of biomass with the same pretreatment or several modifications of the same process for a given type of biomass. In this work a comparison of promising chemical pretreatments using the same biomass was performed. Organosolv (OS), Steam (SE) and Liquid-Hot-Water (LHW) processes were used for the pretreatment of rye straw and the treated solids further enzymatically hydrolyzed. Best results for carbohydrate and lignin yield were found for the OS pretreatment followed close by the LHW and SE with similar results. All of the processes showed satisfactory performance for the pretreatment of lignocellulosic biomass for application in the Second Generation Biorefinery.
