This work investigated a model biorefinery for producing phenolic compounds extract, ethanol and xylitol from spent blackberry pulp (SBP). The biorefinery was investigated according to four potential scenarios including mass and heat integrations as well as cogeneration system for supplying part of the energy requirements in the biorefinery. The investigated SBP had 61.54% holocellulose; its total phenolic compounds was equivalent to 2700mg of gallic acid/100g SBP, its anthocyanins content was 126.41mg/kg of SBP and its total antioxidant activity was 174.8μmol TE/g of SBP. The economic analysis revealed that the level of integration in the biorefinery significantly affected the total production cost. The sale-to-total-production-cost ratio indicated that both, mass and heat integrations are of importance relevance. The cost of supplies (enzymes and reagents) had the most significant impact on the total production cost and accounted between 46.72 and 58.95% of the total cost of the biorefinery.
本工作研究了从黑莓渣(SBP)中生产酚类化合物提取物、乙醇和木糖醇的模型生物炼制厂。根据四个潜在情景对生物炼制厂进行了调查,包括质量和热量集成以及热电联产系统,以供应生物炼制厂部分能源需求。所研究的 SBP 含有 61.54%的全纤维素;其总酚类化合物相当于 2700mg 没食子酸/100g SBP,其花青素含量为 126.41mg/kg SBP,总抗氧化活性为 174.8μmol TE/g SBP。经济分析表明,生物炼制厂的集成水平对总生产成本有显著影响。销售与总生产成本的比率表明,质量和热量集成都具有重要意义。供应成本(酶和试剂)对总生产成本的影响最大,占生物炼制厂总成本的 46.72%至 58.95%。
