Maximizing biomass utilization: An integrated strategy for coproducing multiple chemicals

Journal of Energy Chemistry 2025年第1期100卷 180-191页

作者： Byeongchan Ahn Sua Jo Jonggeol Na J.Jay Liu Young-Ju Kim Wangyun Won Department of chemical and Biological Engineering Korea University Department of chemical Engineering (Integrated process) Kyung Hee University Department of chemical Engineering and Materials Science Ewha Womans University Department of chemical Engineering Pukyong National University Resources Engineering plant Research Department Korea Institute of Geoscience and Mineral Resources

Lignocellulosic biomass is one of the viable solutions to alleviate the global warming. However, the limited utilization of biomass majorly focused on cellulose and hemicellulose restricts the economic and environmental feasibilities. To cope with this issue, we proposed an integrated process of co-producing 1,6-hexanediol（1,6-HDO） with tetrahydrofuran and adipic acid from biomass, referred to as Strategy A. To compare the impacts of lignin upgrading and feedstock, Strategy B, which co-produces tetrahydrofuran alone, and Strategy C, which is the traditional route to produce 1,6-HDO from fossil fuels, were used. Heat networks are also designed to reduce operating costs and indirect carbon emissions due to energy consumption, saving 87% and 83% of the heat and cooling requirements, respectively, in Strategy A. The market competitiveness of Strategy A was evaluated by determining the minimum selling price through techno-economic analysis, and sustainability was thoroughly investigated by quantifying the environmental impacts through both midpoint and endpoint life-cycle assessments（LCAs）.Strategy A was found to be the most favorable both economically（USRDSCHARDOLLAR3,402/ton） and environmentally（-26.9 kg CO2eq.）. This indicates that lignin valorization is not only economically but also environmentally preferred. Finally, changes in economic and environmental feasibilities depending on economic, process, and environmental parameters were investigated using sensitivity and uncertainty analyses. The results of these analyses provide valuable insight into bio-based chemical production.

有机肥部分替代化肥是一种实现化肥减量的可持续农业生产措施。本研究于2020和2021连续2年以“沁黄2号”为供试材料,设不施氮(CK)、常量化肥氮(NPK)、有机肥替代25%化肥氮(25%M)、有机肥替代50%化肥氮(50%M)、有机肥替代75%化肥氮(75%M)和有机肥替代100%化肥氮(100%M) 6个处理,研究不同替代率对谷子产量构成和氮素吸收的影响,并分析氮素吸收调控小米米色、糊化特性和类胡萝卜素组分的效应,明确谷子生产中有机肥最佳替代率。结果表明,2年中较低的有机肥替代化肥氮率显著提高了谷子植株氮素累积,但随着替代率的持续增加,植株氮素累积量呈降低趋势,最终影响谷子产量和小米品质。2020年, 25%M处理显著提高了谷子地上部氮素累积量,较NPK处理提高9.6%;2021年,25%M处理谷子地上部氮素累积量、生物量、穗粒数和产量达到最高,较NPK处理分别提高6.1%、12.0%、15.4%和12.0%。50%M处理显著影响了小米的米色、糊化特征和类胡萝卜素含量,与NPK相比,小米籽粒红绿值、橘色值、支链淀粉含量、总淀粉含量、小米糊化最终黏度、叶黄素含量、玉米黄质含量和黄色素含量的增幅分别可达6.0%、6.0%、7.4%、4.3%、7.8%、20.7%、17.4%和2.8%。但有机肥完全替代化肥降低了谷子地上部氮素吸收、地上部生物量、穗粒数及谷子产量,也抑制了小米叶黄素和玉米黄质含量的提升。2年均表现出谷子地上部氮吸收量与小米单粒重、直链淀粉含量和小米糊化回升值呈显著的负相关。且2021年谷子地上部氮吸收量还与小米总淀粉含量、蛋白质含量、小米粉糊化峰值黏度和小米黄色素含量呈显著的负相关,与小米糊化峰谷黏度呈显著的正相关。综上,施氮总量120 kg hm^(–2)下,有机肥替代25%~50%化肥氮能通过促进植株氮素的吸收,实现产量、米色、蒸煮特性及类胡萝卜素的协同提升,为谷子化肥减量和提质增效生产提供技术支撑。

Journal of Environmental Sciences 2013年第8期25卷 1565-1574页

作者： Xuewen Jin Enchao Li Shuguang Lu Zhaofu Qiu Qian Sui State Environmental Protection Key Laboratory of Environmental Risk Assessment and Control on chemical Process East China University of Science and Technology Shanghai Baosteel chemical Co. Ltd.

A full-scale plant using anaerobic, anoxic and oxic processes （A1/A2/O）, along with a pilot-scale membrane bioreactor （MBR）, nanofiltration （NF） and reverse osmosis （RO） integrated system developed by Shanghai Baosteel chemical Co. Ltd., was investigated to treat coking wastewater for industrial reuse over a period of one year. The removals reached 82.5% （COD）, 89.6% （BOD）, 99.8% （ammonium nitrogen）, 99.9% （phenol）, 44.6% （total cyanide （T-CN））, 99.7% （thiocyanide （SCN-）） and 8.9% （fluoride）, during the A1/A2/O biological treatment stage, and all parameters were further reduced by over 96.0%, except for fluoride （86.4%）, in the final discharge effluent from the currently operating plant. The pilot-scale MBR process reduced the turbidity to less than 0.65 NTU, and most of the toxic organic compounds were degraded or intercepted by the A1/A2/O followed MBR processes. In addition, parameters including COD, T-CN, total nitrogen, fluoride, chloride ion, hardness and conductivity were significantly reduced by the NF-RO system to a level suitable for industrial reuse, with a total water production ratio of 70.7%. However, the concentrates from the NF and RO units were highly polluted and should be disposed of properly or further treated before being discharged.

China Petroleum Processing & Petrochemical Technology 2006年第4期 23-28页

作者： Pan Maohua (Zhenhai Refining and chemical stock company, Ltd., Ningbo 315207) Zhenhai Refining and chemical stock company Ltd. Ningbo 315207 China

A novel environmentally friendly sulfiding agent SZ 54 was for the first time used for presulfidation of the catalyst in the 2 Mt/a hydrofining unit at Zhenhai Refining and chemical company. The application results had shown that the sulfiding agent SZ54 had low smell, high flash point, and safe and environmentally friendly features. The lower decomposition temperature and stepwise chemical decomposition characteristics of this reagent can effectively avoid the reduction of metals and improve sulfur adsorption to meet the needs for sulfidizing the hydrofining catalyst, and is a good reagent worthy of extended application.
