Sorghum is an important crop that serve multiple purposes as human food, animal feed, and bioenergy production. There are opportunities to produce different types of biofuels from sorghum-based biomass. Sorghum with its vast genetic resources can serve as bioenergy crop and not compete against the value of it as food and nutritional security crop. Bioenegy crops provides an opportunity for agriculture to be part of solution for energy and mitigation to climate change. This review provides detailed overview and current knowledge on the conversion of sorghum biomass (stalks, leaves, and grains) into liquid (bioethanol, biodiesel, and bio-oil), gas (biohydrogen, biogas, and syngas) and solid (biochar) biofuels. Progress made in the different sorghum-based biomass pretreatment and conversion processes including chemical, biochemical, thermochemical and biological processes (e.g. saccharification, fermentation, transesterification, hydrothermal liquefaction, pyrolysis, and gasification) are highlighted and described. In addition, several value-added products from sorghum gaining importance in biofuels production are summarized. Finally, the potential outlook on sorghum based biorefiners and potential for improving sorghum-based biofuel production is presented and discussed. The biorefinery concept offers a considerable scope for optimization of sorghum biomass utilization to produce biofuels and biochemicals. However, there is further need to clearly identify the best methods of pre-treatment, processing, and products from different sources. Sorghum with its high biomass production and multiple use has the potential to be key biofuel crop. Further research is needed to identify most efficient and cost effective processes to ensure the value of biofuel and other bioproducts from sorghum. A complete lifecycle analyses indicating the challenges and opportunities to enhance the efficiency, benefits, and challenges in different steps and finding solutions to overcome those challenges will be of prime importance. Strong collaboration between private and public sector researhcers and multidisciplinary teams will be required to develop a comprehensive biorefinery models.

用高粱生产生物燃料

高粱是一种重要的作物,具有多种用途,如人类食物,动物饲料和生物能源生产。有机会从高粱基生物质生产不同类型的生物燃料。高粱具有丰富的遗传资源,可以作为生物能源作物,不能与它作为粮食和营养安全作物的价值竞争。生物能源作物为农业提供了机会,成为解决能源问题和缓解气候变化的一部分。这篇综述提供了有关高粱生物质(茎,叶和谷物)转化为液体(生物乙醇,生物柴油和生物油),气体(生物氢,沼气和合成气)和固体(生物炭)生物燃料的详细概述和当前知识。 。在基于高粱的生物质预处理和转化过程中,包括化学,生化,重点介绍了热化学和生物学过程(例如糖化,发酵,酯交换,水热液化,热解和气化)。此外,总结了几种高粱的增值产品在生物燃料生产中的重要性。最后,介绍并讨论了基于高粱的生物精炼机的潜在前景以及提高基于高粱的生物燃料生产的潜力。生物精炼概念为优化高粱生物质利用以生产生物燃料和生化物质提供了广阔的空间。但是,进一步需要清楚地确定预处理,加工和来自不同来源的产品的最佳方法。高生物量生产和多种用途的高粱有可能成为重要的生物燃料作物。需要进一步的研究来确定最有效和最具成本效益的过程,以确保高粱的生物燃料和其他生物产品的价值。完整的生命周期分析将表明在不同步骤中提高效率,收益和挑战所面临的挑战和机遇,并找到解决这些挑战的解决方案至关重要。私人和公共部门再培训者和多学科团队之间需要强有力的合作,以开发综合的生物精炼模型。采取不同步骤应对挑战,寻找克服这些挑战的解决方案至关重要。私营和公共部门再培训者和多学科团队之间需要强有力的合作,以开发综合的生物精炼模型。采取不同步骤应对挑战,寻找克服这些挑战的解决方案至关重要。私营和公共部门再培训者和多学科团队之间需要强有力的合作,以开发综合的生物精炼模型。
