Abstract

The world's energy requirement is rising continuously due to an increase in the global population and demand for better quality of life. Fossil fuels are non-renewable, and their consumption poses global warming. Biomass-derived fuels are sustainable alternatives to fossil fuels as they are originated from renewable feedstocks. The present study investigates the production of biocrude from hydrothermal liquefaction of Canadian agricultural straws at identical conditions. Further, barley straw is found to be promising; therefore, hydrothermal liquefaction process parameters are varied for barley straw to maximize the biocrude yield with lower oxygen content. At optimum reaction conditions, the existence of carboxylic acids, phenols, aldehydes, and ketones is identified in the produced biocrude. Further, the recyclability study of the aqueous phase is attempted to explore the possibility of reusing this phase. The physicochemical characteristics of the biocrude (main product) and by-products (hydrochar, non-condensable gases, and aqueous phase) are also studied to identify the suitable areas of applications. The present experimental study demonstrates a detailed understanding of the liquefaction behavior of Canadian barley straw for biocrude production with an immense potential to co-refine in the existing petroleum refineries.

利用加拿大农业生物质生产可持续生物原油:工艺优化和产品表征
由于全球人口的增加和对更高质量生活的需求,世界能源需求持续增长。化石燃料不可再生,消耗化石燃料会导致全球变暖。生物质衍生燃料源自可再生原料,是化石燃料的可持续替代品。本研究调查了在相同条件下通过水热液化加拿大农作物秸秆生产生物原油的情况。此外,还发现大麦秸秆具有良好的前景;因此,改变了大麦秸秆的水热液化工艺参数,以便在氧气含量较低的情况下最大限度地提高生物原油产量。在最佳反应条件下,生产出的生物原油中含有羧酸、酚、醛和酮。此外,还尝试对水相的可回收性进行研究,以探索重新利用这一阶段的可能性。还研究了生物原油(主产品)和副产品(水炭、不凝性气体和水相)的物理化学特性,以确定合适的应用领域。本实验研究展示了对加拿大大麦秸秆液化行为的详细了解,用于生产生物原油,具有在现有石油精炼厂中共同精炼的巨大潜力。

期刊介绍: Fuel Processing Technology (FPT) deals with the scientific and technological aspects of converting fossil and renewable resources to clean fuels, value-added chemicals, fuel-related advanced carbon materials and by-products. In addition to the traditional non-nuclear fossil fuels, biomass and wastes, papers on the integration of renewables such as solar and wind energy and energy storage into the fuel processing processes, as well as papers on the production and conversion of non-carbon-containing fuels such as hydrogen and ammonia, are also welcome. While chemical conversion is emphasized, papers on advanced physical conversion processes are also considered for publication in FPT. Papers on the fundamental aspects of fuel structure and properties will also be considered.
